Acid Rain
Acid Rain
Acid rain is a very big issue in environmental science today because it is not only a form of air pollution, but it is also a form of water and soil pollution as well. Acid rain forms when emissions from power plants release dry acids into the air, mixing with other chemicals present in the atmosphere. Because acid rain is corrosive, it creates widespread problems in many environments all around the world. The problem begins with the production of sulfur dioxide and nitrogen oxides from the burning of fossil fuels, such as coal, natural gas, and oil, and from certain kinds of manufacturing. Sulfur dioxide and nitrogen oxides react with water and other chemicals in the air to form sulfuric acid, nitric acid, and other pollutants. These acid pollutants reach high into the atmosphere, travel with the wind for hundreds of miles, and eventually return to the ground by way of rain, snow, or fog, and as invisible dry forms.
Damage from acid rain has been widespread in eastern North America and throughout Europe, and in Japan, China, and Southeast Asia. Acid rain leaches nutrients from soils, slows the growth of trees, and makes lakes uninhabitable
