"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.
Ewaldy Estil, upon receiving a copy of Plan B, was so inspired by Lester's ideas to save civilization that he composed a song based around Plan B. Posted December 15, 2010.
