Acid Rain


Acid rain is rain that is more acidic than usual. Acid rain is formed when nitrogen oxides and sulfur oxides, which are formed from burning coal, combine with water in the air. This forms nitric acid and sulfuric acid. Acid rain is a problem because it can make lakes and ponds so acidic that plants, amphibians, fish, and insects can no longer live there. Acid rain can also be strong enough to damage the surface of buildings and statues. In the U.S., the government has passed a number of laws to reduce air pollution. The amounts of major air pollutants have decreased and newer cars and power plants are less polluting than old ones. Also, individual people can take voluntary measures like using public transport instead of driving.Acid rain is a big problem, but maybe in the future, near or far, the problem will improve.
