For me it is not a simple "yes or no" question. I recognize that the global climate changes and is changing now, I consider it to more of a cyclical change rather than man made. That's not to say that our existence on the planet does not contribute, it would be foolish to think otherwise, I just question exactly how much our presence actually effects the climate changes. All that being said, I see no reason why people shouldn't do what they can to minimize their negative impact on the environment. I don't see any reason to go all green extreme jihad, exercise some common sense.
That being said, I voted "He's a goofball."
