"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 writes for Guardian.co.uk in "This will be the Arab world's next battle," regarding how population growth and water supply are on a collision course and how hunger is set to become the main issue. Posted April 22, 2011.
