I think that both sides have their pro's and con's
Healthy discussion is part of good science provided people don't get too emotional about it. Unfortunately sensibility goes right out the window sometimes. The planet seems to take care of it's self. 650 Mya the world was frozen from pole to the equator. In the middle Jurrasic there was no ice at all. The planet manages this without any intervention by us. A big problem is that we see ourselves as something separate from the planet. We are part of the planet and our actions are part of the planet. If we destroy ourselves, life will raise up another creature to take our place. Our loss and the planets gain! The evolution of an oxygen atmosphere 2.6 Bya was also catastrophic development at the time for the cells living then. But because of it we are here today. I think that it's obvious that all the chemicals (not just CO2) released into the atmosphere changes our environment. But as history shows the people as a whole always need to fear some catastrophic end. A few decades ago it was nuclear annihilation. Now the cold war is over it's green house warming. When we solve that one another global fear will take it's place. Let's not forget that a bit of green house warming is a good thing. (possibly better than another ice age which is the way it was going before the industrial revolution). Human avarice and greed are the currency of the day, perhaps it always has been. Only seeing the now rather than the future. While we live by the mighty maxim of economy first, we are unlikely to change that. And living for the ME rather than the US. How about some corporate responsibility. Something not often covered by modern economics! Let's celebrate the opportunity for healthy discussion. Even if not everyone agrees. That's part of good science. Wasn't the last world war fought for those principles. Lastly I'd like to point out Easter Island. Every thing was great at the start, then over population, chaos and collapse. Our world is like Easter Island. The planet can only support so many people without destroying our environment completely. My solution would be free televisions for everyone. Together with foxtel style programming, our population problems would be solved! Cos everyone would fall asleep watching and less hanky panky would mean less babies. Simple but effective.
To summarise:
We see ourselves at the centre of the universe.
History has proven that this is wrong.
The Life on the planet will go on with or without us.
It's our choice if we are going to be there or not.
