Notes
  • The Stanford University student government asked me to develop a presentation for high school students for Earth Day. That evolved into: 'GLOBAL WARMING IN CALIFORNIA, WHAT HIGH SCHOOL STUDENTS CAN DO. I reused much of the material at Trinity church for the 'Why Being Green Is Not Enough' presentation. The handouts for both presentations are also posted on SlideShare. Also see www.EltonSherwin.com
