It's about Evangelism

Nope, I am not referring to Guy Kawasaki this time ! Back in early 2006, former Vice-President and ex-future President Al Gore was the special guest at Dave Letterman 's Late Show. That was for the release of An Inconvenient Truth in America. Almost a year later, one can see how Gore keeps standing firm on the key message : it's up to us to save our children' s Planet Earth. That is Evangelism per se.
