Quizplus · Accepted Answer

Dams are primarily built to generate electricity, prevent flooding, and provide irrigation and drinking water. While some dams may improve the habitat for native fish, this is not the primary reason for building them. Draining wetlands for urban development and transforming watersheds into farms, towns, and recreational areas are not ecological benefits of dams, but rather potential negative consequences. Controlling the spread of waterborne diseases is not a benefit of dams, as they do not necessarily address the root causes of the diseases.
