Acid Rain :: science

Acid RainINTRODUCTION Acid rain is a great task in our world. It causes fish and plants to die in our waters. As well it causes harm to our own race as well, because we eat these fish, drink this water and eat these plants. It is a problem that we must all face together and try to get rid of. However acid rain on its own is not the biggest problem. It cause numerous other problems such as atomic number 13 poisoning. Acid Rain is deadly. WHAT IS ACID RAIN? Acid rain is all the rain, snow, mist etc that falls from the sky onto our planet that contains an unnatural acidic. It is not to be muzzy with uncontaminated rain that falls, for that rain is naturally slightly acidic. It is caused by todays industry. When products are manufactured legion(predicate) chemicals are used to create it. However because of the difficulty and price of properly disposing of these products they are often emitted into the atmosphere with little or no treatment. The term was first considered to be impo rtant about 20 years past when scientists in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist anchor 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 period 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 like 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 meld off more and more hundreds upon hundreds more dead fish (trout in particular) were being found. It was at this time that scientist began to search for the reason. As the scientists continued to work they found many piles of d ead fish, up to 5000 in one pile, further up the river. Divers were sent 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.
