Gus Speth, author of The Bridge at the Edge of the World: Capitalism, the Environment, and Crossing from Crisis to Sustainability, has been praised by a wide range of readers.

A Christian writer from Read the Spirit called Speth’s ideas “a sign of hope.” A philosopher of social science at ChangingSociety lauded Speth’s “very powerful analysis,” while comparing his ideas to those of the Dalai Lama. The writer at Kale for Sale wrote that Speth “is bursting at the seams with information and urgency.” And Andrew Revkin on his DotEarth New York Times blog mentioned that The Bridge at the Edge of the World is on his reading table. And a review from the Yale Daily News noted that Speth’s book makes “an argument supported from professionals from several different disciplines.”

To hear what Speth himself has to say about his ideas, here’s a video of Speth’s April 22 appearance on OnPoint.

“During today’s OnPoint, Speth, a former chair of the Council on Environmental Quality and founder of both the Natural Resources Defense Council and the World Resources Institute, explains why he is unhappy with the current state of environmentalism. He also gauges the changing level of interest in environmental issues on college campuses throughout the country.”
