Personal Reflection on Ecological Footprint and Other Things

I filled this footprint out as is I was living in my parents house, which I currently am for the summer. Some of the water usage and conservation questions were tough to answer, but I did my best estimation. I remember my dad telling me about the eco friendly lightbulbs and the water conserving toilets. I am also a vegetarian, which lowers my footprint substantially. If everyone lived like me, we would need 4.08 earths. I wonder what the national average is.
