Question

write a short note on the environmental aspects which are required for building huge dams​

Answer 1

Answer:

Dams can create a reservoir to hold water, protect areas from floods, or generate clean electricity. dam also physically blocks migrating fish and changes the overall biology of the life in the river by changing the natural water flow.

Dams disrupt the ecosystems within and around rivers, reduce biodiversity and mess with water quality.

Solutions to make them more sustainable include using fish-friendly turbines or lowering their height. In some places, turbines are even put directly into rivers, streams and the ocean.
