The following YouTube clip is Part 3 from a recent lecture Lester Brown gave on Plan B 3.0: Mobilizing to Save Civilization and will take you into the heart of the Plan B message. The presentation was to the Chemical Society of Washington on May 8, 2008.
Lester, who is President of the Earth Policy Institute, talks about the growing list of failing states and that this represents an early sign of a global economic decline. The main drivers are peak oil, climate change and rising food prices. Now that we can convert grain into fuel, the price of grain is tied inextricably to the price of oil.
