Yet more evidence that the Agricultural Revolution was humanity's greatest blunder.

Al Gore realizes that cigarette smoking is a significant contributor to global warming. Udolpho comments:

Of course it is. Cigarettes: deadly to smokers, even more deadly to non-smokers, and most deadly of all to the planet itself. Please wait, I am going to go out and buy a carton of Pall Mall. (I guess that Indian with a tear rolling down his craggy cheek is the real villain.)

Good luck getting the world to ban cigarettes Mr Gore! Countries like China and Iran are probably more likely to give up enriching uranium than giving up tobacco.

Just because you're a non-smoker doesn't mean that you aren't an environmental threat. Human respiration is based on the production and emission of carbon dioxide into the atmosphere, thus potenially affecting the global climate. We're all sinners in the Church of Gore-ianity.
