"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 Peter Thomson of Public Radio International in the episode "Egyptian protests, climate change, and food prices." Posted February 8, 2011.
