What is air pollution?

What causes air pollution, effects of air pollution, air pollution in the united states, air pollution and environmental justice, controlling air pollution, how to help reduce air pollution, how to protect your health.

Air pollution  refers to the release of pollutants into the air—pollutants that are detrimental to human health and the planet as a whole. According to the  World Health Organization (WHO) , each year, indoor and outdoor air pollution is responsible for nearly seven million deaths around the globe. Ninety-nine percent of human beings currently breathe air that exceeds the WHO’s guideline limits for pollutants, with those living in low- and middle-income countries suffering the most. In the United States, the  Clean Air Act , established in 1970, authorizes the U.S. Environmental Protection Agency (EPA) to safeguard public health by regulating the emissions of these harmful air pollutants.

“Most air pollution comes from energy use and production,” says  John Walke , director of the Clean Air team at NRDC. Driving a car on gasoline, heating a home with oil, running a power plant on  fracked gas : In each case, a fossil fuel is burned and harmful chemicals and gases are released into the air.

“We’ve made progress over the last 50 years in improving air quality in the United States, thanks to the Clean Air Act. But climate change will make it harder in the future to meet pollution standards, which are designed to  protect health ,” says Walke.

Air pollution is now the world’s fourth-largest risk factor for early death. According to the 2020  State of Global Air  report —which summarizes the latest scientific understanding of air pollution around the world—4.5 million deaths were linked to outdoor air pollution exposures in 2019, and another 2.2 million deaths were caused by indoor air pollution. The world’s most populous countries, China and India, continue to bear the highest burdens of disease.

“Despite improvements in reducing global average mortality rates from air pollution, this report also serves as a sobering reminder that the climate crisis threatens to worsen air pollution problems significantly,” explains  Vijay Limaye , senior scientist in NRDC’s Science Office. Smog, for instance, is intensified by increased heat, forming when the weather is warmer and there’s more ultraviolet radiation. In addition, climate change increases the production of allergenic air pollutants, including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season). “Climate change–fueled droughts and dry conditions are also setting the stage for dangerous wildfires,” adds Limaye. “ Wildfire smoke can linger for days and pollute the air with particulate matter hundreds of miles downwind.”

The effects of air pollution on the human body vary, depending on the type of pollutant, the length and level of exposure, and other factors, including a person’s individual health risks and the cumulative impacts of multiple pollutants or stressors.

Smog and soot

These are the two most prevalent types of air pollution. Smog (sometimes referred to as ground-level ozone) occurs when emissions from combusting fossil fuels react with sunlight. Soot—a type of  particulate matter —is made up of tiny particles of chemicals, soil, smoke, dust, or allergens that are carried in the air. The sources of smog and soot are similar. “Both come from cars and trucks, factories, power plants, incinerators, engines, generally anything that combusts fossil fuels such as coal, gasoline, or natural gas,” Walke says.

Smog can irritate the eyes and throat and also damage the lungs, especially those of children, senior citizens, and people who work or exercise outdoors. It’s even worse for people who have asthma or allergies; these extra pollutants can intensify their symptoms and trigger asthma attacks. The tiniest airborne particles in soot are especially dangerous because they can penetrate the lungs and bloodstream and worsen bronchitis, lead to heart attacks, and even hasten death. In  2020, a report from Harvard’s T.H. Chan School of Public Health showed that COVID-19 mortality rates were higher in areas with more particulate matter pollution than in areas with even slightly less, showing a correlation between the virus’s deadliness and long-term exposure to air pollution. 

These findings also illuminate an important  environmental justice issue . Because highways and polluting facilities have historically been sited in or next to low-income neighborhoods and communities of color, the negative effects of this pollution have been  disproportionately experienced by the people who live in these communities.

Hazardous air pollutants

A number of air pollutants pose severe health risks and can sometimes be fatal, even in small amounts. Almost 200 of them are regulated by law; some of the most common are mercury,  lead , dioxins, and benzene. “These are also most often emitted during gas or coal combustion, incineration, or—in the case of benzene—found in gasoline,” Walke says. Benzene, classified as a carcinogen by the EPA, can cause eye, skin, and lung irritation in the short term and blood disorders in the long term. Dioxins, more typically found in food but also present in small amounts in the air, is another carcinogen that can affect the liver in the short term and harm the immune, nervous, and endocrine systems, as well as reproductive functions.  Mercury  attacks the central nervous system. In large amounts, lead can damage children’s brains and kidneys, and even minimal exposure can affect children’s IQ and ability to learn.

Another category of toxic compounds, polycyclic aromatic hydrocarbons (PAHs), are by-products of traffic exhaust and wildfire smoke. In large amounts, they have been linked to eye and lung irritation, blood and liver issues, and even cancer.  In one study , the children of mothers exposed to PAHs during pregnancy showed slower brain-processing speeds and more pronounced symptoms of ADHD.

Greenhouse gases

While these climate pollutants don’t have the direct or immediate impacts on the human body associated with other air pollutants, like smog or hazardous chemicals, they are still harmful to our health. By trapping the earth’s heat in the atmosphere, greenhouse gases lead to warmer temperatures, which in turn lead to the hallmarks of climate change: rising sea levels, more extreme weather, heat-related deaths, and the increased transmission of infectious diseases. In 2021, carbon dioxide accounted for roughly 79 percent of the country’s total greenhouse gas emissions, and methane made up more than 11 percent. “Carbon dioxide comes from combusting fossil fuels, and methane comes from natural and industrial sources, including large amounts that are released during oil and gas drilling,” Walke says. “We emit far larger amounts of carbon dioxide, but methane is significantly more potent, so it’s also very destructive.” 

Another class of greenhouse gases,  hydrofluorocarbons (HFCs) , are thousands of times more powerful than carbon dioxide in their ability to trap heat. In October 2016, more than 140 countries signed the Kigali Agreement to reduce the use of these chemicals—which are found in air conditioners and refrigerators—and develop greener alternatives over time. (The United States officially signed onto the  Kigali Agreement in 2022.)

Pollen and mold

Mold and allergens from trees, weeds, and grass are also carried in the air, are exacerbated by climate change, and can be hazardous to health. Though they aren’t regulated, they can be considered a form of air pollution. “When homes, schools, or businesses get water damage, mold can grow and produce allergenic airborne pollutants,” says Kim Knowlton, professor of environmental health sciences at Columbia University and a former NRDC scientist. “ Mold exposure can precipitate asthma attacks  or an allergic response, and some molds can even produce toxins that would be dangerous for anyone to inhale.”

Pollen allergies are worsening  because of climate change . “Lab and field studies are showing that pollen-producing plants—especially ragweed—grow larger and produce more pollen when you increase the amount of carbon dioxide that they grow in,” Knowlton says. “Climate change also extends the pollen production season, and some studies are beginning to suggest that ragweed pollen itself might be becoming a more potent allergen.” If so, more people will suffer runny noses, fevers, itchy eyes, and other symptoms. “And for people with allergies and asthma, pollen peaks can precipitate asthma attacks, which are far more serious and can be life-threatening.”

More than one in three U.S. residents—120 million people—live in counties with unhealthy levels of air pollution, according to the  2023  State of the Air  report by the American Lung Association (ALA). Since the annual report was first published, in 2000, its findings have shown how the Clean Air Act has been able to reduce harmful emissions from transportation, power plants, and manufacturing.

Recent findings, however, reflect how climate change–fueled wildfires and extreme heat are adding to the challenges of protecting public health. The latest report—which focuses on ozone, year-round particle pollution, and short-term particle pollution—also finds that people of color are 61 percent more likely than white people to live in a county with a failing grade in at least one of those categories, and three times more likely to live in a county that fails in all three.

In rankings for each of the three pollution categories covered by the ALA report, California cities occupy the top three slots (i.e., were highest in pollution), despite progress that the Golden State has made in reducing air pollution emissions in the past half century. At the other end of the spectrum, these cities consistently rank among the country’s best for air quality: Burlington, Vermont; Honolulu; and Wilmington, North Carolina. 

No one wants to live next door to an incinerator, oil refinery, port, toxic waste dump, or other polluting site. Yet millions of people around the world do, and this puts them at a much higher risk for respiratory disease, cardiovascular disease, neurological damage, cancer, and death. In the United States, people of color are 1.5 times more likely than whites to live in areas with poor air quality, according to the ALA.

Historically, racist zoning policies and discriminatory lending practices known as  redlining  have combined to keep polluting industries and car-choked highways away from white neighborhoods and have turned communities of color—especially low-income and working-class communities of color—into sacrifice zones, where residents are forced to breathe dirty air and suffer the many health problems associated with it. In addition to the increased health risks that come from living in such places, the polluted air can economically harm residents in the form of missed workdays and higher medical costs.

Environmental racism isn't limited to cities and industrial areas. Outdoor laborers, including the estimated three million migrant and seasonal farmworkers in the United States, are among the most vulnerable to air pollution—and they’re also among the least equipped, politically, to pressure employers and lawmakers to affirm their right to breathe clean air.

Recently,  cumulative impact mapping , which uses data on environmental conditions and demographics, has been able to show how some communities are overburdened with layers of issues, like high levels of poverty, unemployment, and pollution. Tools like the  Environmental Justice Screening Method  and the EPA’s  EJScreen  provide evidence of what many environmental justice communities have been explaining for decades: that we need land use and public health reforms to ensure that vulnerable areas are not overburdened and that the people who need resources the most are receiving them.

In the United States, the  Clean Air Act  has been a crucial tool for reducing air pollution since its passage in 1970, although fossil fuel interests aided by industry-friendly lawmakers have frequently attempted to  weaken its many protections. Ensuring that this bedrock environmental law remains intact and properly enforced will always be key to maintaining and improving our air quality.

But the best, most effective way to control air pollution is to speed up our transition to cleaner fuels and industrial processes. By switching over to renewable energy sources (such as wind and solar power), maximizing fuel efficiency in our vehicles, and replacing more and more of our gasoline-powered cars and trucks with electric versions, we'll be limiting air pollution at its source while also curbing the global warming that heightens so many of its worst health impacts.

And what about the economic costs of controlling air pollution? According to a report on the Clean Air Act commissioned by NRDC, the annual  benefits of cleaner air  are up to 32 times greater than the cost of clean air regulations. Those benefits include up to 370,000 avoided premature deaths, 189,000 fewer hospital admissions for cardiac and respiratory illnesses, and net economic benefits of up to $3.8 trillion for the U.S. economy every year.

“The less gasoline we burn, the better we’re doing to reduce air pollution and the harmful effects of climate change,” Walke explains. “Make good choices about transportation. When you can, ride a bike, walk, or take public transportation. For driving, choose a car that gets better miles per gallon of gas or  buy an electric car .” You can also investigate your power provider options—you may be able to request that your electricity be supplied by wind or solar. Buying your food locally cuts down on the fossil fuels burned in trucking or flying food in from across the world. And most important: “Support leaders who push for clean air and water and responsible steps on climate change,” Walke says.

  • “When you see in the news or hear on the weather report that pollution levels are high, it may be useful to limit the time when children go outside or you go for a jog,” Walke says. Generally, ozone levels tend to be lower in the morning.
  • If you exercise outside, stay as far as you can from heavily trafficked roads. Then shower and wash your clothes to remove fine particles.
  • The air may look clear, but that doesn’t mean it’s pollution free. Utilize tools like the EPA’s air pollution monitor,  AirNow , to get the latest conditions. If the air quality is bad, stay inside with the windows closed.
  • If you live or work in an area that’s prone to wildfires,  stay away from the harmful smoke  as much as you’re able. Consider keeping a small stock of masks to wear when conditions are poor. The most ideal masks for smoke particles will be labelled “NIOSH” (which stands for National Institute for Occupational Safety and Health) and have either “N95” or “P100” printed on it.
  • If you’re using an air conditioner while outdoor pollution conditions are bad, use the recirculating setting to limit the amount of polluted air that gets inside.

4 Causes and Effects of Air Pollution

4 Causes and Effects of Air Pollution

Air pollution refers to the release of pollutants into the air, which can be harmful and impose significant health risks to the population, including increased chances of coronary and respiratory diseases, as well as preliminary deaths. Made up of chemicals and pollutant particles, air pollution is one of the biggest environmental problems of our lifetime . Read on to learn about the major causes and effects of air pollution. 

Sources of Air Pollution

1. burning fossil fuels.

The biggest contributors of air pollution are from industry sources and power plants to generate power, as well as fossil fuel motor vehicles. The continuous burning of fossil fuels releases air pollutants, emissions and chemicals into the air and atmosphere. 

In 2020, the Environmental Protection Agency reported that about 68 million tons of air pollution were emitted into the atmosphere in the US, contributing to the “formation of ozone and particles, the deposition of acids, and visibility impairment.”

The World Health Organization (WHO) estimates around 91% of the world’s population lives in places where air quality levels exceed limits. Developing and low-income countries experienced the greatest impacts from outdoor air pollution, particularly in the Western Pacific and South-East Asia regions. 

Climate change has an interrelated relationship with the environment and air pollution. As more air pollutants and greenhouse gases are released, this alters the energy balance between the atmosphere and the Earth’s surface , which leads to global warming. The global temperature increase in turns raises the production of allergenic air pollutants such as mold and extends pollen seasons. 

2. Ozone and Smog

Ozone is a gas that when it forms air pollution and reaches too close to the ground, it significantly reduces visibility. We call this smog. This form of air pollution occurs when sunlight reacts with nitrogen oxides released from car exhausts and coal power plants. The ozone typically forms a protective layer in the atmosphere to protect the population from ultraviolet radiation (UV), but as it transforms into smog, it is harmful to human health and poses higher risks of respiratory illnesses like asthma and lung cancer. 

3. Weather Conditions

Air pollution and poor air quality can be attributed to changing weather conditions. For example, dust storms in China would carry clouds of industrial pollutants and particulate pollution across the Gobi desert into neighbouring countries such as Korea and Japan during spring season. Likewise during periods of high air pressure, air becomes stagnant and pollutants are more concentrated over certain areas. 

4. Heatwaves and Wildfires

Heatwaves not only lead to an increase of temperature, but are some of the causes and effects of air pollution. Hotter, stagnant air during a heat wave increases the concentration of particle pollutants. Extreme heat wave events also have higher risks of large-scale wildfires, which in turn, releases more carbon emissions, smog and pollutants into the air.

Effects of Air Pollution 

Air pollution contributes to the death of 5 million every year and about 6% of the global population, according to Our World in Data . The lethal combination of outdoor air pollution and toxic emissions from burning fossil fuel has been one of the leading causes of chronic and often terminal health issues including heart disease, stroke, lung cancer, and lower respiratory infections. 

The WHO estimates that nine out of 10 people breathe air that contains high levels of pollutants. In 2017, close to 15% of population deaths in low income countries like South and East Asia are attributed to air pollution, while the higher income countries experience only about 2%. 

The drastic difference in mortality numbers can be linked to legislations such as the Clean Air Act implemented by high-income countries like the US. Such legislations usually establishes national air quality standards and regulations on hazardous air pollutants. The UK in particular, saw a sharp 60% decline in air pollutant emissions between the 1970 and 2016. 

The environmental effects of air pollution are also vast, ranging from acid rain to contributing to birth defects, reproductive failure, and diseases in wildlife animals. Agriculture is also a victim of air pollution as increased pollutants can affect crop and forest yields, reduce growth  and increased plant susceptibility to disease from increased UV radiation caused by ozone depletion.

In the wake of the COVID-19 pandemic, air pollution has once again returned to the spotlight in relation to its role in transmitting virus molecules. Preliminary studies have identified a positive correlation between COVID-19-related mortalities and air pollution. China, being one of the most polluted countries in the world, can potentially link its high death toll during the pandemic to its poor air quality. Although, more research needs to be conducted to make any substantive correlation.

Essay on Air Pollution

Environmental changes are caused by the natural or artificial content of harmful pollutants and can cause instability, disturbance, or adverse effects on the ecosystem. Earth and its environment pose a more serious threat due to the increasing pollution of air, water, and soil. Environmental damage is caused by improper resource management or careless human activities. Therefore, any activity that violates the original nature of the environment and leads to degradation is called pollution. We need to understand the origin of these pollutants and find ways to control pollution. This can also be done by raising awareness of the effects of pollutants.

Air pollution is any physical, chemical, or biological change in the air. A certain percentage of the gas is present in the atmosphere. Increasing or decreasing the composition of these gasses is detrimental to survival. This imbalance in gas composition causes an increase in global temperature which is called global warming.

Introduction to air pollution 

The Earth and its environment are facing a serious threat by the increasing pollution of the air, water, and soil—the vital life support systems of the Earth. The damage to the environment is caused by improper management of resources or by careless human activity. Hence any activity that violates the original character of nature and leads to its degradation is called pollution. We need to understand the sources of these pollutants and find ways to control pollution. This can be also done by making people aware of the effects of pollutants. 

Air with 78% Nitrogen, 21% Oxygen, and 1% of all other gasses support life on Earth. Various processes take place to sustain the regular percentage of gasses and their composition in general. 

Atmospheric pollution can have natural sources, for example, volcanic eruptions. The gaseous by-products of man-made processes such as energy production, waste incineration, transport, deforestation and agriculture, are the major air pollutants.

Although air is made up of mostly Oxygen and Nitrogen, mankind, through pollution, has increased the levels of many trace gasses, and in some cases, released completely new gasses to the atmosphere. 

Air pollution can result in poor air quality, both in cities and in the countryside. Some air pollutants make people sick, causing breathing problems and increasing the likelihood of cancer. 

Some air pollutants are harmful to plants, animals, and the ecosystems in which they live. Statues, monuments, and buildings are being corroded by the air pollutants in the form of acid rain. It also damages crops and forests, and makes lakes and streams unsuitable for fish and other plant and animal life. 

Air pollution created by man-made resources is also changing the Earth’s atmosphere. It is causing the depletion of the ozone layer and letting in more harmful radiation from the Sun. The greenhouse gasses released into the atmosphere prevents heat from escaping back into space and leads to a rise in global average temperatures. Global warming affects the average sea-level and increases the spread of tropical diseases.

Air pollution occurs when large amounts of gas and tiny particles are released into the air and the ecological balance is disturbed. Each year millions of tons of gasses and particulate matter are emitted into the air. 

Primary air pollutants are pollutants, which are directly released into the air. They are called SPM, i.e., Suspended Particulate Matter. For example, smoke, dust, ash, sulfur oxide, nitrogen oxide, and radioactive compounds, etc.

Secondary Pollutants are pollutants, which are formed due to chemical interactions between the atmospheric components and primary pollutants. For example, Smog (i.e. Smoke and fog), ozone, etc.

Major gaseous air pollutants include Carbon Dioxide, Hydrogen Sulfide, Sulfur Dioxide and Nitrogen Oxide, etc.

Natural sources are volcanic eruptions, forest fires, dust storms, etc. 

Man-made sources include gasses released from the automobiles, industries, burning of garbage and bricks kilns, etc.

Effects of Air Pollution on Human Health

Air pollution has adverse effects on human health. 

Breathing polluted air puts you at higher risk of asthma.

When exposed to ground ozone for 6 to 7 hours, people suffer from respiratory inflammation.

Damages the immune system, endocrine, and reproductive systems.

A high level of air pollution has been associated with higher incidents of heart problems.

The toxic chemicals released into the air are affecting the flora and fauna immensely.

Preventive Measures to Reduce Air Pollution

We can prevent pollution by utilizing raw materials, water energy, and other resources more efficiently. When less harmful substances are substituted for hazardous ones, and when toxic substances are eliminated from the production process, human health can be protected and economic wellbeing can be strengthened. 

There are several measures that can be adopted by people to reduce pollution and to save the environment.

Carpooling.

Promotion of public transport.

No smoking zone.

Restricted use of fossil fuels.

Saving energy.

Encouraging organic farming.

The government has put restrictions on the amount of fossil fuels that can be used as well as restrictions on how much carbon dioxide and other pollutants can be emitted. Although the government is attempting to save our environment from these harmful gasses, it is not sufficient. We as a society need to keep the environment clean by controlling the pollution of air.

FAQs on Air Pollution Essay

1. State the Causes of Air Pollution ?

The following are the causes of air pollution.

Vehicular pollution consisting of Carbon Monoxide causes pollution.

Emission of Nitrogen oxide by a large number of supersonic transport airplanes causes deterioration of the Ozone layer and also causes serious damage to the flora and fauna.

The release of Chlorofluorocarbons into the Stratosphere causes depletion of Ozone, which is a serious concern to animals, microscopic, and aquatic organisms.

Burning garbage causes smoke, which pollutes the atmosphere. This smoke contains harmful gases such as Carbon dioxide and Nitrogen oxides.

In India, brick kilns are used for many purposes and coal is used to burn the bricks. They give out huge quantities of Carbon dioxide and particulate matter such as smoke, dust that are very harmful to people working there and the areas surrounding it. 

Many cleansing agents release poisonous gases such as Ammonia and Chlorine into the atmosphere. 

Radioactive elements emit harmful rays into the air.

Decomposed animals and plants emit Methane and Ammonia gas into the air.

2. What Does Global Warming Mean?

Global warming is the gradual rising average temperature of the Earth's atmosphere due to the concentration of methane in certain toxic gasses such as carbon dioxide. This has a major impact on the world climate. The world is warming. The land and the sea are now warmer than they were at the beginning and temperatures are still rising. This rise in temperature is, in short, global warming. This temperature rise is man-made. The burning of fossil fuels releases greenhouse gasses into the atmosphere which capture solar heat and raise surface and air temperatures.

3. Name the Alternative Modes of Transport. In What Way Does it Help to Reduce Air Pollution?

Public transport could be an alternative mode of transport. Public transport like trains, buses and trams, can relieve traffic congestion and reduce air pollution from road transport. The use of public transport must be encouraged in order to develop a sustainable transport policy.

4. Mention other means of transportation! How can I help reduce air pollution?

Public transportation can be another mode of transportation. Public transport such as trains, buses and trams can reduce traffic congestion and reduce air pollution from road transport. The use of public transport and to develop sustainable transport policies should be encouraged. While one passenger vehicle has the convenience factor, other modes of transportation reduce travel costs, spend less time, reduce stress, improve health, and reduce energy consumption and parking. Other trips for work include walking/cycling, public transport, hybrid travel and transport.

5. What are the effects of pollution?

Excessive air pollution can increase the risk of heart attack, wheezing, coughing and difficulty breathing, as well as irritation of the eyes, nose and throat. Air pollution can also cause heart problems, asthma, and other lung problems. Due to the emission of greenhouse gases, the composition of the air in the air is disturbed. This causes an increase in global temperature. The damaging ozone layer due to air pollution does not prevent harmful ultraviolet rays from the sun, which cause skin and eye problems in individuals. Air pollution has caused a number of respiratory and heart diseases among people. The incidence of lung cancer has increased in recent decades. Children living in contaminated areas are more likely to develop pneumonia and asthma. Many people die every year due to the direct or indirect effects of air pollution. When burning fossil fuels, harmful gases such as nitrogen oxides and sulfur oxides are released into the air. Water droplets combine with these pollutants and become acidic and fall as acid rain, which harms human, animal and plant life.

6. What is the solution to air pollution?

Production of renewable fuels and clean energy. The basic solution to air pollution is to get away from fossil fuels and replace them with other energies such as solar, wind and geothermal. The government limits the amount of fossil fuel that can be used and how much carbon dioxide and other pollutants it can emit. While the government is trying to save our environment from this harmful gas, it is not enough. We as a society need to keep the environment clean by controlling air pollution.

ENCYCLOPEDIC ENTRY

Air pollution.

Air pollution consists of chemicals or particles in the air that can harm the health of humans, animals, and plants. It also damages buildings.

Biology, Ecology, Earth Science, Geography

Morgan Stanley

Air pollution consists of chemicals or particles in the air that can harm the health of humans, animals, and plants. It also damages buildings. Pollutants in the air take many forms. They can be gases , solid particles, or liquid droplets. Sources of Air Pollution Pollution enters the Earth's atmosphere in many different ways. Most air pollution is created by people, taking the form of emissions from factories, cars, planes, or aerosol cans . Second-hand cigarette smoke is also considered air pollution. These man-made sources of pollution are called anthropogenic sources . Some types of air pollution, such as smoke from wildfires or ash from volcanoes , occur naturally. These are called natural sources . Air pollution is most common in large cities where emissions from many different sources are concentrated . Sometimes, mountains or tall buildings prevent air pollution from spreading out. This air pollution often appears as a cloud making the air murky. It is called smog . The word "smog" comes from combining the words "smoke" and " fog ." Large cities in poor and developing nations tend to have more air pollution than cities in developed nations. According to the World Health Organization (WHO) , some of the worlds most polluted cities are Karachi, Pakistan; New Delhi, India; Beijing, China; Lima, Peru; and Cairo, Egypt. However, many developed nations also have air pollution problems. Los Angeles, California, is nicknamed Smog City. Indoor Air Pollution Air pollution is usually thought of as smoke from large factories or exhaust from vehicles. But there are many types of indoor air pollution as well. Heating a house by burning substances such as kerosene , wood, and coal can contaminate the air inside the house. Ash and smoke make breathing difficult, and they can stick to walls, food, and clothing. Naturally-occurring radon gas, a cancer -causing material, can also build up in homes. Radon is released through the surface of the Earth. Inexpensive systems installed by professionals can reduce radon levels. Some construction materials, including insulation , are also dangerous to people's health. In addition, ventilation , or air movement, in homes and rooms can lead to the spread of toxic mold . A single colony of mold may exist in a damp, cool place in a house, such as between walls. The mold's spores enter the air and spread throughout the house. People can become sick from breathing in the spores. Effects On Humans People experience a wide range of health effects from being exposed to air pollution. Effects can be broken down into short-term effects and long-term effects . Short-term effects, which are temporary , include illnesses such as pneumonia or bronchitis . They also include discomfort such as irritation to the nose, throat, eyes, or skin. Air pollution can also cause headaches, dizziness, and nausea . Bad smells made by factories, garbage , or sewer systems are considered air pollution, too. These odors are less serious but still unpleasant . Long-term effects of air pollution can last for years or for an entire lifetime. They can even lead to a person's death. Long-term health effects from air pollution include heart disease , lung cancer, and respiratory diseases such as emphysema . Air pollution can also cause long-term damage to people's nerves , brain, kidneys , liver , and other organs. Some scientists suspect air pollutants cause birth defects . Nearly 2.5 million people die worldwide each year from the effects of outdoor or indoor air pollution. People react differently to different types of air pollution. Young children and older adults, whose immune systems tend to be weaker, are often more sensitive to pollution. Conditions such as asthma , heart disease, and lung disease can be made worse by exposure to air pollution. The length of exposure and amount and type of pollutants are also factors. Effects On The Environment Like people, animals, and plants, entire ecosystems can suffer effects from air pollution. Haze , like smog, is a visible type of air pollution that obscures shapes and colors. Hazy air pollution can even muffle sounds. Air pollution particles eventually fall back to Earth. Air pollution can directly contaminate the surface of bodies of water and soil . This can kill crops or reduce their yield . It can kill young trees and other plants. Sulfur dioxide and nitrogen oxide particles in the air, can create acid rain when they mix with water and oxygen in the atmosphere. These air pollutants come mostly from coal-fired power plants and motor vehicles . When acid rain falls to Earth, it damages plants by changing soil composition ; degrades water quality in rivers, lakes and streams; damages crops; and can cause buildings and monuments to decay . Like humans, animals can suffer health effects from exposure to air pollution. Birth defects, diseases, and lower reproductive rates have all been attributed to air pollution. Global Warming Global warming is an environmental phenomenon caused by natural and anthropogenic air pollution. It refers to rising air and ocean temperatures around the world. This temperature rise is at least partially caused by an increase in the amount of greenhouse gases in the atmosphere. Greenhouse gases trap heat energy in the Earths atmosphere. (Usually, more of Earths heat escapes into space.) Carbon dioxide is a greenhouse gas that has had the biggest effect on global warming. Carbon dioxide is emitted into the atmosphere by burning fossil fuels (coal, gasoline , and natural gas ). Humans have come to rely on fossil fuels to power cars and planes, heat homes, and run factories. Doing these things pollutes the air with carbon dioxide. Other greenhouse gases emitted by natural and artificial sources also include methane , nitrous oxide , and fluorinated gases. Methane is a major emission from coal plants and agricultural processes. Nitrous oxide is a common emission from industrial factories, agriculture, and the burning of fossil fuels in cars. Fluorinated gases, such as hydrofluorocarbons , are emitted by industry. Fluorinated gases are often used instead of gases such as chlorofluorocarbons (CFCs). CFCs have been outlawed in many places because they deplete the ozone layer . Worldwide, many countries have taken steps to reduce or limit greenhouse gas emissions to combat global warming. The Kyoto Protocol , first adopted in Kyoto, Japan, in 1997, is an agreement between 183 countries that they will work to reduce their carbon dioxide emissions. The United States has not signed that treaty . Regulation In addition to the international Kyoto Protocol, most developed nations have adopted laws to regulate emissions and reduce air pollution. In the United States, debate is under way about a system called cap and trade to limit emissions. This system would cap, or place a limit, on the amount of pollution a company is allowed. Companies that exceeded their cap would have to pay. Companies that polluted less than their cap could trade or sell their remaining pollution allowance to other companies. Cap and trade would essentially pay companies to limit pollution. In 2006 the World Health Organization issued new Air Quality Guidelines. The WHOs guidelines are tougher than most individual countries existing guidelines. The WHO guidelines aim to reduce air pollution-related deaths by 15 percent a year. Reduction Anybody can take steps to reduce air pollution. Millions of people every day make simple changes in their lives to do this. Taking public transportation instead of driving a car, or riding a bike instead of traveling in carbon dioxide-emitting vehicles are a couple of ways to reduce air pollution. Avoiding aerosol cans, recycling yard trimmings instead of burning them, and not smoking cigarettes are others.

Downwinders The United States conducted tests of nuclear weapons at the Nevada Test Site in southern Nevada in the 1950s. These tests sent invisible radioactive particles into the atmosphere. These air pollution particles traveled with wind currents, eventually falling to Earth, sometimes hundreds of miles away in states including Idaho, Utah, Arizona, and Washington. These areas were considered to be "downwind" from the Nevada Test Site. Decades later, people living in those downwind areascalled "downwinders"began developing cancer at above-normal rates. In 1990, the U.S. government passed the Radiation Exposure Compensation Act. This law entitles some downwinders to payments of $50,000.

Greenhouse Gases There are five major greenhouse gases in Earth's atmosphere.

  • water vapor
  • carbon dioxide
  • nitrous oxide

London Smog What has come to be known as the London Smog of 1952, or the Great Smog of 1952, was a four-day incident that sickened 100,000 people and caused as many as 12,000 deaths. Very cold weather in December 1952 led residents of London, England, to burn more coal to keep warm. Smoke and other pollutants became trapped by a thick fog that settled over the city. The polluted fog became so thick that people could only see a few meters in front of them.

write an essay about causes and effects of air pollution

by Chris Woodford . Last updated: November 22, 2022.

Photo: Air pollution is obvious when it pours from a smokestack (chimney), but it's not always so easy to spot. This is an old photo of the kind of smoke that used to come from coal-fired power plants and, apart from soot (unburned carbon particles), its pollutants include sulfur dioxide and the greenhouse gas carbon dioxide. Thanks to tougher pollution controls, modern power plants produce only a fraction as much pollution. Modern pollution made by traffic consists of gases like nitrogen dioxide and "particulates" (microscopic soot and dust fragments) that are largely invisible.

What is air pollution?

Air pollution is a gas (or a liquid or solid dispersed through ordinary air) released in a big enough quantity to harm the health of people or other animals, kill plants or stop them growing properly, damage or disrupt some other aspect of the environment (such as making buildings crumble), or cause some other kind of nuisance (reduced visibility, perhaps, or an unpleasant odor).

Natural air pollution

Photo: Forest fires are a completely natural cause of air pollution. We'll never be able to prevent them breaking out or stop the pollution they cause; our best hope is to manage forests, where we can, so fires don't spread. Ironically, that can mean deliberately burning areas of forest, as shown here, to create firebreaks. Forests are also deliberately burned to regenerate ecosystems. Photo by courtesy of US Fish and Wildlife Service .

Top-ten kinds of air pollution Photo: Flying molecules—if you could see air pollution close up, this is what it would look like. Image courtesy of US Department of Energy. Any gas could qualify as pollution if it reached a high enough concentration to do harm. Theoretically, that means there are dozens of different pollution gases. It's important to note that not all the things we think of as pollution are gases: some are aerosols (liquids or solids dispersed through gases). In practice, about ten different substances cause most concern: Sulfur dioxide : Coal, petroleum, and other fuels are often impure and contain sulfur as well as organic (carbon-based) compounds. When sulfur (spelled "sulphur" in some countries) burns with oxygen from the air, sulfur dioxide (SO 2 ) is produced. Coal-fired power plants are the world's biggest source of sulfur-dioxide air pollution, which contributes to smog, acid rain, and health problems that include lung disease. [5] Large amounts of sulfur dioxide are also produced by ships, which use dirtier diesel fuel than cars and trucks. [6] Carbon monoxide : This highly dangerous gas forms when fuels have too little oxygen to burn completely. It spews out in car exhausts and it can also build up to dangerous levels inside your home if you have a poorly maintained gas boiler , stove, or fuel-burning appliance. (Always fit a carbon monoxide detector if you burn fuels indoors.) [7] Carbon dioxide : This gas is central to everyday life and isn't normally considered a pollutant: we all produce it when we breathe out and plants such as crops and trees need to "breathe" it in to grow. However, carbon dioxide is also a greenhouse gas released by engines and power plants. Since the beginning of the Industrial Revolution, it's been building up in Earth's atmosphere and contributing to the problem of global warming and climate change . [8] Nitrogen oxides : Nitrogen dioxide (NO 2 ) and nitrogen oxide (NO) are pollutants produced as an indirect result of combustion, when nitrogen and oxygen from the air react together. Nitrogen oxide pollution comes from vehicle engines and power plants, and plays an important role in the formation of acid rain, ozone and smog. Nitrogen oxides are also "indirect greenhouse gases" (they contribute to global warming by producing ozone, which is a greenhouse gas). [9] Volatile organic compounds (VOCs) : These carbon-based (organic) chemicals evaporate easily at ordinary temperatures and pressures, so they readily become gases. That's precisely why they're used as solvents in many different household chemicals such as paints , waxes, and varnishes. Unfortunately, they're also a form of air pollution: they're believed to have long-term (chronic) effects on people's health and they play a role in the formation of ozone and smog. VOCs are also released by tobacco smoke and wildfires. [10] Particulates : There are many different kinds of particulates, from black soot in diesel exhaust to dust and organic matter from the desert. Airborne liquid droplets from farm pollution also count as particulates. Particulates of different sizes are often referred to by the letters PM followed by a number, so PM 10 means soot particles of less than 10 microns (10 millionths of a meter or 10µm in diameter, roughly 10 times thinner than a thick human hair). The smaller ("finer") the particulates, the deeper they travel into our lungs and the more dangerous they are. PM 2.5 particulates are much more dangerous (they're less than 2.5 millionths of a meter or about 40 times thinner than a typical hair). In cities, most particulates come from traffic fumes. [11] Ozone : Also called trioxygen, this is a type of oxygen gas whose molecules are made from three oxygen atoms joined together (so it has the chemical formula O 3 ), instead of just the two atoms in conventional oxygen (O 2 ). In the stratosphere (upper atmosphere), a band of ozone ("the ozone layer") protects us by screening out harmful ultraviolet radiation (high-energy blue light) beaming down from the Sun. At ground level, it's a toxic pollutant that can damage health. It forms when sunlight strikes a cocktail of other pollution and is a key ingredient of smog (see box below). [12] Chlorofluorocarbons (CFCs) : Once thought to be harmless, these gases were widely used in refrigerators and aerosol cans until it was discovered that they damaged Earth's ozone layer. We discuss this in more detail down below. [13] Unburned hydrocarbons : Petroleum and other fuels are made of organic compounds based on chains of carbon and hydrogen atoms. When they burn properly, they're completely converted into harmless carbon dioxide and water ; when they burn incompletely, they can release carbon monoxide or float into the air in their unburned form, contributing to smog. Lead and heavy metals : Lead and other toxic "heavy metals" can be spread into the air either as toxic compounds or as aerosols (when solids or liquids are dispersed through gases and carried through the air by them) in such things as exhaust fumes and the fly ash (contaminated waste dust) from incinerator smokestacks. [14] What are the causes of air pollution?

Chart: Most of the world's major cities routinely exceed World Health Organization (WHO) air pollution guidelines, though progress is being made: you can see that the 2022 figures (green) show a marked improvement on the 2016 ones (orange) in almost every case. This chart compares annual mean PM 2.5 levels in 12 representative cities around the world with the recently revised (2021) WHO guideline value of 5μg per cubic meter (dotted line). PM 2.5 particulates are those smaller than 2.5 microns and believed to be most closely linked with adverse health effects. For more about this chart and the data sources used, see note [22] .

Photo: Smokestacks billowing pollution over Moscow, Russia in 1994. Factory pollution is much less of a problem than it used to be in the world's "richer" countries—partly because a lot of their industry has been exported to nations such as China, India, and Mexico.

What effects does air pollution have?

Acid rain—a closer look.

Photo: Acid rain can turn lakes so acidic that fish no longer survive. Picture courtesy of U.S. Fish and Wildlife Service Division of Public Affairs. Why does that matter? Pure water is neither acidic nor alkaline but completely neutral (we say it has an acidity level or pH of 7.0). Ordinary rainwater is a little bit more acidic than this with about the same acidity as bananas (roughly pH 5.5), but if rain falls through sulfur dioxide pollution it can turn much more acidic (with a pH of 4.5 or lower, which is the same acidity as orange or lemon juice). When acid rain accumulates in lakes or rivers, it gradually turns the entire water more acidic. That's a real problem because fish thrive only in water that is neutral or slightly acidic (typically with a pH of 6.5–7.0). Once the acidity drops below about pH 6.0, fish soon start to die—and if the pH drops to about 4.0 or less, all the fish will be killed. Acid rain has caused major problems in lakes throughout North America and Europe. It also causes the death of forests, reduces the fertility of soil, and damages buildings by eating away stonework (the marble on the US Capitol in Washington, DC has been eroded by acid-rain, for example). One of the biggest difficulties in tackling acid rain is that it can happen over very long distances. In one notable case, sulfur dioxide air pollution produced by power plants in the UK was blamed for causing acid rain that fell on Scandinavian countries such as Norway, producing widespread damage to forests and the deaths of thousands of fish in acidified lakes. The British government refused to acknowledge the problem and that was partly why the UK became known as the "dirty man of Europe" in the 1980s and 1990s. [18] Acid rain was a particular problem in the last 30–40 years of the 20th century. Thanks to the decline in coal-fired power plants, and the sulfur dioxide they spewed out, it's less of a problem for western countries today. But it's still a big issue in places like India, where coal remains a major source of energy. Global air pollution It's hard to imagine doing anything so dramatic and serious that it would damage our entire, enormous planet—but, remarkable though it may seem, we all do things like this everyday, contributing to problems such as global warming and the damage to the ozone layer (two separate issues that are often confused). Global warming Every time you ride in a car, turn on the lights, switch on your TV , take a shower, microwave a meal, or use energy that's come from burning a fossil fuel such as oil, coal, or natural gas, you're almost certainly adding to the problem of global warming and climate change: unless it's been produced in some environmentally friendly way, the energy you're using has most likely released carbon dioxide gas into the air. While it's not an obvious pollutant, carbon dioxide has gradually built up in the atmosphere, along with other chemicals known as greenhouse gases . Together, these gases act a bit like a blanket surrounding our planet that is slowly making the mean global temperature rise, causing the climate (the long-term pattern of our weather) to change, and producing a variety of different effects on the natural world, including rising sea levels.

Essay on Air Pollution: Types, Causes & Effects of Air Pollution

March 10, 2021 by Sandeep

Air Pollution Essay: Air Pollution can be defined as the presence of toxic substances in the air in such a concentration that can be hazardous to humans and their surroundings. These toxic particles are commonly known as pollutants; out of these pollutants, oxides of carbon, nitrogen and sulphur are particularly harmful.

Essay on Air Pollution in 500 Words

Below we have provided Air Pollution Essay in English, suitable for class 3, 4, 5, 6, 7, 8, 9 and 10 school students. This essay is drafted in easy and simple language.

Air Pollution is an environmental issue that poses a huge threat to billions of organisms surviving on our planet. It has been increasing at an alarming rate with an increase in the concentration of pollutants. The contamination of air by these hazardous pollutants has disrupted the natural balance in our environment. The quality of life has reduced.

Causes of Air Pollution

Two primary phenomena cause air pollution. One of them is the natural phenomenon that comprises volcanic eruptions, wildfires, radioactive elements, and volatile organic compounds. The other most crucial cause is human activity. With the increase in the number of industries, the contamination in the air automatically increases. Fuels and chemicals utilized in factories, mills, and industries release harmful chemicals to the atmosphere. These are organic compounds, gases, particulate matter, ash, and other volatile substances.

Chlorofluorocarbons, also known as CFCs, are another potent reason for air pollution. These chemicals get released from leaky refrigerants, spray tins, burning plastics and various other sources. They deplete the ozone layer and allow harmful UV rays to enter our atmosphere. This, in turn, causes serious illnesses. It is also responsible for smog in urban cities. Smog impairs visibility and can lead to accidents.

Carbon dioxide solely accounts for almost 57 percent of the air pollution. Greenhouse gases and Carbon dioxide together contribute to global warming . They also cause acid rains which are harmful to plants and man-made objects like ancient monuments.

Air Pollution Essay

Effects of Air Pollution

With the air quality deteriorating, our future is at stake. Increasing pollution can cause serious health hazards like cancer and cardiovascular issues. Children suffer from bronchitis and pneumonia. Irritation of the nose and throat, asthma attacks, pulmonary diseases are all outcomes of air pollution. Another significant effect of pollution is extreme climate change. Disrupting food chains, extinction of species, depleting the ozone layer are some of the grave issues we face today.

Control of Air Pollution

The Air Pollution Act forbids power sectors and high-scale industries from releasing particulate matter beyond a certain level. Chimneys, Electrostatic precipitators, and filters must be implanted to lessen the damage caused by the emissions.

People must be made aware of the grave conditions of air pollution. The government has taken a huge step to sensitize people regarding the consequences of pollution. We must do our part as well. Using the means of public transport will ensure less number of vehicles. Lesser vehicles mean lesser emission of pollutants.

Planting more and more trees can help solve this crisis. Reforestation in mining areas is also an effective step. Conservation of energy is of prime importance. Renewable energy sources like solar panels, wind turbines, hydroelectric power, and natural gas must be utilized. We must avoid burning dry leaves at our homes and must indulge in the habit of composting.

The implementation of Eco-friendly methods will ensure a cleaner and healthier environment. LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas), and Biogas are some Eco-friendly substitutes of fuels. Together, we must strive to bring a change. Our efforts matter because they will bring in much-needed change. After all, everyone wants to live on a healthy planet.

Air Pollution Effects on the Health and Environment Essay

  • As a template for you assignment

According to the National Ambient Air Quality Standards, there are six principal air pollutants, the excess of which critically affects the health, lifestyle, and welfare of the population. They are carbon monoxide, lead, nitrogen dioxide, ozone, particle pollution, and sulfur dioxide. Increasing the level of each of them will most likely have critical consequences, and should be regulated by governmental services. Still, to my mind, the priority should be given to the regulation of particle pollution as the most dangerous issue.

Particle pollution or “Particulate matter,” PM, is an effect caused by contamination of air by the particles of different origin. They might be dust, small droplets of nitric and sulfuric acids, coal and metal particles, organic chemicals, etc. The particles are subdivided into two groups. The size of “inhalable coarse particles” lies within the range of 2.5 and 10 micrometers (“The United States Environmental Protection Agency: Particulate Matter” par. 3). “Fine particles” are 2.5 micrometers and smaller (“The United States Environmental Protection Agency: Particulate Matter” par. 4). The particles are majorly concentrated along the roadways and in the areas of dusty industries. Forest fires, being a significant issue recently all over the U.S., are a substantial source of PM (Langmann et al. 109). Gas emissions from cars, industries, and power plants also contribute to particle pollution.

The level of particle pollution is regulated both by primary and secondary standards, meaning that high levels of PM will affect both sensitive categories of people and the welfare such as animals, crops, and buildings. The health dangers lay within lungs and heart disease that might cause death, as well as asthma, heart attacks, respiratory symptoms, etc. In general, 500,000 deaths occur due to particle pollution annually (Nel, 804). The damage to welfare and environment can be described as contamination of water bodies with acids, affecting the nutrient balance of soils and coastal waters, destroying forests and crops. Acid rains “resulted by sulfur oxides transformation into acids, especially sulfuric acid, besides causing leaf burns, contribute to the acidity increase of naturally acid soils and to lowering the buffering capacity of base saturated top soils” (Lacatusu, Cimpeanu and Lungu 818) are also the result of particle pollution. PM can also cause discomfort and danger, conducting a reduction of visibility.

The factor that demonstrates the extreme danger and the priority of dealing with an issue of particle pollutions is that its standard was reviewed in 2012 the latest date if compare to revisions of other major pollutants (“The United States Environmental Protection Agency: National Ambient Air Quality Standards” par.3). The general recommendations to reduce particle pollution on the household level include not to burn leaves, use the energy sources thoughtfully, avoid using fireplaces and dust-producing devices. These measures are high, but some more effective means should be provided on the state level. They might be introducing the policy of power plants emission reduction by providing more environmental-friendly technologies. This also refers to encouraging using a vehicle with low rates of dangerous emissions. The practice of short-term air pollution forecasts and the regulation of the industrial and household emissions in the area, based on those forecasts (Berlyand 12), seems to be a good idea. The policy of forest fires prevention also should be improved.

Particle pollution is one of the major issues affecting the environment all over the United States. As is, it occurs due to industrial problems and natural catastrophes and might result in drastic consequences for the population’s health and welfare; the environmental policy should be reviewed to reduce the rates of pollution.

Causes and Effects of Pollution

The environment people live in is affecting them, including health and lifestyle, and the nature around them, like plants, animals, water bodies, and the atmosphere. Environmental issues caused by humans using natural resources and treating nature with no respect have resulted in some negative changes. One of the most significant problems people are facing nowadays is pollution. It affects all the crucial elements for sustaining human life: water, air, and soil. The causes and effects of pollution are multiple and varied, and they should be examined closely to better understand this phenomenon.

General reasons for pollution include major emissions of carbon dioxide, as well as the chemicals produced as the result of the burning of fossil fuels. This happens because of different factories’ activity and their waste, which is being discharged into water, soil, and the atmosphere. Other than big manufacturing elements, pollution is caused by people individually. This involves emissions caused by cars, using much energy for different activities, and producing enormous amounts of waste, especially the types that are not decomposable or take hundreds of years to do so.

The first side of the environment impacted by pollution is the atmosphere. Air pollution can be defined as a combination of harmful gases or particles that accumulate in the air in unsafe quantities. The worsening air quality can result in multiple health issues, including “heart disease, lung cancer, and both chronic and acute respiratory diseases” (“Ambient (outdoor) air pollution,” 2018, para. 1). As air quality is measured around the world, many deficiencies are detected, which directly influence human life.

According to the World Health Organization data, in 2016, about 91 percent of the population inhabited places with unsatisfactory air quality (as cited in “Ambient (outdoor) air pollution,” 2018). Therefore, air pollution is affecting not only those living in big urban areas but is also spreading around the whole planet.

Water covers the majority of the planet, so water pollution is also a crucial problem. Wastewater and emission of fertilizers into water bodies cause water pollution, which can make water harmful to human consumption. Other than becoming undrinkable, contaminated water will affect or even kill aquatic creatures and plants, as well as transfer to crops, making them just as dangerous. The United Nations World Water Development Report stated that over 80 percent of wastewater is discharged back into the environment, not being appropriately treated (2017). Thus, not only do the major water bodies become largely polluted but the effect is also transferred to soil.

As a significant part of the food for humans and domestic animals is grown, polluted soil can also cause complications. Soil pollution occurs when certain toxic chemicals are gathered in large amounts. Soil can be affected by harmful substances as a result of industrial waste emission into the ground, contaminated water interacting with it, or excessive amounts of pesticides or fertilizers being used. As a result, plants and crops become dangerous for human consumption and can cause multiple health problems.

Pollution is a global phenomenon, causing much damage to the planet and harming people and other living creatures. It can manifest in different forms, but its impact is hugely detrimental. Seeking solutions for this problem is now one of the main agendas for the whole of humankind, which can only be done with combined efforts of government structures and community and individual actions. Only by being aware of this situation and taking measures for improvement will people be able to protect their health and create better conditions for future generations.

Air Pollution Essay for Students in English: 100, 200 and 500 Words

Air pollution is becoming a serious issue that’s affecting human health, flora and fauna and overall well-being of Earth. As responsible citizens of the world, it’s our duty to take care of anything that’s harming the planet and leave it in better condition for future generations. Here are a few sample essays children can use to write about air pollution and learn about different ways to mitigate this crisis.

Air Pollution Essay for Students in English: 100, 200 and 500 Words

Any physical, chemical, or biological alteration in the air is referred to as air pollution. The atmosphere contains a specific portion of the gas. It is harmful to survival to change the makeup of these gases. “Global warming” is the term used to describe the rise in global temperature caused by this imbalance in gas composition. Hazardous pollutants, whether present naturally or artificially, can modify the environment and have a negative impact on the ecosystem. Ineffective resource management and reckless human activity are harming the environment and therefore it is our responsibility as inhabitants of Earth to take care of it.

Pollution is any activity that tampers with the environment's fundamental characteristics and causes damage. The air we breathe is no longer clean and fresh, it has been contaminated by pollutants. The threat to Earth and its ecosystem is getting worse as a result of the contamination of the air, water, and soil. These pollutants are causing a number of respiratory and cardiovascular diseases—our immune system is getting affected negatively, and children are at a high risk of developing asthma and other breathing problems. There are numerous factors that frequently increase this air pollution. Automobiles, transportation methods, industrialization, expanding cities, etc. are the main causes of air pollution. The contamination of the entire atmosphere is brought on by the release of various toxic gases or dangerous components from such sources.

Air pollution, which has a negative impact on the environment, also has a significant impact on the ozone layer. The primary contributor to pollution is the ever-increasing demands of the human population. Daily human activities pump harmful chemicals into the atmosphere, making it more polluted than ever and accelerating climate change. The flora and fauna are also being severely impacted by the airborne harmful chemical releases. The rising contamination of the Earth's air, water, and soil—the essential life support systems of the planet—poses a major threat to the planet and its environment.

One of today's top environmental concerns is air pollution. There are numerous factors that frequently increase this air pollution. Toxic gases, particulates, paint, and batteries containing lead are released throughout the industrialization process. The ozone layer is also being destroyed and the world is being exposed to dangerous solar rays as a result of all the contaminants in touch with the atmosphere.

Ozone is a contaminant that exists at the ground level and can be harmful to human health. But the same ozone creates a layer of defence in the stratosphere. The "good" ozone, however, is being destroyed by ozone-depleting substances—such as hydrochlorofluorocarbons, and chlorofluorocarbons. These chemicals were once used in coolants, foaming agents, insecticides, solvents, and fire extinguishers and occasionally still are.

Primary and secondary pollutants are the two categories that have emerged as a result of the growing number of air pollutants. Primary pollutants, which include smoke, ash, dust, fumes, mist, spray, inorganic gases, carbon dioxide, carbon monoxide, and radioactive substances, have a direct negative impact on fresh air. Secondary pollutants are those that interact chemically with primary pollutants, as well as other elements in the atmosphere, such as sulphate trioxide, ozone, hydrocarbons, and nitrogen dioxide.

Causes of Air Pollution

The disposal of solid wastes that release methane gas and the breakdown of trash landfills are major sources of air pollution. This problem has become a severe environmental and health issue as a result of the population's rapid development, industrialisation, and greater use of cars, planes, and other transportation.

Common Effects of Air Pollution

Pollutants in the air we breathe every minute enter our bloodstream and travel to our lungs and entire body, producing a plethora of health issues. Animals can have health issues similar to people if they are exposed to air toxics in high enough quantities over an extended period of time. Air toxics also play a role in animal sickness, infertility, and birth abnormalities. Therefore, both directly and indirectly, pollution of the environment harms both plants, animals, and people.

What Can We Do

Using public transportation is a surefire short method to reduce air pollution because it uses less gas and electricity, even carpools help with the situation. A permanent, non-polluting, and extremely secure source of energy is the sun or solar power. Solar panels, which are special in design and simple to install, are also a technical benefit to society and the planet. They take in solar energy and store it to power various equipment and electronics. Another step you can take on this path is to plant more trees and live a simplistic life. Minimalist living is not only a trendy millennial lifestyle, but it also has significant societal and environmental benefits.

Air pollution may reach one million tonnes annually in the next decades if environmental protection measures are not taken seriously and effectively enforced. We need to drastically alter our everyday routines if we want to lower the level of air pollution. By making better use of raw materials, water energy, and other resources, we can reduce pollution. Human health can be safeguarded and economic wellbeing can be increased when less harmful compounds are exchanged for hazardous ones.

How big a problem is air pollution globally?

Air pollution is the world’s leading environmental cause of illness and premature death. Fine air pollution particles or aerosols, also known as fine particulate matter or PM 2.5 , are responsible for 6.4 million deaths every year, caused by diseases such as ischemic heart disease, stroke, lung cancer, chronic obstructive pulmonary disease, pneumonia, type 2 diabetes, and neonatal disorders. About 95% of these deaths occur in developing countries, where billions of people are exposed to outdoor and indoor concentrations of PM 2.5 that are multiple times higher than guidelines established by the World Health Organization. A World Bank report estimated that the cost of the health damage caused by air pollution amounts to $8.1 trillion a year, equivalent to 6.1% of global GDP.

Poor people, elderly people, and young children who come from poor families are the most affected and the least likely to be able to cope with the health impacts that come with air pollution. Global health crises such as the COVID-19 pandemic weaken the resilience of societies. Compounding this, exposure to air pollution is linked to increased incidence of COVID-19-related hospital admissions and mortality. In addition to health, air pollution is also linked to biodiversity and ecosystem loss , and has adverse impacts on human capital . Reducing air pollution, on the other hand, not only improves health but strengthens economies. A recent World Bank study found that a 20% decrease in PM 2.5 concentration is associated with a 16% increase in employment growth rate and a 33% increase in labor productivity growth rate .

A World Bank report estimated that the cost of the health damage caused by air pollution amounts to $8.1 trillion a year, equivalent to 6.1% of global GDP.

How is air pollution related to climate change?

Air pollution and climate change are two sides of the same coin, but they are typically addressed separately. They should be tackled jointly, with a focus on protecting peoples’ health – particularly in low- and middle-income countries – to strengthen human capital and reduce poverty.

Air pollutants and greenhouse gases often come from the same sources, such as coal-fired power plants and diesel-fueled vehicles. Some air pollutants do not last long in the environment, notably black carbon – a part of fine particulate matter (PM 2.5 ). Other short-lived climate pollutants (SLCPs) include methane, hydrofluorocarbons, and ground-level or tropospheric ozone. SLCPs are far more potent climate warmers than carbon dioxide. Methane is a precursor of ground-level ozone, which according to the Climate and Clean air Coalition and Stockholm Environment Institute, kills about a million people each year, and is 80 times more potent at warming the planet than carbon dioxide over a 20-year period. Their relatively short lifespans, coupled with their strong warming potential, means that interventions to reduce SLCP emissions can deliver climate benefits in a relatively short time. If we address short-lived climate pollutants, we gain dual benefits: better air quality and improved health where we live, and the global benefit of mitigating climate change.

A World Bank study found that PM 2.5 from the burning of fossil fuels such as coal combustion or diesel-fueled vehicle emissions is among the most toxic types of PM 2.5 . Particles from these sources are more damaging to health than particles from most other air pollution sources. Addressing these sources of PM 2.5 -- like coal combustion and traffic – would address the most toxic air pollution. Given that these sources are also key contributors to climate warming, tackling air pollution from these sources also mitigates climate change.  

What are some requirements for effectively addressing air pollution?

Measure it and monitor it . Many developing countries do not have even rudimentary infrastructure for measuring air pollution. A World Bank study found that there was only one PM 2.5 ground-level monitor per 65 million people in low-income countries , and one per 28 million people in Sub-Saharan Africa;  in contrast, there is one monitor per 370,000 people in high-income countries. This is a serious issue, because you cannot properly manage what you do not measure. If you don't know how bad your problem is, you won’t know whether anything you do to fix it is effective. Countries need to establish ground-level monitoring networks and operate and maintain them properly so they yield reliable air quality data.

Know the main sources of air pollution and their contributions to poor air quality. For example, in City A, transport may be the biggest contributor, but in City B, it could be something completely different, such as emissions from dirty cooking fuels seeping from homes into the outside environment. With this information you can target interventions appropriately to abate air pollution. There are certainly intuitive, no-regret steps cities and countries can take to tackle air pollution, such as shifting to clean buses or renewable energy. But if you want to address air pollution comprehensively, you need to understand what your own sources are.

Disseminate air quality data to the public . People have a right to know the quality of the air they're breathing. Disseminating this information exerts pressure on those who can make the needed changes. Air quality data should be easily accessible in formats that are widely understood so people can reduce their exposure to air pollution and protect vulnerable groups such as young children, the elderly, and people with health conditions that can be exacerbated by poor air quality.

What are some interventions that countries can implement to reduce air pollution?

Reducing air pollution may require physical investments or it may require policy reforms or both. Not every intervention fits every context. Interventions whose benefits (notably improved health) outweigh the costs should be selected. Part of our work at the World Bank is to incorporate climate change considerations into analysis so that the climate benefits of improving air quality can be taken into account in the decision-making process. A few examples of interventions to improve air quality in different sectors:

  • Energy : Change the energy mix to include cleaner, renewable energy sources and phase out subsidies that promote use of polluting fuels.
  • Industry: Use renewable fuels, adopt cleaner production measures, and install scrubbers and electrostatic precipitators in industrial facilities to filter particulates from emissions before they are released into the air.
  • Transport : Change from diesel to electric vehicles, install catalytic converters in vehicles to reduce toxicity of emissions, establish vehicle inspection and maintenance programs.
  • Agriculture : Discourage use of nitrogen-based fertilizers; improve nitrogen-use efficiency of agricultural soils; and improve fertilizer and manure management. Nitrogen-based fertilizers release ammonia, a precursor of secondary PM 2.5 formation. Nitrogen-based fertilizers can also be oxidized and emitted to the air as nitrous oxide, a long-lived greenhouse gas.
  • Cooking and heating : Promote clean cooking and heating solutions including clean stoves and boilers.
Part of our work at the World Bank is to incorporate climate change considerations into analysis so that the climate benefits of improving air quality can be taken into account in the decision-making process.

What is the World Bank doing to help?

The World Bank has invested about $52 billion in addressing pollution in the past two decades. However, we need to scale this up. Some successful projects that address air pollution include:

In China , we supported a program in the Hebei region , the largest contributor to air pollution in the country. The overall result was a reduction in the concentration of PM 2.5 in the atmosphere by almost 40% between 2013 and the end of 2017. The program linked loan disbursements to tangible results. Hebei issued the most stringent industrial emission standards in the country, replaced diesel buses with electric buses, coal stoves with gas stoves, and improved the efficiency of fertilizer use in agriculture. The program also supported effective use of a continuous emission monitoring system to track and enforce compliance by all major industrial enterprises in the province. The project delivered about 5 million tons of CO2 equivalent emissions reductions per year through interventions such as the installation of new stoves in municipalities, and addition of a new clean energy bus fleet. The emissions reductions generated from the installation of 1,221,500 new stoves alone were equivalent to taking more than 860,000 passenger cars off the road each year.

In Peru , the World Bank is supporting a project to develop environmental information systems that includes expanding the country's air quality monitoring network to six new cities. The project is also developing new systems to disseminate information on environmental quality to the public.

In Egypt, we assessed the health impacts from environmental pollution, including the effects of ambient air pollution in Greater Cairo. We found that 19,200 people died prematurely and over 3 billion days were lived with illness in Egypt in 2017 as a result of PM 2.5 air pollution in Greater Cairo and inadequate water, sanitation, and hygiene in all of Egypt. This analytical work has led to a project to reduce vehicle emissions, improve the management of solid waste, and strengthen the air and climate decision-making system in Greater Cairo .

In Vietnam , we are working with the rapidly growing city of Hanoi to simultaneously combat the issues of climate change and air pollution. We are supporting the Ministry of Environment and Natural Resources to improve the Air Quality Monitoring Network and develop an understanding of emissions sources, as well as an Air Quality Management Plan for the city.

In Lao PDR , the World Bank program supported the government in establishing stringent ambient air quality standards, including a standard for annual average concentrations of PM 2. in line with the World Health Organization’s air quality guideline value at the time. The program also supported the adoption of regulated procedures for sampling and analyzing PM 2.5 and PM 10 in air, and other pollutants in water.

We need to tackle air pollution and climate change challenges jointly rather than separately with a focus on protecting peoples’ health today, particularly in developing countries.

Can we expect better air quality in the future as countries decarbonize their economies?

First, we must continue to reduce poverty and meet the needs of poor people, whether through lower energy costs, ensuring cleaner air, or other means. With these goals in mind, we need to tackle air pollution and climate change challenges jointly rather than separately with a focus on protecting peoples’ health today, particularly in developing countries. The health benefits of reducing emissions from the burning of fossil fuels can occur in the near term. However, the reduction of carbon dioxide in the atmosphere would occur over a longer timeframe. If decarbonization efforts pay attention to non-CO 2 pollutants as well, notably PM 2.5 , we cannot only expect better air quality, but also health benefits in the short term.

Effects of Pollution

Pollution affects the quality of life more than one can imagine. It works in mysterious ways, sometimes which cannot be seen by the naked eye. However, it is very much present in the environment. For instance, you might not be able to see the natural gases present in the air, but they are still there. Similarly, the pollutants which are messing up the air and increasing the levels of carbon dioxide is very dangerous for humans. Increased level of carbon dioxide will lead to global warming .

Further, the water is polluted in the name of industrial development, religious practices and more will cause a shortage of drinking water. Without water, human life is not possible. Moreover, the way waste is dumped on the land eventually ends up in the soil and turns toxic. If land pollution keeps on happening at this rate, we won’t have fertile soil to grow our crops on. Therefore, serious measures must be taken to reduce pollution to the core.

How to Reduce Pollution?

After learning the harmful effects of pollution, one must get on the task of preventing or reducing pollution as soon as possible. To reduce air pollution, people should take public transport or carpool to reduce vehicular smoke. While it may be hard, avoiding firecrackers at festivals and celebrations can also cut down on air and noise pollution. Above all, we must adopt the habit of recycling. All the used plastic ends up in the oceans and land, which pollutes them.

So, remember to not dispose of them off after use, rather reuse them as long as you can. We must also encourage everyone to plant more trees which will absorb the harmful gases and make the air cleaner. When talking on a bigger level, the government must limit the usage of fertilizers to maintain the soil’s fertility. In addition, industries must be banned from dumping their waste into oceans and rivers, causing water pollution.

To sum it up, all types of pollution is hazardous and comes with grave consequences. Everyone must take a step towards change ranging from individuals to the industries. As tackling this problem calls for a joint effort, so we must join hands now. Moreover, the innocent lives of animals are being lost because of such human activities. So, all of us must take a stand and become a voice for the unheard in order to make this earth pollution-free.

I Hate Summer—and You Should Too

Sunburned boy

W ake me when it’s over—summer, that is. I know, I know, you just love it: the long days, the warm evenings, the trips to the beach, the afternoons at the ballpark when your favorite team is playing and the pennant race is tightening—and the temperature is skyrocketing, and your skin is blistering, and the beer is $6, and the drive home will be in 88° heat, which is fine if you don’t mind running the air conditioner, except that you’re burning through $4–a-gallon gas, because it’s summer-driving season and the giant oil companies didn’t get to be the giant oil companies without knowing the right time of year to hike their prices. 

And that’s hardly all of it. Summertime is the season of horribles, from higher crime rates, to increased warfare, to spikes in asthma, to raging wildfires, to swarms of bugs, to a rise in traffic accidents—and even to a bump in divorces, because how could a 100° heat wave, a busted A.C., and the kids out of school not spell domestic bliss?

What’s more, it’s only getting worse. Last summer was the hottest on record, according to the National Oceanic and Atmospheric Administration, and the 10 warmest years were all from 2010 to 2022. So with a lousy part of the year becoming lousier still, here, in no particular order, are nine reasons summer is the suckiest season of them all.

Road wrecks

There’s nothing like long days, no school, and lots of teen drivers to make the highways a safe place to be. Not . It’s no coincidence that the Automobile Association of America (AAA) labels the stretch between Memorial Day and Labor Day “the 100 deadliest days.” There are over 11.7 million U.S. drivers between the ages of 15 and 20, and if you know what’s good for you you’ll stay out of their way—especially when they’re out as a group, driving recreationally. “We know that when teens are joyriding as opposed to driving with a specific destination and time in mind, there is a heightened risk,” said Diana Gugliotta, senior manager of public affairs for AAA Northeast, in a statement last year.

AAA’s numbers back that up. When a teen driver has only other teens in a vehicle, the risk of fatality for the driver and all passengers increases 51%. When at least one passenger is over 35, the overall fatality risk declines 8%. From 2011 to 2020, there were 7,316 deaths in summertime teen-related traffic accidents—nearly half the total of all teen-related traffic accidents for the year.

This means war

Napoleon Bonaparte could tell you a thing or two about what it’s like to pick a fight with Russia in the dead of winter. In 1812, the French army suffered half a million casualties in battles that climaxed in December—a rout that led to Napoleon’s abdication and exile in 1815. Any general worth his steed would prefer to fight in the summer when there’s plenty of light, the roads are clear, and soldiers aren’t bundled up against the cold. As far back as 55 BCE , the Roman army’s “campaigning season” would end when summer wound down and the soldiers would retreat to their winter quarters. It’s probably not a coincidence that World War I began in August 1914, World War II on Sept. 1, 1939, and Nazi Germany’s invasion of Russia in June 1941. More recently , in August 1990, Iraq invaded Kuwait, and in August 1991, the old Soviet Union nearly fell into civil war when communist hardliners tried to oust President Mikhail Gorbachev. America’s 20-year war in Afghanistan typically saw its fiercest fighting in the summer months, and the same is true of the war in Ukraine .

Hot-weather warfare is likely only to get worse. A 2009 paper in PNAS found that rising temperatures exacerbated by climate change could lead to a 54% increase in the risk of civil war in Africa by 2030. A 2011 study in Nature found that warmer weather during El Niño years doubled the risk of civil war in 90 tropical countries and could have accounted for 20% of conflicts around the world over the past half century. Meantime, what’s the season of peace on Earth and goodwill toward men? Wintertime, baby. Wintertime.

Going buggy

Summer advertises itself as the season of birdsong and butterflies. Don’t believe it. It’s the season of pests—particularly ticks, mosquitoes, flies, fleas, bees, and wasps. Ticks, mosquitoes, and fleas in particular can spread diseases that include malaria, yellow fever, Zika, dengue, Lyme, and chikungunya. Bees, wasps, and yellowjackets—with their infernal stings—are similarly creatures of the summer. And you think you know flies? You don’t know flies. There are 110,000 species of them —most more active in hot weather—making up a global population of 17 million flies for every living human. Pssst ! They’ve got us surrounded.

Season of wheeze

Ah, summer, it takes your breath away. Literally. More than 25 million Americans have asthma, and 4.7 million of them are children— according to the U.S. Centers for Disease Control and Prevention (CDC). If that means suffering during the temperate months, it’s much worse when the oven that is summer turns the dial up to broil. Heat and humidity constrict and narrow airways , trap ozone, and cause the air to entrain more particulate matter from cars, trucks, and smokestacks. What’s more, stagnant summer air—especially in homes with poor air conditioning or none at all—can exacerbate the presence of mold, dust, and pollen. And then—and stop me if I’ve mentioned this before—climate change is making things more punishing still for people with asthma. A 2023 U.S. Environmental Protection Agency report found that rising temperatures could increase the incidence of childhood asthma by anywhere from 4% to 11%, due partly to worsening pollution and allergies, and the growing problem of wildfire smoke .

Speaking of wildfires…

When it comes to dust, haze, and a mustard-colored sky, Mars has got nothing on Earth—at least during the summer fire season. Last year’s Canadian wildfires , sparked by lightning and fueled by high temperatures and drought, torched more than 71,000 square miles of land in Canada—an area the size of North Dakota—and yellowed out skies in the U.S. from the Midwest to the Northeast to the mid-Atlantic states. But the U.S. is playing with matches too. California’s wildfire season runs from April through October—peaking in the summer—with megadroughts and heat waves driving the flames. Of the state’s 20 largest fires, half occurred from 2017 to 2022. Climate change, of course, plays a regrettable role in all of this.

Crime and punishment

Nothing puts bad guys in a bad mood like hot weather—or so it seems. A 2019 study by the National Bureau of Economic Research found that on days with a maximum temperature above 85°F, all crime increases by 2.2% and violent crime by 5.7%. A 2023 study in PLOS One attributed this to what is known as the Theory of Routine Activities, which postulates that for crime to occur, three factors must be present: a motivated offender, a suitable target, and an absence of guards or surveillance. Of these, it is the second one—the suitable target—that is especially common in summer, according to the 2023 study, with greater numbers of people out on the streets. 

As for the first variable, a motivated offender, well, even criminals don’t   want to be outside commiting a crime in a 20°-below polar vortex. During a particularly deep freeze in 2015, Boston saw a 32% drop in burglaries, a 35% drop in larceny, and 46% drop in vehicle theft. Over the same period, New York City set a modern-day record , going 12 days without a homicide.

Summer’s contribution to violent crime in particular may be due at least in part to the common experience of hot weather leading to hot tempers, with even the most even-keeled people more inclined to blow a seam if they can’t cool off. One 2020 study found that people playing competitive video games in a hot room were more aggressive toward their gaming partner than they were when the room was cooler.

Daylight Saving Time

Don’t get me started on Daylight Saving Time. There is just nothing to like about this spring-forward inanity. For starters, it increases energy consumption (when it was supposed to decrease it) due to greater use of air conditioning. The changes in sleep patterns it causes contribute to heart attack , stroke , inflammation , and suicide , not to mention a 6% increase in fatal traffic accidents due to circadian scrambling and overall sleepiness. Small children and teens suffer particularly when the change in the clocks affects sleep cycles.

Finally, the atmospherics are all wrong. Nighttime is nighttime, people; the sun is the party guest that won’t go home if it’s still out at 9 p.m. I say send it packing no later than 8 p.m. and then race back to a nice wintertime sundown at cocktail hour. Cheers.

Trouble on the homefront

If you want to stay married, it might be wise to sleep through summer. That’s the finding of a 2016 study out of the University of Washington showing that August, along with March, are the two peak months for divorce in the U.S. The reason in both cases is more or less the same: couples tend to see winter and summer vacations as untouchable family time and, even in highly stressed marriages, will make it a point to hold the ship together for those treasured stretches. Once the good times are over, however, the marriages might be too.

“People tend to face the holidays with rising expectations, despite what disappointments they might have had in years past,” said sociology professor and the study’s co-author Julie Brines, in a statement at the time the research was released. “They’re very symbolically charged moments in time.”

When those expectations are dashed, a bust-up is likelier to follow. And while both early spring and late summer were implicated equally in that study, other research by Stowe Family Law in the U.K. found that September—the tail end of summer—is the peak divorce month on the other side of the pond, with total-immersion family time throwing financial, interpersonal, and other issues into relief. 

It kills your skin

No matter how good it might feel to bake in the sun, your skin really, truly does not want a tan. In a rapidly warming world, it should come as no surprise that the sun is murder on your skin—drying it, aging it, cracking it, and much more importantly, leading to cancer. A 2022 paper in the journal Cureus found the highest rates of skin cancer diagnoses occurring from July to October. 

Simple steps like wearing sunscreen , avoiding the sun from 10 a.m. to 4 p.m., and wearing protective clothing can all help reduce the risk. Sunshine in the winter, of course, can cause similar damage, but in the summer you're out a whole lot more and wearing a whole lot less. That—like summer as a whole—spells trouble.

Correction: The original version of this story misstated the date of Napoleon Bonaparte's abdication. It was 1815, not 1914.

Phoenix Continues To Suffer Through Its Worst Heat Wave On Record

2023 set a record for U.S. heat deaths. Why 2024 could be even deadlier

David Hom suffered from diabetes and felt nauseated before he went out to hang his laundry in 108-degree weather, another day in Arizona’s record-smashing, unrelenting July heat wave.

His family found the 73-year-old lying on the ground, his lower body burned. Hom died at the hospital, his core body temperature at 107 degrees.

WATCH NOW: Why extreme heat is more dangerous than many realize

The death certificates of more than 2,300 people who died in the United States last summer mention the effects of excessive heat, the highest number in 45 years of records, according to an Associated Press analysis of Centers for Disease Control and Prevention data. With May already breaking heat records, 2024 could be even deadlier.

And more than two dozen doctors, public health experts, and meteorologists told the AP that last year’s figure was only a fraction of the real death toll . Coroner, hospital, ambulance and weather records show America’s heat and health problem at an entirely new level.

“We can be confident saying that 2023 was the worst year we’ve had from since … we’ve started having reliable reporting on that,” said Dr. John Balbus, director of the Office of Climate Change and Health Equity at the Department of Health and Human Services.

Last year, ambulances were dispatched tens of thousands of times after people dropped from the heat. It was relentless and didn’t give people a break, especially at night. The heat of 2023 kept coming, and people kept dying.

“It’s people that live the hot life. These are the ones who are dying. People who work outside, people that can’t air-condition their house,” said Texas A&M climate scientist Andrew Dessler, who was in hard-hit southern Texas. “It’s really quite, quite grim.”

Dallas postal worker Eugene Gates Jr., loved working outdoors and at 7:30 a.m. June 20, the 66-year-old texted his wife that it was close to 90 degrees. He kept working in the heat that felt like 119 degrees with the humidity factored in and finally passed out in somebody’s yard. He ran a fever of 104.6 degrees and died, with the medical examiner saying heat contributed to his death.

“The way that my husband died, it could have been prevented,” said Carla Gates.

“There’s just very low awareness that heat kills. It’s the silent killer,” said University of Washington public health scientist Kristie Ebi, who helped write a United Nations special report on extreme weather. That 2012 report warned of future dangerous heat waves.

Ebi said in the last few years, the heat “seems like it’s coming faster. It seems like it’s more severe than we expected.”

DEATHS DOWN SOUTH

Last summer’s heat wave killed differently than past ones that triggered mass deaths in northern cities where people weren’t used to the high temperatures and air conditioning wasn’t common. Several hundreds died in the Pacific Northwest in 2021, in Philadelphia in 1998 and in Chicago in 1995.

Nearly three-quarters of the heat deaths last summer were in five southern states that were supposed to be used to the heat and planned for it. Except this time they couldn’t handle it, and it killed 874 people in Arizona, 450 in Texas, 226 in Nevada, 84 in Florida and 83 in Louisiana.

Those five states accounted for 61% of the nation’s heat deaths in the last five years, skyrocketing past their 18% share of U.S. deaths from 1979 to 1999.

At least 645 people were killed by the heat in Maricopa County, Arizona, alone, according to the medical examiner’s office. People were dying in their cars and especially on the streets, where homelessness, drug abuse and mental illness made matters worse.

Three months after being evicted from her home, 64-year-old Diana Smith was found dead in the back of her car. Her cause of death was methamphetamine and fentanyl, worsened by heat exposure, Phoenix’s medical examiner ruled.

“In the last five years, we are seeing this consistent and record kind of unprecedented upward trend. And I think it’s because the levels of heat that we have seen in the last several years have exceeded what we had seen in the last 20 or 30,” said Balbus, of the Office of Climate Change and Health Equity at the Department of Health and Human Services.

UNRELENTING HEAT

Phoenix saw 20 consecutive days of extreme heat stress in July, the longest run of such dangerously hot days in the city since at least 1940, according to the data from the Copernicus Climate Change Service. Phoenix wasn’t alone.

Last year the U.S. had the most heat waves since 1936. In the South and Southwest, Last year was the worst on record, according to the National Oceanic and Atmospheric Administration.

“It was crazy,” said University of Miami tropical meteorology researcher Brian McNoldy, who spent the summer documenting how Miami broke its daily heat index record 40% of the days between mid-June and mid-October.

Houston’s Hobby airport broke daily high temperature marks 43 times, meteorologists said. Nighttime lows set records for heat 57 times, they said. That didn’t give people’s bodies chances to recover.

Across five southern states, the average rate of emergency department visits for heat illness in the summer of 2023 was over double that of the previous five summers, according to an analysis of data from the CDC.

Experts warned that counting heat mortality based on death certificates leads to underestimates. Heat illness can be missed, or might not be mentioned.

They pointed to “excess death” studies for a more realistic count. These are the type of long-accepted epidemiological studies that look at grand totals of deaths during unusual conditions — such as hot days, high air pollution or a spreading COVID-19 pandemic — and compare them to normal times, creating an expected trend line.

Texas A&M’s Dessler and his colleague Jangho Lee published one such study early last year. According to their methods, Lee said, about 11,000 heat deaths likely occurred in 2023 in the U.S. — a figure that would represent a record since at least 1987 and is about five times the number reported on death certificates.

Deaths are also up because of better reporting, and because Americans are getting older and more vulnerable to heat, Lee said. The population is also slowly shifting to cities, which are more exposed to heat.

In some places, last year’s heat already rivals the worst on record. As of late May, Miami was on track to be 1.5 degrees warmer than the hottest May on record, according to McNoldy. Dallas’ Murphy pointed to maps saying conditions with a broiling Mexico are “eerily similar to what we saw last June” so he is worried about “a very brutal summer.”

Texas A&M’s Dessler said last year’s heat was “a taste of the future.”

“I just think in 20 years, you know, 2040 rolls around … we’re going to look back at 2023 and say, man, that was cool,” Dessler said. “The problem with climate change is if if it hasn’t pushed you over the edge yet, just wait.” ___ Borenstein reported from Washington, Wildeman from Hartford, Connecticut, and Snow from Phoenix. Kendria LaFleur contributed from Dallas.

Crafting Persuasive Narratives: the Art of Influence through Reason, Emotion, and Credibility

This essay about the art of persuasion explores the interplay of logos, pathos, and ethos in crafting compelling narratives. It illustrates how these three elements—reason, emotion, and credibility—intersect to sway opinions, inspire action, and shape discourse. Through examples spanning renewable energy advocacy, humanitarian appeals, and public health campaigns, the essay demonstrates how communicators strategically leverage these modes of persuasion to make logical arguments, evoke emotional responses, and establish credibility. Ultimately, it highlights the importance of integrating these elements harmoniously to create persuasive narratives that resonate with audiences and drive meaningful change.

How it works

In the realm of communication and discourse, the art of persuasion reigns supreme, employing a trifecta of strategies to sway opinions, inspire action, and shape narratives. At the heart of this art lie three pillars: logos, the appeal to reason and logic; pathos, the appeal to emotions; and ethos, the appeal to credibility and authority. By understanding and mastering these elements, communicators wield a powerful arsenal for crafting narratives that captivate, convince, and compel.

Let’s embark on a journey through the annals of persuasion, exploring how these three modes intersect and intertwine to form cohesive and compelling arguments.

Imagine, if you will, a world where renewable energy reigns supreme, where the air is clean, and the future is bright. In this world, the persuasive power of logos is on full display, as advocates present irrefutable evidence and compelling statistics to support the transition to sustainable energy sources. From plummeting carbon emissions to burgeoning job markets in the renewable sector, the logical case for embracing clean energy is clear and convincing.

Yet, in the realm of persuasion, logic alone is not enough. Enter pathos, the emotional undercurrent that tugs at heartstrings and stirs the soul. Picture a humanitarian crisis unfolding on distant shores, where lives hang in the balance and hope hangs by a thread. Here, the power of pathos is palpable, as storytellers weave tales of resilience, compassion, and human suffering. Through vivid imagery, poignant anecdotes, and raw emotion, they bridge the gap between empathy and action, compelling audiences to lend a helping hand and make a difference in the world.

But persuasion is not merely a matter of facts and feelings; it is also a matter of trust and credibility. Consider the case of a renowned expert in their field, a paragon of knowledge and integrity. As they take the stage to address a captive audience, their ethos precedes them, commanding respect and instilling confidence. With every word they speak and every argument they make, they bolster their credibility, establishing themselves as authorities worthy of trust and admiration. Whether in the courtroom, the boardroom, or the public square, ethos serves as a bedrock of persuasion, grounding arguments in the solid foundation of expertise and integrity.

Moreover, the true power of persuasion lies in the seamless integration of logos, pathos, and ethos, each element complementing and reinforcing the others to create a symphony of persuasion. Picture a political campaign rallying supporters to the polls, its message resonating with equal parts reason, emotion, and authority. Through a combination of compelling policy proposals, stirring speeches, and endorsements from trusted leaders, the campaign galvanizes voters and shapes the course of history.

In the realm of public health, persuasion takes on a life-saving urgency, as advocates strive to combat misinformation and promote vaccination against deadly diseases. Here, logos takes center stage, as scientists and healthcare professionals present rigorous evidence and sound reasoning in support of immunization. Yet, in the face of vaccine hesitancy and skepticism, pathos emerges as a potent force, appealing to parents’ fears for their children’s health and safety. Meanwhile, the credibility of medical experts and public health authorities serves as a bulwark against doubt and distrust, reinforcing the message of vaccination as a critical tool for protecting individual and community well-being.

In conclusion, the art of persuasion is a multifaceted and dynamic endeavor, requiring a deft touch and a keen understanding of human nature. By harnessing the power of logos, pathos, and ethos, communicators can forge connections, change minds, and shape the course of history. Whether advocating for social change, marketing a product, or mobilizing support for a cause, the principles of persuasion remain constant, guiding us on a journey of discovery, influence, and impact.
