Ross Gelbspan needs to be beaten. He's another Chicken Little who refuses to accept the possiblity that climate change isn't caused by humanity. The Earth has been here for billions of years, it'll be here for billions more. There was life before us, and there will be life afterwards. Whether or not it will be human life is what's at issue. Anyone who thinks we can control nature should take a look at New Orleans.
Before you jump all over me, I've said it before, that doesn't mean we shouldn't try to reduce pollution everywhere in the world. What it does mean is that the Earth is NOT fragile. We are.
Have faith, though. We're everywhere. We're equipped to live in virtually any environment. The human race won't be going extinct anytime soon. We may have to move back from the coasts for awhile, though.
