Check this “unintended consequence” out at Amy Ridenour’s National Center Blog:

I grant the benefit of the doubt here because 94% of the environmentalists who are causing rainforest destruction also probably support PETA in their killing of animals. It’s like the Wizard gave the Scarecrow the heart.

Scarecrow: I haven’t got a brain… only straw.
Dorothy: How can you talk if you haven’t got a brain?
Scarecrow: I don’t know… But some people without brains do an awful lot of talking… don’t they?
Dorothy: Yes, I guess you’re right. …

Wizard of Oz: Why, anybody can have a brain. That’s a very mediocre commodity. Every pusillanimous creature that crawls on the Earth or slinks through slimy seas has a brain. Back where I come from, we have universities, seats of great learning, where men go to become great thinkers. And when they come out, they think deep thoughts and with no more brains than you have. But they have one thing you haven’t got: a diploma. …

Scarecrow: The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side. Oh joy! Rapture! I got a brain! How can I ever thank you enough?
Wizard of Oz: You can’t.

Add to that that they are clueless about systems of any sort, much less anything as complex as a biosphere or a market.

They “mean well”, but they are not blameless – 94% of Lenin’s Bolsheviks thought he was worth following. He, like the statists in charge of environmental wackodom, intend every negative consequence. You’ve got to completely destroy any vestige of the existing order to ensure the revolution’s survival. The logical conclusion is that humans have to go.

It is an example of political manipulation of a market by the intelligentsia leading the clueless, though it’s difficult to tell them apart.
