"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 speaks as a keynote at the 2012 Limits to Growth Symposium hosted at the Smithsonian. Posted March 28, 2012.
