I talk with Lester Brown, environmentalist and founder of the Worldwatch Institute, and founder and president of the Earth Policy Institute about his Plan B, kicking the fossil fuel habit and technologies being put in place right now to make the world more energy efficient.

The PBS premiere of Journey to Planet Earth, based on the book, Plan B: Mobilizing to Save Civilization by Lester Brown, has aired. Look for repeat showings on your local PBS stations. Buy the book.
