Acid Rain :: essays research papers fc

There is a grand problem today in our world, and its effects are astronomical. This problem is red-hot rain. Acid rain is any precipitation rain, snow, or fog that contains stingings such as sulphur dioxide and nitrogen oxide. These chemicals are byproducts of industrial processes and or intense of fossil fuels. The United States pumped a disgusting 16.8 tons of SO2 into the atmosphere in 1995 (Alm 349.) Nitrogen oxide emissions come mainly from the combustion engines, that operate our vehicles, furnaces, industrial and electrical utility boilers and engines. It is hard to believe that in the United States, to a fault in 1995, the NOx emissions were an estimated 21.7 tons in weight ( Alm 349.) If these pollutants are fork up in the atmosphere, they can travel, via wind currents, long distances, and return to the earth fade away in one or more types of precipitation contaminated by said chemical waste. Regular old rain, not contaminated by acid, is slightly acidic, with a p H of 5.6. This slight acidity is caused by century dioxide, that is naturally found in the atmosphere.Acid rain effects both single aspect of every ecosystem. Acid rain is devastating to aquatic life, crops and forests, and not to mention human life. One would tend to think that acid rain would greatly affect trees and plants, this based on the trees direct contact with the acid rain. An estimated sixty five percent of trees are effected by acid rain. The leaves of the trees are scarred by the rain, the seeds sterilized, and the immune system of entire forests are damaged, exposing them to disease infestation. The growth of forestlands can in addition be greatly slowed by the effects of acid rain. Lakes are also greatly affected by contaminated precipitation. It has been discovered that some xx thousand lakes have been turned acidic through groundwater contamination by acid rain. Fish start to die at around a pH of below 5.6. There are natural buffers such as calcium and lime i n lakes to help neutralize these acids. If there arent enough buffer materials, or they are completely neutralized by the acids, the pH will not get better, and the lake will become sterile (Public 22.) What can we do to help control the problem of acid rain? Well, the obvious comes to mind. The emissions of sulfur dioxide and nitrogen oxides that are released into the air must be controlled.
