Inspired by the wonderful simplicity of [Free Rice][], two guys started [OneSquareFoot.org][], a site whereby you can save acres of rainforest by answering some simple trivia questions. We all know that it’s imperative that we make a difference and save the rainforest ([we've talked about that before][]), and now you have a way to do so on your downtime, whether taking a break from work or tuning out your professor (not that we condone that). The best part is that you’ll be literally saving one of our most precious resources right where you are, five minutes at a time.
