IMO Al Gore just made it up because he couldn't get famous by being president, because he lost to George Bush.
I'm not sure how people can call out a system that can be proven by science (as far as I know), however I do agree with the "green" bullstuff. We need to simply be more responsible, not buy into these stupid fads.
Anyway, did not sign. You really think they're going to listen? They're being destroyed economically, and these petitions don't help, and do more damage if they work. JEEP is going to die, stop being so pissy about it.
