Sheryl Crow believes using less toilet paper will stop global warming.
The If It Makes You Happy singer, who spent two weeks touring the US on a Stop Global Warming College Tour, is convinced one square per visit is sufficient.
Sheryl writes on her tour blog: "I propose a limitation to be put on how many squares of toilet paper can be used in any one sitting. I think we are
industrious enough people to make it work with only one square per restroom visit, except, of course, on those pesky occasions where two to three could be required."
