Saving Civilization Is Not A Spectator Sport

We're making strides toward environmental sustainability, but is it enough? And what, if anything, can we do to help?

Lester Brown, President, Earth Policy Institute

Brown sees concern in the merging of world food and energy economies. Putting corn ethanol in gas tanks and grain-intensive food (beef) into more human bellies will drive up commodity prices and exacerbate fresh water scarcity. Though he believes the Earth is under stress, Brown is hopeful, in part because for the first time since the Industrial Revolution we have begun investing in energy sources that can last forever. Brown also will comment on how the melting glaciers of Tibet could affect the price of a bagel in California.
