Acid Rain

Acid rain usually has a pH level of .6 but with pollution, weather patterns or elevated topography acid rain can reach 4.2. In the Adirondack Mountains, in New York, the pH of the lake became so acidic that fish did not survive. As a result, the animals of area also dispersed. Acid rain is caused by NO2 and SO2 emissions from cars and factories. It can come in the form of rain, snow, fog, or dew. In the mountains, areas with heavy fog, are greatly affected by acid rain. Trees die from the high acidity and animals suffer as well. In Indiana, heavy pollution blows east and also adds to acid rain. However because Indiana has heavy limestone deposits we don't feel the full affects of it. The calcium carbonate in limestone acts as a buffer and neutralizes the pH of acid rain. If acid rain is every going to stop, pollution must also slow down.
