Some electricity is made by damming rivers and using the water to push a turbine. What is a potential negative effect of this form of energy?

Question

Hydroelectric energy can cause the river to be heavily polluted.
Hydroelectric energy can destroy the habitat of wildlife that live in the river.
Hydroelectric energy can produce toxic waste that must be disposed of.
Hydroelectric energy can consume too much water.

Answer 1

A potential negative effect of hydroelectric energy is that hydroelectric energy can destroy the habitat of wildlife that live in the river. Damming rivers can significantly alter the local ecosystem, affecting fish populations and other wildlife that depend on the river's natural flow and conditions.
