It's a pessimistic approach because look how long it takes people to discuss this, while the problem gets worse, it's like having a meeting of what to do when a tidal wave comes, while there is one offshore showing up.
People are too concerned now with making money then with change, and all the people that want to make a change feel they can't, IE everyone still driving, if we all cared alittle more we would stop driving and adapte our lifestyles, but we are too comfortable.
Yes I agree the CFC thing did a big change and people made a giant about face on it, but if you look at the whole Global warming issue, there are signs but people are disproving them, which inturn means people have doubts. You cound't disprove a giant hole in the ozone, it was there, it was real.
3rd worlds are doing what they can to survive because no one is helping them or educating them.
We need to face the facts that if we wanted to change we could but the social upheaval would be catastrophic. So instead a gradual approach should be taken, but who puts the plan into action, or even comes up with a plan, world leaders if they gave a **** about what they walk on instead of who they walked on would be getting things done. Hopefully soon we can see some real change. And on a note of capitalism, look at what GM and the other 2 have been doing for years, LOW MPG cars and railroading bills Cali has tried to pass in the senate.
