It’s hard to open a newspaper or surf the internet without hearing about “going green.” The goal is for each human being to do his or her part to waste less resources, have less impact on their environment, and be kind to Mother Nature. Though we all take steps to do our part — composting our perishable goods, recycling, carpooling — it’s time to take inventory and figure out what your environmental footprint is.

Take the quiz and test your knowledge on environmental facts, like whether buying a brand new, gas-powered car is better than driving a well-maintained old car, the environmental impact of replacing just one incandescent lightbulb for a fluorescent, and just how environmentally-unfriendly air travel really is.

After testing your knowledge, calculate your actual ecological footprint or check out your impact on bio-diversity. See how you measure up on food habits, trash generation, and energy consumption.

The results may surprise you – I know they surprised me. Though I live in an apartment building, eat little meat, and don’t own a car, my footprint is a whopping 8.52 global hectares. Learn what you can do to treat your world even better and hopefully, many generations to come will be able to enjoy the beautiful green environs that we all love.
