We were looking at this in my biology class today...I thought it was really interesting (and slightly terrifying) to see the impact we have on the Earth put on a map like this. The "quality of life" tab also has some really interesting content.
We were also talking about individual ecological footprint using this quiz: http://footprintnetwork.org/en/index.php/GFN/page/calculators/ Again, really scary. It takes 17 acres to sustain people with a lifestyle like mine, but yet with the current world population, each person only has 5 acres.
