"Attention has focused on oil insecurity, and rightly so, but it is not the same as food insecurity. An empty gas tank is one thing, an empty stomach another. And while there are substitutes for oil, there are none for food." –Lester R. Brown, Plan B 4.0: Mobilizing to Save Civilization.
Lester Brown is interviewed by Christal Smith for the Huffington Post in "The Weather Becomes the News: An Interview With Earth Policy Institute Founder Lester Brown." Posted July 21, 2011.
