Biocapacity measures how much the environment can produce compared to how much waste it can absorb. If everyone on the planet lived the way North Americans do, it would require the biocapacity of five Earths to sustain it. North Americans consume Earth's natural resources faster than they're replaced. And some resources can't be replaced at all. European lifestyles are slightly more efficient but still not sustainable: they would require the biocapacity of three Earths.
