That is why the Canadian political science started the ELA. The ELA (Experimental Lakes Area) is a case station that allows scientists to observe lakes and study their pollutants and watersheds. They sample on these lakes in the hope of finding a consequence to re-purify them and lakes all everywhere the world. However, the ELA has become a very disputed subject, as umteen believe that investigateing with the lakes is doing more harm than good. This piazza paper ordain look at the pros and cons of ELA, and then take aim a decision on which choice is better. The lakes apply in this experiment are located in southern Canada, specifically northwest Ontario. 58 small lakes in this area are creation examined year round. The lakes are used for different experiments. one lake was used to test the affects of window paneic rain on lakes. cutting was step by step added to the lakes everyplace a period of time. After 5 old age of this, the pH levels had dropped from 6.7 to 5.0 (Effects of Acid Rain on Lakes).

drastic changes began had happened in the lakes, such as the disappearance of minnows, cray tilt, and shrimp, and many of the fish, such as trout, had begun to starve and stopped reproducing. Noticing this, the scientists decreased the amount of acid over the years, and the ecosystem of the lake began to improve. Many of the species in the! lake looked healthier, and more plentiful. By doing this they turn out that acid rain has a huge impact on the underwater food chain (Effects of Acid Rain on Lakes) as the acid kills of the smaller fish that the big ones eat, and messes up the chain. They also tested birth control drugs with fish, and discovered that they interfered with fish reproduction (male fish were being turned into females), and...If you want to score a full essay, order it on our website: OrderCustomPaper.com
