Oh yeah, that's the other question that always bothers me about free marketism - do you just have to ignore external costs?
The environmental part of this doesn't neccessarily just mean stuff like global warming, either - it could be not chucking toxic chemicals into the water supply because it's cheaper than getting rid of them properly...
One argument would be that sensible entrepreneurs would look to their long term rather than short term investments.
Another would be that if you are rich you can shield yourself from the environmental catastrophe you have unleashed - and even make a profit it out of it! (C.f. Gary Clail's "Privatise The Air")
