Below, you can watch Al Gore talk about tangible ways that you can be a good environmental citizen. The first 5 minutes start with some wit and banter that would have served him well in 2000; the next 10 minutes get down to some business.
A few, quick related items: Google offers a free online copy of Gore's major book on the environment, Earth in the Balance. Published first in 1992, the book demonstrates, among other things, Gore's sustained commitment to this issue. Next, if you've never seen An Inconvenient Truth, then you may want to give a listen to Gore's speech at Stanford's Graduate School of Business (listen on iTunes here). It covers much of the same ground. Finally, this all reminds me of a television exposé that Bill Moyers aired a few months back. It's called "Is God Green?," and it takes a lengthy look at how conservative evangelical movements in the US are increasingly taking global warming seriously as an issue. (You can watch it here.) And if you know America, you know that's essential for changing the nation's environmental policies.
