American cynic Ambrose Bierce once described a Christian as "one who follows the teachings of Christ in so far as they are not inconsistent with a life of sin."
I think that description also fits for most people who say they are concerned about the environment --- they believe in environmentalism so long as it's not inconsistent with their lifestyles of fun.
That's why all the pro-Kyoto Accord scientists and politicians and media-types like to downplay the cold hard reality of fighting "climate change": the only way to truly reduce greenhouse gas emissions is to drastically reduce our standard of living.
And nobody really wants that to happen.
Just like developing countries such as China and India won't want to put their plans to improve their standard of living on hold for about 40 years too.
As a story put out by the Reason Foundation puts it, you can't fight poverty and carbon reduction at the same time.
