Question

Now it is established that big dams are causing loss of biodiversity. Give reason

Answer 1

HERE IS YOUR ANSWER

There are about a hundred of oppositions for construction of dams and multipurpose projects.

This is because, when dams are built, it leads to huge deforestation leading to disastrous consequences.
Then the wildlife of the place is affected and animals native to the local area should migrate or die.
A large amount of vegetation under the stores water leads to slow decay and release of greenhouse gases like methane.
