i've been hearing about this game on npr called consumer consequences. the idea is that you play a "game" and answer questions about your consumer use to see how many planet earths it would take to sustain the population if everyone on earth lived like you. i am pretty green and even with my cutbacks - i don't buy anything new, i unplug everything in my home when i'm not using it and cut my gas and electric bill in half, i buy only local and organic food - if everyone lived like me it would take 1.7 planets to sustain us. uh-oh.
here's the link. i highly encourage you to play it. it shows your score but then offers suggestions for how to improve your score/consumer lifestyle.
