I had long lost track of this site, but found it once again! From EarthDay is a carbon footprint calculator. They call it the "Earth Day Footprint Quiz". You answer a bunch of questions and it tells you, based on how you live your life, how many planets we would need to support everyone to live like you do.
I remember taking this quiz a long time ago, and its a shame I didn't keep the results in some way. It would be interesting to compare them to today.
My results today were:
TOTAL FOOTPRINT 18 IN COMPARISON, THE AVERAGE ECOLOGICAL FOOTPRINT IN YOUR COUNTRY IS 24 ACRES PER PERSON.
WORLDWIDE, THERE EXIST 4.5 BIOLOGICALLY PRODUCTIVE ACRES PER PERSON.
IF EVERYONE LIVED LIKE YOU, WE WOULD NEED 4.2 PLANETS.
4.2 planets! Ouch. On the other hand, I'm lower than the average in my country, but does that say anything when I'm essentially comparing myself to my iPhone loving McMansion living Hummer driving McDonalds eating fellow Americans?
Then again, how is it possible to live with only one planet? Apparently you have to be married and live in a house under 500sqft with no running water or electricity, walk to work, grow your own vegetables in your back yard and become a vegan. We really conserve in our house, but I don't think I could sacrifice that much!
Take the test and see how you do!
