Air Pollution's Main Culprit: Fossil Fuels' Harmful Impact

Burning fossil fuels releases a cocktail of pollutants into the atmosphere, including carbon dioxide, sulfur dioxide, nitrogen oxides, and particulate matter. These emissions are a major cause of air pollution, which has been linked to a range of health issues, including asthma, cancer, heart disease, and respiratory problems. According to research, air pollution from fossil fuels is responsible for about one in five deaths worldwide, with a recent study putting the number of deaths attributed to fossil fuel pollution at 8.7 million in 2018 alone. The combustion of fossil fuels also contributes to climate change, causing rising global temperatures, extreme weather events, and rising sea levels. The environmental and health impacts of fossil fuel pollution disproportionately affect children, especially those from low-income backgrounds, and communities of color.

Fossil fuel combustion by-products are the greatest threat to children's health

Fossil fuel combustion produces a range of harmful by-products, including toxic air pollutants and carbon dioxide, which contribute to climate change and air pollution. These by-products have been linked to a range of health issues in children, including respiratory infections, asthma, cancer, and heart disease.

Children are more vulnerable to the effects of air pollution than adults due to several factors. Firstly, they breathe more air per kilogram of body weight and require more food relative to their body weight, increasing their exposure to pollutants in the air and food. Secondly, their bodies and brains are still developing, making them more susceptible to the adverse effects of toxic air pollutants and climate change. This includes impaired brain development, which can hinder their ability to learn and affect their future economic productivity and contributions to society.

Socioeconomic inequalities further exacerbate the health risks for children. Poor children bear a disproportionate burden of disease and developmental impairments due to environmental pollution and climate change caused by fossil fuel combustion. Inadequate nutrition, lack of social support, and psychosocial stress associated with poverty can magnify the toxic effects of exposures and climate change on their health.

Additionally, children in developing countries are more vulnerable to the impacts of climate change, such as heat waves and infectious diseases. According to the World Health Organization (WHO), children under five carry more than 40% of the burden of environmentally related diseases and over 88% of the burden of climate change, despite comprising only 10% of the global population.

The combustion of fossil fuels for electricity production, heating, transportation, and industry is the primary source of air pollution. By reducing our dependence on fossil fuels and transitioning to clean energy sources, we can significantly improve children's health and reduce the economic and societal costs associated with fossil fuel combustion by-products.

Fossil fuel air pollution causes premature deaths

Fossil fuels produce hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants are harmful to the environment and human health. Burning fossil fuels like coal, gasoline, and diesel produces significant quantities of PM 2.5, including soot, and fine particulate matter, which can have deadly impacts.

A recent study published in Environmental Research found that air pollution from fossil fuels is responsible for about 8.7 million deaths globally in 2018. This figure is more than twice the previous estimate of 4.2 million and is attributed to the burning of coal, gasoline, and diesel. The study, authored by a team from Harvard University, the University of Birmingham, and the University of Leicester, found that exposure to fine particulate matter, or PM 2.5, from burning fossil fuels contributed to the high number of premature deaths.

The regions with the highest concentrations of fossil fuel-related air pollution, including Eastern North America, Europe, and Southeast Asia, have the highest rates of mortality related to air pollution. In particular, China and India had the highest number of premature deaths, with nearly five million people dying prematurely in these two countries alone due to air pollution. Other hard-hit areas included Western Europe, parts of Southeast Asia, and the U.S. Northeast and Midwest.

The study's authors used GEOS-Chem, a global 3-D computer model of atmospheric chemistry, to analyze the data. They input regional fossil fuel emissions data from various sources, including industry, ships, aircraft, ground transportation, and oil and gas drilling. The scientists then validated their model by checking their emissions data against on-the-ground observations from the World Health Organization. The higher death toll is attributed to the use of a finer spatial scale when analyzing local measures of pollution.

The findings of this study highlight the urgent need to transition to alternative energy sources and reduce the number of needless deaths caused by fossil fuel air pollution.

Fossil fuel combustion releases carbon dioxide, a greenhouse gas

According to the Environmental Protection Agency (EPA) in 2022, CO2 emissions from burning fossil fuels accounted for about 74% of total greenhouse gas emissions in the United States. Globally, the combustion of fossil fuels has severe consequences, including melting glaciers, rising sea levels, and increasing global temperatures. The transportation sector, heavily reliant on petroleum fuels, is a significant contributor to CO2 emissions within the major energy-consuming sectors.

The impact of fossil fuel combustion extends beyond climate change. Air pollution from burning fossil fuels releases hazardous pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants have detrimental effects on both the environment and human health. For example, they contribute to acid rain, eutrophication, damage to crops and forests, and respiratory issues. Additionally, the fine particulate matter (PM 2.5) released during fossil fuel combustion has been linked to approximately 8.7 million premature deaths worldwide in 2018, with a significant impact in countries like China, India, and the United States.

Furthermore, water pollution is another consequence of fossil fuel combustion. Oil spills, fracking fluids, and toxic wastewater contaminate groundwater, drinking water, and oceans, posing threats to wildlife and human communities. The ocean's absorption of CO2 leads to ocean acidification, making it challenging for marine organisms to build shells and coral skeletons. This increased acidity has already impacted coral reefs and various economic sectors, including fishing and tourism.

To address the issues arising from fossil fuel combustion, a transition to renewable and clean energy sources is imperative. Reducing carbon emissions, eliminating fossil fuel subsidies, and implementing policies to mitigate the social cost of carbon are essential steps toward mitigating the environmental and health impacts of fossil fuel combustion and reducing carbon dioxide, a potent greenhouse gas.

Fossil fuel extraction, transportation, and refining can lead to oil spills

Fossil fuels are a major contributor to air pollution, with combustion releasing a range of harmful pollutants into the atmosphere. Carbon dioxide, a greenhouse gas, is the primary driver of global warming, but other byproducts such as sulfur dioxide, nitrogen oxides, and particulate matter also have significant impacts. The burning of coal, gasoline, and diesel has been linked to approximately 8.7 million premature deaths each year, with long-term exposure to air pollution causing even more fatalities.

The extraction, transportation, and refining of fossil fuels carry inherent risks, including the potential for oil spills. Oil spills can occur during any stage of the fossil fuel supply chain where oil is present, including drilling, transportation, and refining. They have detrimental effects on both the environment and local communities. One of the most notable oil spills was the 2010 BP Deepwater Horizon spill in the Gulf of Mexico, which released 134 million gallons of oil, causing the deaths of 11 people and countless animals, including birds, turtles, fish, marine mammals, and plants. The incident also resulted in substantial financial consequences for BP, with penalties and cleanup costs totaling $65 billion.

Oil spills can contaminate soil and water, leading to devastating explosions and fires. They can harm wildlife in two primary ways: fouling or oiling, and oil toxicity. Fouling or oiling occurs when oil physically impairs a plant or animal, such as coating a bird's wings with oil, rendering it unable to fly. Oil toxicity, on the other hand, is caused by the various toxic compounds found in oil, which can lead to severe health issues such as heart damage, stunted growth, and immune system dysfunction, and even death.

The impact of oil spills extends beyond environmental damage. They can ruin recreational activities, such as a day at the beach, and pose risks to human health by making seafood unsafe to eat. The cleanup and recovery process following an oil spill is challenging, especially when dealing with wide spill areas and large animals like whales. Oil spills can also result in the closure of beaches, parks, and fisheries, affecting local economies that depend on these attractions.

To mitigate the risks of oil spills, governments and industries are working together to develop and enforce stricter standards, regulations, and procedures. These include the Oil Pollution Act of 1990, which mandates double-hull construction for new oil tankers operating between U.S. ports, and the establishment of the Bureau of Ocean Energy Management and the Bureau of Safety and Environmental Enforcement to provide enhanced oversight and enforcement of environmental regulations for offshore energy development.

Fossil fuel pollution disproportionately affects minorities and low-income communities

Fossil fuels produce hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants are harmful to both the environment and human health. Air pollution from fossil fuels can cause acid rain, eutrophication, damage to crops and forests, and harm to wildlife. In addition, the burning of fossil fuels releases greenhouse gases, such as carbon dioxide, which contribute to climate change and global temperature increases.

The impacts of fossil fuel pollution disproportionately affect minority and low-income communities. Environmental racism refers to the unequal access to a clean environment and basic environmental resources based on race. Communities of color are more likely to live in areas with heavy pollution and are disproportionately impacted by environmental hazards. For example, in a predominantly Black and low-income area of Louisiana known as "Cancer Alley," the cancer risk is nearly 50 times higher than the national average due to the presence of numerous chemical plants and oil refineries.

Minority and low-income populations are also more likely to reside near industrial facilities, increasing their risk of exposure to chemical spills and toxic leaks. In Baltimore, 60% of African Americans live within one mile of a Toxic Release Industry, and 70% live within two to four miles. Additionally, people of color are more vulnerable to the impacts of climate change, such as heatwaves and extreme weather events.

The fossil fuel industry has been criticized for perpetuating systemic racism by passing the costs of its pollution onto communities of color. Policies that solely focus on reducing greenhouse gas emissions without addressing fossil fuel usage have been accused of failing to mitigate local air and water pollution and perpetuating racially inequitable impacts. Noel Healy, a professor at Salem State University, advocates for a shift in climate policies to focus on the root cause of pollution, which is fossil fuels, and to explicitly include historically targeted communities in climate policy-making.

The environmental justice movement seeks to address these flawed environmental policies and pursue equitable and sustainable solutions. By phasing out fossil fuel production and use, there is an opportunity to improve public health, tackle the climate crisis, and confront systemic racism simultaneously.
