Someone asked me this question in the comments section of a recent post, and I thought it deserved a high-profile answer.
In the banner of this blog I refer to the “quest by the environmental left to destroy the world’s economy” through various means. I was asked: Why would they want to do that? What’s their motivation?
For me to call this the "quest" of the entire environmental left is a bit of hyperbole -- but IMO the characterization is justified because, whether consciously or unconsciously, the environmental left is aggressively pursuing an agenda that can have no logical end other than the destruction of the world economy.
On one hand, I accept at face value their claim to be motivated by concern for the environment. So much of modern civilization is based on customs, technology, etc. that the environmental left feels are harmful to the environment. AGW, real or not, is to them the golden opportunity to remake civilization into a form more to their liking.
On the other hand, many now marching under the banner of environmentalism would in a previous generation have been classified as good old-fashioned Marxists. Their true motivations are economic, not environmental. But overt Marxism is a bit out of fashion in the west, and environmentalism is quite fashionable, so what better cover can one find for one’s war against capitalism? Just think about how many people out there are saying that the only way to lick the climate crisis is to shift more and more of the economy to state control.
So, agree or not, that is why I used these pointed words in the blog banner.
UPDATE: I almost forgot the following point about how AGW is a good cover for Marxists... Think also about how many out there are preaching that the greatest moral imperative of "rich" countries is to transfer increasing amounts of their wealth to poor countries -- with no strings attached.
