“If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence.” — Bertrand Russell, Roads to Freedom
I found this quote on a friend of mines website: Global_Issues

824: “Earth provides enough to satisfy every man’s need, but not every man’s greed” – Mahatma Gandhi
Explains perfectly the global warming issue…
