In what ways do dam construction alter the ecological balance? Elaborate with appropriate examples.
Dam construction has long been seen as a key solution to various issues, including water management, hydroelectric power generation, and irrigation support.

Following Mahatma Gandhi's philosophy of non-violent movements, which emphasized peaceful protest against unjust practices, various movements have arisen worldwide, focusing on environmental sustainability and the preservation of ecosystems against dam constructions. This essay examines the ecological impacts of dam construction and explores instances where non-violent movements have successfully challenged these projects.
