Hydroelectric dams significantly alter the environment by disrupting water flow patterns, fragmenting habitats, hindering fish migration, changing water temperatures, causing deoxygenation, and emitting greenhouse gases. These impacts affect aquatic ecosystems, including fish populations, downstream habitats, and overall water quality. The dam’s alteration of natural processes can have long-lasting consequences for the environment, contributing to the…
