Songstress Sheryl Crow has been trying to raise awareness for global warming from going on tour in an eco-friendly, biodiesel-powered bus to her latest "Spare a Square" campaign. Crow is trying to encourage people to use less toilet paper in an effort to support the environment. She's reaching out to her fans, asking them to use "only one square per restroom visit, expect, of course, on those pesky occassions where two to three could be required."
It's nice to know celebs are using their fame to help promote a greener world!
