Over 125 million people in America live in places with way too much air pollution. The EPA blames the early deaths of over 64,000 people in America on air pollution every year. Asthma, lung and heart disease are also made worse by air pollution. adding on to the negative impacts on health and the environment, air pollution in the form of smog and acid rain have been shown to kill agricultural crops and harm buildings at a cost of between $2 and $3 billion per year.Cars and other vehicles are the biggest source of city air pollution, creating more than two-thirds of the carbon monoxide in the atmosphere, a third of the nitrogen oxides , and a quarter of the hydrocarbons in short the tings that cause smog. Some emissions put out by cars and trucks are known to cause cancer, including toxic things like soot, arsenic, formaldehyde, and lead. "In the 1996 National Toxics Inventory, EPA estimates that mobile sources such as cars, trucks, and buses release about 3 billion pounds of cancer-causing, hazardous air pollutants each year". http://www.epa.gov/
