Health externalities of burning fossil fuels.
"Burning fossil fuels creates air pollutants such as particulate matter, carbon monoxide, sulfur dioxide, ozone, and mercury. These pollutants lead to health impacts including asthma, lung disease, bronchitis, and other chronic respiratory diseases that may lead to premature death. Air pollutants from fossil fuels also contribute to the development of lung and other cancers; lung cancer accounts for 30 percent of cancer-related deaths each year. Air pollutants, such as those released from vehicles and power plants that rely on the combustion of fossil fuels, cause 200,000 premature deaths each year.
Taking into account the coal power sector alone, it is estimated that fine particulate matter from U.S. coal plants resulted in 13,200 deaths, 9,700 hospitalizations, and 20,000 heart attacks in 2010. Coal-fired power plants are also the largest source of airborne mercury emissions in the United States. Mercury can move through the food chain and accumulate in the flesh of fish, posing the greatest risk to pregnant women."
