Tina Loo studies the impact of  hydropower projects on native people in Canada, and here she talks with the Old Mole's Laurie Mercier about how the techno-perspective of policy makers blinds them to the impacts of their projects on life in the areas where they are  located.    Professor Loo will be appearing next week (Nov. 6-7)  in Vancouver, WA at a major conference about dams -- Reversing the Flow: Big Dams, Power, and People in Global Perspective.
