I think the fact that it isn't cheap shouldn't be that much of an issue (although I know it currently is) because the price we (not even our children) will pay because of climate change would be much higher (in pure economic costs, before we start talking about more moral and environmental costs like animal extinction).

But I think the problem is that people care about today a lot more then they care about tomorrow, or next year (and definitely more then their potential future descendants).
