Penn: Is passion supposed to replace common sense? We understand the desire to join up and do something important. It's sexy to save the world. But, you gotta spend a couple of minutes to find out if you're really saving the world and not just being herded around by some politically motivated a**holes who may not really care that much about the environment but see this as some chance to raise money for whatever they think is a good idea. No end justifies the means of lying.
