While we can argue about the projected impacts of man-made global warming (my skeptics site here), it is almost certain than any solution that puts a real dent in CO2 production will bar from the middle class about a billion people who are just climbing out of subsistence poverty. TJIC notes a particularly odious proposal by environmental groups to encourage human power over industrialization in the third world:
See, first world Volvo-driving environmentalists! We can help
the Third World! All we need to do is build them human hamster wheels,
so that they can set their children to work pumping water, instead of
using nasty diesel pumps (like we do here in the First World, while our
children attend soccer practice or piano lessons).
Don't miss the really awful animation from the environmentalist's site.
