This going on and on about how terrible a carbon-based economy is, these people are full of crap. They don't know what they're talking about. Their motives are not necessarily good just because they say they are being good. It's peace, love, and understanding. To which I can just say, "Shut up." Human liberty, rule of law, and free markets fix this stuff. It isn't necessary to go around being the Mia Farrow of the ecosphere.
