The first time I took the survey evaluating my ecological footprint, I got that it would take 3.9 earths to sustain the type of life I live.  I think the results of this was inaccurate because I overestimated how much I travel, when I live 2 miles away from the school and only travel to go back and forth to class.  I also didn’t know the answers to much of the  survey questions in both tests, so I put the average for questions I didn’t know the answers to when I most likely consume less than average.  I use about 19 tons of CO2 a year.  The second time I took the test I got 3.2 earths and19 tons of CO2 again.  I could do less with eating carbohydrates and driving  when I’m in Long Island.
