It depends who I'm talking to... To you, Dustin, I would say that we can just look at human biology and see that we are wired to continue our species, and that harming our planet is a threat to that, so we must prevent damage from occurring to our species indirectly. To an oil company exec, I'd say "yo dawg, that money ain't gonna do shit for yur grandkids if they get asthma!" Thus far though, I think the US and Europe are doing a good job, China and India are fast becoming the new grim reapers of the world.
