Answer:
Multipurpose projects and large dams have come under scrutiny and opposition because of the following reasons:
Large dams affect the natural flow of rivers. This results in hampering the flow of sediments. Excessive accumulation of sediments in the reservoirs causes damage to the marine life.
The dams on the flood plains submerge the vegetation and soil leading to its gradual decomposition.
It further results in floods due to the deposition of sediments in the reservoirs.
It causes destruction of the forest areas and the displacement of tribal and local communities.
The construction of big dams destroys the natural surroundings and biodiversity of an area.
If large dams are constructed at the place where tectonic plates meet, it can induce earthquakes.
