I honestly do not believe that global warming is mainly caused by humans. In the 1970s there was a huge amount of people who believed that the world was actually going into the ice age. There were all sorts of magazine covers on the subject. Even TIME magazine had one.
http://www.time.com/...,944914,00.htmlRead the article. You'll notice that they're saying almost the exact same things that they are saying about global warming now. And here's the kicker. On the second page of that article they also blamed man!

Man, too, may be somewhat responsible for the cooling trend. The University of Wisconsin's Reid A. Bryson and other climatologists suggest that dust and other particles released into the atmosphere as a result of farming and fuel burning may be blocking more and more sunlight from reaching and heating the surface of the earth.
Now to say that just because back then is a lie global warming must be a lie too would be stupid, but it is certainly something to consider. The global cooling theory of the mid 70s was just as hyped up as the global warming theory is now. And guess what? Even though they had DECADES of data which was supposedly showing that the climate was cooling the ice age never came. Our planet is also not heating up nearly as quickly as they had predicted two decades ago before the theory really caught on.
My point more is that the earth warms up. The earth cools down. Sometimes it gets real hot and sometimes it gets real cold. It's just how it is. Geologists can tell you that this has been happening since the dawn of the earth. Maybe we're causing it maybe we're not. I highly doubt we're the main cause. Maybe we're not helping but the amount of CO2 we're putting in the atmosphere is a drop in the bucket from the amount that gets poured in from natural sources. So if this theory remains true we are just not helping but at least in my opinion we are absolutely positively not the cause. If anything cows are doing us in more than anything else

Eat emu and kangaroo burgers perhaps.
I, however, completely support the going green movement

Why? Because I want cleaner air. If you live anywhere in Detroit... even places like Winsor, Canada living there is like smoking two packs a day. It's absolutely disgusting the amount of chemicals we're pouring into the air sometimes. I'd also love to see us stop being such a wasteful society. So I don't give a damn if we're getting hotter or not. I like the way we're changing
