What You'll Learn
Fossil fuel combustion
In the United States, air pollution from all sources, including fossil fuel combustion, has had a significant impact on public health. While estimates vary, studies suggest that air pollution contributes to tens of thousands of deaths in the country each year. According to a 2019 report, approximately 107,000 Americans die annually from heart attacks, strokes, and other illnesses caused by air pollution from factories, motor vehicles, and agricultural activities. More recently, in 2021, an estimated 63,600 deaths in the United States were attributed to air pollution.
The combustion of fossil fuels, such as coal, oil, gasoline, diesel, and natural gas, releases fine particulate matter (PM 2.5) and toxic air pollutants, including carbon dioxide (CO2). These pollutants have been associated with premature deaths and various health issues, particularly in vulnerable populations such as children and low-income communities. According to research by Harvard University and other institutions, fossil fuel pollution led to more than 8 million deaths worldwide in 2018, accounting for about 1 in 5 deaths globally.
The impact of fossil fuel combustion on children's health is of particular concern. Thousands of children under the age of five die each year from respiratory infections attributed to fossil fuel pollution. Additionally, children, especially those from poorer backgrounds, bear a disproportionate burden of disease and developmental impairments due to environmental pollution and climate change caused by fossil fuel combustion. The economic costs of the health impacts of fossil fuel combustion are also significant, with estimates of avoided health costs attributed to pollution and climate change being staggering.
To mitigate the health and environmental impacts of fossil fuel combustion, a transition to alternative energy sources and cleaner technologies is necessary. Leading organizations, such as the International Energy Agency (IEA), emphasize the availability of technologies that can significantly reduce air pollution levels and provide economic benefits. Businesses can play a crucial role by reducing emissions, increasing energy efficiency, and adopting renewable energy sources. Additionally, individuals can contribute by conserving energy, minimizing vehicle usage, and supporting initiatives for sustainable land use, cleaner energy, and improved waste management.

Agriculture
In the United States, air pollution is responsible for approximately 100,000 deaths per year, according to a 2019 study published in the Proceedings of the National Academy of Sciences. This figure includes fatalities caused by fine particulate matter known as PM2.5, which is released from factories, motor vehicles, and farmland. While pollution from power plants, factories, and vehicles is regulated under the Clean Air Act, there is less oversight of air quality around farms.
A 2021 study published in the Proceedings of the National Academy of Sciences attributed 17,900 annual deaths in the United States to pollution from farms, with 89 of those deaths linked to hog emissions in Duplin County. Animal agriculture, which includes beef, pork, and dairy facilities, is the worst emitter, responsible for 80% of deaths from pollution related to food production. Gases and lung-irritating particles associated with manure, animal feed, and fertilizer can drift for hundreds of miles, affecting communities far from the source of pollution.
Ammonia emissions from animal waste stored in massive "lagoons" and nitrogen-rich liquid waste sprayed on farm fields contribute significantly to air pollution. Hill, an expert in this field, states that agriculture is responsible for 15% of deaths from reduced air quality. Per serving, the rate of air-pollution deaths linked to red meat was twice as high as that of eggs, three times as high as that of dairy, and at least 15 times as high as that of fruits and vegetables.
To reduce air pollution from agriculture, sustainable farming practices and a reduction in meat consumption have been suggested. Additionally, implementing policies that support sustainable land use, cleaner energy sources, and improved waste management practices can help mitigate air pollution and its associated health risks.

Non-fossil fuel combustion
Air pollution is a serious issue in the United States, contributing to an estimated 63,600 deaths in 2021. While fossil fuel combustion is a significant contributor to air pollution, it is important to also consider non-fossil fuel combustion sources. These can include various human activities and industries that release pollutants into the atmosphere, causing adverse health effects and mortality.
Household Combustion Devices
The use of household combustion devices, such as stoves, fireplaces, and heaters, can release pollutants into the air. Incomplete combustion of solid fuels, such as wood or coal, can lead to the emission of harmful pollutants like carbon monoxide, particulate matter, and volatile organic compounds. These emissions can have detrimental effects on indoor and outdoor air quality, particularly in poorly ventilated spaces.
Agricultural Activities
Agricultural practices contribute significantly to air pollution through various means, including the use of combustion engines in farm equipment, the burning of crop residues, and the application of fertilizers and pesticides. According to a study, agriculture is responsible for 15% of deaths from reduced air quality in the United States. Ammonia, a nitrogen compound emitted primarily from agricultural activities, can contribute to the formation of particulate matter and secondary pollutants, affecting both local and regional air quality.
Wildfires
Wildfires are natural or human-induced fires that burn across wildland areas, releasing smoke and pollutants into the atmosphere. These fires can be started by lightning strikes or human activities, such as unattended campfires or carelessly discarded cigarettes. Wildfires emit carbon monoxide, nitrogen oxides, volatile organic compounds, and particulate matter, which can have detrimental effects on air quality and human health. The impact of wildfires on air pollution can be long-lasting and far-reaching, affecting communities even outside the immediate vicinity of the fire.
Waste Burning and Open Burning Practices
The burning of waste materials, either through open burning or in incinerators, can release toxic pollutants into the air. Open burning of garbage, plastics, and other waste products is a common practice in some regions, releasing harmful chemicals such as dioxins, furans, heavy metals, and particulate matter. Additionally, the incineration of medical waste, electronic waste, and other hazardous materials can lead to the emission of toxic pollutants if not properly controlled.
Addressing non-fossil fuel combustion sources of air pollution is crucial for improving air quality and protecting public health. By implementing sustainable practices, cleaner energy sources, and better waste management strategies, we can mitigate the impact of these sources on the environment and human well-being.
