Environment issues of the 2008 election.

I chose the above link because CNN is a reliable news source and it gives a very short to the point explanation of the 2 canidates and their positions and ideas about the environment for the coming election. And it also has a "sound off" section that allows readers to state their opinions, which is a benefit.
