For me it turns out that if all six billion of us lived like me, we'd need 4.9 Earths to feed, cloth, house, and transport all of us. Personally, I take up about 8.9 hectares (US average is 9.7, so I'm a little better than most of my countrymen--but not as good as I thought). "Worldwide, there exist 1.8 biologically productive global hectares per person."
