cause air pollution. The major air pollutants are acid rain‚ smog‚ fly ash‚ and indoor air pollutants. Acid rain is caused by when exhaust from burning fossil fuels combine with water vapor in the atmosphere and falls as rain or snow. Acid rain causes extensive damage to water‚ forest‚ soil‚ resources‚ and even human health. Many lakes and streams have been contaminated by acid rain and this had lead to a diminished population of fish. Acid rain has lead to the international limitations of sulphur
