dam

The Narmada Bachao Andolan (NBA), the local movement opposed to the damming, has rallied international attention against the project, which includes plans to construct 3,200 dams on the river.

Damming and diverting rivers damage the trust by preventing the natural flow of sand to the beaches.

Completed in 1963, at the height of a period when America was damming everything that flowed, the dam destroyed beautiful, red-rock Glen Canyon and altered the ecology of the Grand Canyon area permanently.

The founder of China's Green Earth Volunteers, Wang spearheaded the fight--successful, so far--against damming the Nu.

But perhaps the greatest problem of restoring ecosystems is that, once modern society has dramatically altered an ecosystem--for instance, by damming a river to provide hydropower--it can be difficult to restore that ecosystem successfully, partly because so many people rely economically on its altered state.
