I don't really know how I feel about all of this, since it's not an exact science at all, but I took a quiz to show what my "carbon footprint" is. I got 13 acres, which is less than the average 24 acres that most Americans have (according to the site).
My results are below...but my question is, how do they get the results and information to assume how many acres I use in my life? Take the quiz and let me know how you measure up.
(Results to show up later...)
