When products be manufactured many an(prenominal) chemicals argon used to create it. However because of the difficulty and cost of properly disposing of these products they are often emitted into the atmosphere with little or no treatment. Th e term was first base considered to be important about 20 years ago when scientists in Sweden and Norway first believed that acidic rain may be causing large(p) ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a occlusive of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers/lakes care the river Tovdal in Norway had not yet begun to die. However by 1926 local inspectors were noticing that many of the lakes were beginning to show signs of death. Fish were found dead along the banks of many rivers. As the winters ice began to melt off more(prenominal) and more hundreds upon hundreds more dead fish (trout in particular) were being found. It was at this time that scientist began to seem for the reason. As the scientists continued to work they found many piles of dead fish, up to 5000 in one pile, further up the river. Divers were move in to examine the bottom of the rivers. What they found were many more dead fish. Many live and dead specimens were taken back to labs across Norway.
