Calculate your ecological footprint:

The average American’s lifestyle (“average” meaning “everyone’s added up and divided by the number of people” — not “normal”) requires 24 acres of land per person.  If everyone lived like that, we’d need at least 3 planets.

My footprint, based on my life right now, is 3 acres.  If I ate meat, and nothing else in my life was changed, I’d need two more acres to sustain my lifestyle.  This isn’t meant to be preachy… I’m just fascinated.
