FRASER Nelson has actually written something which I don’t think is completely bonkers: namely that some green activists will be delighted by the drop in consumption and productivity  – and, of course, the number of people in work – caused by the recession.

This is a point I made in a speech on Heathrow back in October. George Monbiot has written in eager anticipation of the downturn in an article entitled Bring on the recession. Strange how people who would normally express concerns about the economic plight of people living in the Third World, are now more concerned that the same Third World citizens are becoming richer (A Good Thing) and are therefore demanding a higher quality of life (Another Good Thing).

But let me paint you a picture: imagine if the Intergovernmental Panel on Climate Change announced tomorrow that “we got it wrong – climate change isn’t caused by man. Sorry about that. As you were.” (Now, I know that won’t happen because the IPCC were right, but bear with me here, okay?)

What would your reaction be? I know what mine would be: delight. I’d be celebrating. I’d be popping the Champagne. Celebrations tempered, of course, by the realisation that global warming is something we can’t affect and we’ll just have to deal with. But such an announcement would be good news, yes?

Well, no, not for some (probably a minority of) environmentalists. Because for them, the fight against global warming has another aim: the defeat of capitalism, of economic growth, of prosperity.

Which is why I find their arguments so nauseating. It must be lovely to be a high-profile journalist whose own income is high and reasonably secure. And it must be so easy to offer to sacrifice the jobs and the livelihoods of millions of working people for the good of the environment.

But unless we can find a way of saving the planet without sacrificing prosperity – here and in developing countries – then the fight is already lost.
