dams do impact on the environment. They usually flood large river valleys, covering a lot of native habitat with water, displacing animals and sometimes people. In China more than one million people were moved when they built the "Three Gorges" dam. Many archaeological sites are now unreachable under water and there is environmental damage along the banks of the many tributaries of the Yangtze River.
