Question

explain any three reasons for which the multipurpose projects and large dams have come under great security and opposition in the recent years

Answer 1

Hey mate !

large dams have come under great scrutiny and oppositions for various reasons.

*regulating and damming of rivers affect natural flow causing excessive sedimentation at the bottom of the reservoir, resulting in rockier stream beds and poorer habitats for aquatic life.

* dams fragment rivers. Making it difficult for aquatic fauna to migrate. Especially for spawning.

* it also submerge the existing vegetation and soil leading to its decomposition over long period of time.

have a nice day ✌
