ecological footprint

i stumbled across this website - http://www.myfootprint.org/ which tells you about how much of the earth's resources you use. i consider myself to be an environmental person: i recycle, don't eat any animal products besides egg, dairy and certain kinds of fish, i take public transportation most of the time, i donate money to environmental charities. and if everyone lived like me, there would need to be 4.8 earths to sustain us all.
looks like i'm not very environmental, after all.
