Question

List three problems which arise due to construction of bid dams. Suggest a solution for these problems.

marine animals die due to water logging for long time
when water is set free the place where it was earlier developes into a swamp

Answer 2

construction of big dams need a lot of space due to which many people living in that area have to shift and leave their homes
- big dams do not give much returns in future as compared to high cost
- their construction cost is very high
solution of this:
we should construct small dams as their cost of construction is less and they require less space
