Will Richardson has posted this video called ‘How it all ends’ on his site. He found it at Chris Lehmann’s site. It’s a Science teacher’s attempt to explain the debate surrounding global warming and what we should be doing about it. Another example of the power of YouTube to enable us ordinary joes to gain a voice and be heard. The message here is clear – pass it on. Your science teachers could find this a valuable teaching tool when addressing Global Warming issues.
