"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 gives the inaugural address for the University of Maryland's Environmental Lecture series. The topic is his new book Full Planet, Empty Plates: The New Geopolitics of Food Scarcity.
