International Rivers on NPR "Marketplace": Quake Puts Focus on China Dam Building

Aviva Imhof, International Rivers' Campaigns Director talks to Scott Tong of "Marketplace."
Marketplace says "Troops have been dispatched to shore up nearly 400 dams damaged by the Sichuan province earthquake. Mother Nature's mostly to blame, but there are worries over human error, too, since China has been exporting its dam-building expertise."
