Voluntary Human Extinction?

I have to say I've thought about the whole "decrease human breeding" angle before, but not to the point of "extincting" ourselves. These tree-huggers don't seem to understand the simple fact that this planet will fuck itself eventually, with or without Homo Sapians. As much as we may like the planet, Earth's ecosystem is not "perfect." It just happens to be habitable.

Yep, this is a knock-off of those people that drank the poisonous kool-aid and wore the NIKEs trying to catch that haley comet, or whatever.
