The Effects of Acid Deposition on Humans and the Environment :: Environmental Ecology Essays Pollution Acid Rain

window glass DepositionOne of the biggest environmental problems that needs traffic with in society today is unpleasant deposition. It is largely caused by servicemans, and causes a great deal pollution to the environment and harms people and buildings as well. Although there ar marginal positive sides to this issue, the negatives far outweigh it and call people around the macrocosm to take action to reduce and even solve this problem. Coming in twain wet and dry forms, acid deposition consists of acidic pollutants including newton oxides and sulfur oxides that have been deposited from the tune to the surface of the earth. There are both wet and dry forms of acid deposition, wet forms being referred to as acid precipitation. Acid precipitation is the result of sulfur and nitrogen oxides reacting in the strain with water vapor. This returns to the earth as acid rain or snow. wry deposition occurs when these oxides react without water and they settle out of the atmosphere onto the earth. Acid deposition can come from a number of different sources much(prenominal) as smokestacks, trucks and cars. More than 90% of the sulfur in the atmosphere comes from humans. burn burning, the smelting of metal sulfide ores, and automobile exhaust are major human contributions to sulfur dioxide in the atmosphere. Similarly, 95% of the increased nitrogen oxide levels in the atmosphere are a result of the activities of humans. The activity that contributes the most to these elevated levels is the blaze of oil, coal, and gas. Attention was first drawn to acid deposition in the seventeenth century when the bad effects of industry and acidic pollution on both vegetation and people were spy. In the 1960s, it became an international problem when fishermen noticed declines in fish numbers and diversity in lakes across northeasterly America and Europe. Acid deposition causes many problems such as these worldwide, and is all the way a problem that needs to be properly d ealt with.There are different negative affects of acid deposition to different environments on the earth. In soils where a possible buffer of basic material isnt as great, plant nutrients are often lost, the germination of seeds and the growth of young seedlings are hurt, and plants may become over-fertilized by nitrogen. The plants in this instance often fix reduction in growth rates, flowering ability, and overall yield. This makes the plants more penetrable to disease, insects, drought, and frost. Trees are also affected by acid deposition.
