He who says there's no such thing as global warming.
A friend of mine today firmly told me that there's no global warming and we should all stop trying to struggle improve efficiency (and then as an afterthought added "especially with policies, and liberalness and the such). It was a dumb inconsiderate reply but non the less, I snapped at him. I told him that we should just let ourselves cut down all the trees and pollute our atmosphere so much that marathon running would become a dangerous sport. He looked at me sheepishly and said something to the effect of well you shoulden't worry so much and Al Gore is a nutcase. Typical conservative catholic response. The point of telling you this story was to encourage you to say what you think in the comments section, and to inspire you to create ways to make us (the race of polluters) better.
So go on, debate it up!
