What is your personal environmental impact? How many resources does it take to support your current lifestyle? In order to know how you can improve and reduce that amount, you need to know what your impact is right now. Discover your biggest areas of resource consumption and then learn what you can do to have a smaller impact on the Earth. There are many environmental impact calculators on the Internet, here are a few that we like:
