Fossil fuels are rock-like, liquid, or gaseous resources that are burned to generate power. They include coal, natural gas, and oil, and are used as energy sources in the electricity and transportation sectors. Fossil fuels produce hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury, all of which are harmful to human health. Air pollution from fossil fuels can cause multiple health issues, including asthma, bronchitis, cancer, heart disease, and premature death. Globally, fossil fuel pollution is responsible for one in five deaths, with up to 10 million people dying prematurely from it every year.

Fossil fuels produce hazardous air pollutants, including sulfur dioxide, nitrogen oxides, and particulate matter
Nitrogen oxide emissions have been dominated by fossil fuel combustion since the Industrial Revolution. Fossil fuel-powered cars, trucks, and boats are the main contributors to nitrogen oxide emissions, which produce smog on hot days and lead to respiratory illnesses from sustained exposure.
Particulate matter is another hazardous pollutant produced by fossil fuels. Mining operations, in particular, generate toxic airborne particulate matter. Black and Hispanic Americans are exposed to 56% and 63% more particulate matter pollution, respectively, than they produce. Globally, fossil fuel pollution is responsible for one in five deaths.

Burning fossil fuels is linked to asthma, cancer, heart disease, and premature death
Burning fossil fuels releases hazardous air pollutants, including particulate matter, nitrogen oxides, carbon monoxide, and volatile organic compounds. These pollutants have been linked to asthma, cancer, heart disease, and premature death.
Nitrogen dioxide (NO2) is formed from burning fossil fuels and emissions from vehicles and power plants. It is a major component of smog, which is more common in densely populated cities with more cars and greater fossil fuel usage. Breathing in NO2 can cause asthma, irritate the airways, and worsen existing lung conditions. Similarly, sulfur dioxide (SO2) from burning fossil fuels can harm the lungs and lead to respiratory issues.
The combustion of fossil fuels produces ultra-fine particles and aromatic hydrocarbons, which have been linked to cancer. A recent cancer risk analysis found that the oil and gas sector will put 14 million people in the US at increased risk of cancer due to hazardous air pollutants. This is a significant increase of approximately 55% compared to previous findings.
Particulate matter from fossil fuel combustion has also been linked to cardiovascular mortality and morbidity. A study found significant increases in cardiovascular hospitalizations on days with exposure to wildfire smoke, which releases particulate and gaseous air pollutants. Additionally, extreme heat caused by climate change increases the risk of cardiovascular-related mortality, especially for those with underlying cardiovascular disease or risk factors such as the elderly and communities of color.
The health impacts of fossil fuel pollution are significant, with research attributing about one in five deaths worldwide to air pollution from burning fossil fuels. In the United States alone, 350,000 premature deaths in 2018 were linked to fossil fuel-related pollution. Transitioning from fossil fuels to renewable energy sources can help prevent these premature deaths and mitigate the adverse health effects of fossil fuel combustion.

Fossil fuels contribute to climate change, causing extreme weather and rising sea levels
Fossil fuels, including coal, oil, and gas, are the largest contributor to climate change. When burned, fossil fuels emit greenhouse gases, such as carbon dioxide, that trap heat in the Earth's atmosphere. This leads to global warming and subsequent climate change. As the ocean warms, its volume increases, and melting ice sheets further contribute to rising sea levels.
Sea levels have risen roughly eight to nine inches in the last century, causing more frequent flooding, destructive storm surges, and saltwater intrusion. The high winds from hurricanes push a wall of water, known as a "storm surge," toward the shore. The rise in sea level propels these waves further inland, increasing the damage and deadly consequences of these storms.
The warming of the oceans also strengthens tropical cyclones, resulting in more intense and frequent hurricanes. Climate change, driven by the burning of fossil fuels, is linked to an increase in the frequency and severity of extreme weather events, including wildfires, wind storms, flooding, and droughts. These events lead to disasters with significant economic impacts, costing billions of dollars.
The continued burning of fossil fuels contributes to rising sea levels, which pose a significant threat to coastal communities and low-lying islands. Certain islands and coastal cities could be submerged underwater, and vital farmland in countries like Bangladesh, Vietnam, and Egypt is at risk of flooding. Additionally, rising sea levels can make freshwater sources too salty to drink.

Oil spills and fracking fluids cause water pollution, contaminating drinking water
Fossil fuels have been a major source of energy for decades, with oil being used to heat homes, generate electricity, and power large sectors of the economy. However, the use of fossil fuels has also led to significant environmental and health concerns, including water pollution from oil spills and fracking fluids.
Oil Spills
Oil spills, or the leakage of petroleum onto the surface of large bodies of water, have been a major environmental problem since the 1960s due to intensified petroleum exploration and the use of supertankers for transportation. While stringent regulations have reduced the number of major oil spills, thousands of minor spills and several major ones still occur each year, releasing over one million metric tons of oil into the world's oceans annually. Oil spills can harm marine life, damage plant life, and affect industries such as tourism and commerce. They also reduce the level of dissolved oxygen in the water and ruin the insulating and waterproofing properties of feathers and fur, leading to hypothermia in affected animals.
Fracking Fluids
Fracking, or hydraulic fracturing, is a process where water and chemicals are pumped at high pressure into wells to extract oil and natural gas. The resulting wastewater can be toxic, containing substances like arsenic, lead, chlorine, and mercury. There have been concerns about the potential contamination of groundwater and drinking water sources by these chemicals, particularly in areas close to fracking sites. In Pavillion, Wyoming, residents reported a bad taste and smell in their drinking water, and preliminary testing suggested the presence of toxic chemicals typically found in fracking wastes. However, some studies and governmental organizations have found no evidence of fracking chemicals in drinking water, citing the distance between groundwater and fracking sites as a mitigating factor.
In conclusion, while fossil fuels have been essential to our energy needs, the environmental and health impacts of oil spills and fracking fluid contamination cannot be ignored. It is crucial to balance energy needs with the potential risks to human health and the environment posed by the use of fossil fuels.

Fossil fuels are the primary driver of plastic pollution, contaminating human bodies and the environment
The pervasive use of plastic has led to widespread plastic pollution, contaminating the air, water, soil, food systems, wildlife, and human bodies. Improperly discarded plastic waste harms the environment, driving biodiversity loss, and ecosystem degradation. It threatens human health, impacts food and water safety, and contributes to climate change. Plastic pollution affects all land, freshwater, and marine ecosystems, with over 1500 species in these environments ingesting plastic, leading to internal injuries and death.
Microplastics, resulting from the breakdown of plastic, have been detected in human blood, livers, kidneys, placentas, and the gut microbiome. They can enter the human body through contaminated food and drinks, including tap water, beer, and salt. The presence of microplastics in the human body may be associated with adverse health effects, including potential impacts on fertility and reproductive health. Carcinogenic chemicals in plastics can also leach into water supplies, potentially causing developmental, reproductive, neurological, and immune disorders.
Addressing plastic pollution is crucial not only for environmental protection but also for safeguarding human health from the associated risks and pollutants. Efforts to reduce primary plastic production, promote sustainable alternatives, and improve waste management practices are essential to mitigate the harmful impacts of plastic pollution on both ecosystems and human well-being.
