"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 discusses progress on wind, solar and geothermal energy on E&E TV's On Point. As shifting weather patterns and weather-related disasters become more prevalent, food insecurity is a growing concern. Brown explains why he believes food security is "the weak link" for our civilization.
