How much of the planet are you wasting?

For Greensboro readers, our city has about 225,000 people in it, and it really doesn't make a huge difference whether you think Greensboro's weather is more like St. Louis or Atlanta. (Having never been to either place, what do I know? I choose St. Louis on latitude grounds. When I went back and did Atlanta, my footprint only dropped by .3 acres.)

My ecological footprint is 13 acres. If everyone lived like me, we would need 3.2 planets.

(The average ecological footprint in America is 24 acres per person; worldwide, there exist 4.5 ecologically productive acres per person. So, yeah.)
