A little bit off topic, but I came across an interesting “How much space do you take up” Quiz from EarthDay.net (basically, how much resources do you consume/waste”

http://www.earthday.net/footprint/

Accordingly to this, if everyone lived like me, we would need 4.5 planets (4.5 Earth)

Ouch.

Supposely they underestimate the results of the quiz too. Hmm…
