1.	Give scientific reasons - Large dams destroy ecosystems.
Answer» Says the short answer is “yes” dams do destroy rivers as ecosystems. “Many of the dams built during the 20th century have proven to be river KILLERS. Examples are numerous and notorious.” HOWEVER he also notes the positive impact dams have had in reducing the sum of human misery and encouraging development. “For example, the drought in the Horn of Africa was a disaster that cost the lives of millions, but the High Assam Dam spared Egypt from a drought that WOULD have been truly catastrophic,” says Thorne. Many of the dams built in the last century were poorly designed and many are now in the process of being REMOVED. He says the EVIDENCE so far is that nature bounces back surprisingly well after dam removal hope this helps you
