Why dams are criticized?

Answer 1

Dams are often criticized for their environmental impact, as they can disrupt local ecosystems, alter water flow, and displace wildlife. Additionally, they may lead to the displacement of communities and loss of agricultural land, affecting livelihoods. Concerns about sediment buildup and water quality issues also arise, along with the potential for catastrophic failures that can endanger lives. Critics argue that the long-term social and ecological costs often outweigh the short-term benefits of dam construction.
