Air Pollution. Cars and trucks are the number one hazardous air polluter, according to the EPA. Cancer-causing and asthma-inducing pollutants include Volatile Organic Compounds, Nitrogen Oxides and Particulates, and CO2, the major greenhouse gas. Air pollution rains out as water pollution. Increasing vehicle miles travelled increases pollution.
