Question

Describe any three disadvantages of large dams.

Answer 1

Three disadvantages of large dams are:

1. Environmental Impact: Large dams can significantly disturb river ecosystems, reduce biodiversity, and alter fish migration patterns.
2. Displacement of Communities: The construction of big dams frequently results in the migration of nearby residents since reservoirs flood significant amounts of land.
3. Sedimentation: Over time, huge dams can deposit silt and sediment, limiting their ability to store water and affecting the dam's durability.
