Question

Big dams have their own problems. Discuss.

Answer 1

Big dams have large water reservoirs to store a huge amount of water at a time. If the rainfall is heavy and the water exceeds the storage limit of the reservoir, then water is released from the dam. This causes heavy flooding, which destroys wildlife, agriculture and displaces people from their homes. Also, large amount of water stored in dams can cause earthquakes in regions prone to tectonic activity.
