Environmental optimism: an example

Glen Hiemstra commented on my blog yesterday, and he also blogged about Al Gore's speech calling for a 10-year program to end the use of carbon-based energy sources for generating electricity.

Al Gore has presented a great example of environmental optimism on a grand scale, and he's done it in a manner I found challenging and uplifting, not depressing and defeatist. You've probably read about it by now, but I encourage you to watch the video.
