The Bridge at the Edge of the World: Capitalism, the Environment, and Crossing from Crisis to Sustainability (Yale U. Press), by James Gustave Speth, dean of Yale University's School of Forestry and Environmental Studies, cofounder of both the Natural Resources Defense Council and the World Resources Institute, top  environmental  adviser to President Jimmy Carter, and head of the UN Development Programme during the 1990s.  Socialism is not the answer and neither is capitalism as we know it. Main stream environmentalism has been getting stronger, but the global economy is growing faster and devastating the environment. There's a need to step back, outside the system, develop a more powerful critique, and take on the big issues--over consumption, inaccurately low prices for most market products, revising the basic charter of the modern corporation to serve the long term interests of all the stakeholders, from workers and communities to future generations and the environment, etc.--if we're going to get beyond the capitalism of the day to a third alternative.  http://www.emagazine.com/view/?4429 Summary of interview by Melinda Tuhus in EMagazine.
