I don't care about whether or not Gore drives a hybrid of subscribes to green energy. All of that has little effect on the environment and doesn;t really paint Gore as a hippocrit.
The zinc mine? Um, thats a bit damning... also is the fact that global warming is STILL an unproven theory with many highly intelligent and independent detractors.
My biggest problem with Gore is how he has attempted to just squash debate by proclaiming that any scientists that disagree with him are either in the pocket of "Big Oil" (who he apprently owns a bit of) or are just wackos. This does nothing to further the debate and makes him look like an idiot when legitimate scholars and and researchers debunk his fact as theory.
I'm not saying that global warming doesn't exist or isn't happening, I don't know. I also don't know if our exitence on this planet even has that much of an effect on GW if it is happening. To just assume so is both arrogant and willfully ignorant. I do know that there is a lot of evidence to its contrary and even evience that the earth is beginning a COOLING period (I'll try and find the links later during my lunch break) that is just as worthy of examination.
In the end, my biggest problem si that Gore states theory as fact and then expects us to completely change out way of life according to his misleading statements.

They pretty much re-state what I summarized but with an insane amount of data and hard science.
