What's your "Environmental Footprint?"

Did you ever wonder how much land it takes to produce all the things that you use? What we eat and how much of it, how much energy we use and how much waste we produce - all of these things have an impact on the environment.

Ecologists use the term "environmental footprint" to describe the impact of our consumption on the world. Using this environmental footprint calculator, you can find out how much land it takes to sustain your existence on the planet.
