Comrades Murray,
The argument that trade and industrial development should be stopped to save the 'biosphere" is untenable. Until people's needs are met consistently and for a good while, they will not think of the biosphere when it comes to a choice. That much is perfectly clear. In fact it is this desire among the working class to satisfy the necessities of life at very high personal cost that capitalism depends on. People are so desperate that they will take wage-slave jobs and tolerate all the excesses of capitalism.
The catastrophist idea that the planet will die if free trade does not abate is, to say the least, scientifically unproved. Even if it was true it would not matter. People will develop the world right into oblivion because, right now, they have no choice but a false one. They have done it region by region and for hundreds of years. In fact some of the most rapacious and unnecessary exploitation of the biome comes from poor people harvesting things like timber or trying to farm in the rainforest. These behaviors come from a lack of development, not too much.
The question is how to handle a world of inevitable development and free trade. The WTO is clearly no way to do that, but it does no good to associate a legitimate protest against WTO policies with a protest against economic reality. Consider the choice an anti-free-trade, anti-development presents to the world: "You can have rapacious capitalism or,...." What? That majority of the world's people don't want to live like indios or peasant farmers. It's a shitty way to live. The majority of the world's people desperately want industrial development, and right now only one camp is offering that - capitalists.
Suggest a better, more prosperous, more free mode of industrial development and you'll go far. Try to involve people who are already uncertain about their futures in catastrophist hand-wringing and you will get few takers. At least, at the very least, suggest to people that it's not the WTO or nothing. It's the WTO or something much stronger.
peace
