The following YouTube clip is Part 4 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 need to cut global carbon emissions by 80% by 2020, creating huge new industries and new jobs. Just by changing our light bulbs we could close 750 coal fired plants worldwide.
He says we can cut emissions this far for less effort than the mobilisation required for WWII!
