Question

Mention any one ecological problem caused by buliding large dams

Answer 1

negative Impact of DamsIn flat basins large dams cause flooding of large tracts of land, destroying local animals and habitats.People have to be displaced causing change in life style and customs, even causing emotional scarring. About 40 to 80 million people have been displaced physically by dams worldwide.Large amounts of plant life are submerged and decay anaerobically (in the absence of oxygen) generating greenhouse gases like methane. It is estimated that a hydroelectric power plant produces 3.5 times the amount of greenhouse gases as a thermal power plant burning fossil fuels.
