Forget 350, How about 6.5 billion?

I've been wondering for years when we'd get back to the basics:

Contraception is ‘Greenest’ Technology

U.N. data suggest that meeting [the] unmet need for family planning would reduce unintended births by 72 per cent, reducing projected world population in 2050 by half a billion to 8.64 billion. Between 2010 and 2050 12 billion fewer “people-years” would be lived – 326 billion against 338 billion under current projections. The 34 gigatons of CO2 saved in this way would cost $220 billion – roughly $7 a ton [metric tons]. However, the same CO2 saving would cost over $1 trillion if low-carbon technologies were used.(my ems)

We as a species have been scatting in our own nest for the last 200 years, and we're getting close to making our life support system(the earth's ecosystem) unable to support us. If the US had not led the world down the "human proliferation at any cost" road in the Bush years, we wouldn't have so many people competing with the rest of the ecosystem for sustenance, and trashing up the place.

Of course, if we could all use less and stop all the trashing, the earth could support more of us.

And I suppose we'll do that just about as soon as we take responsibility for overpopulating this planet.
