Sheryl Crow Conserves Toilet Paper?

It appears Sheryl Crow is going ultra-granola and wants to save the Earth one toilet paper square at a time. Sheryl recently proposed “a limitation be put on how many squares of toilet paper can be used in any one sitting” and perhaps, get this, “just washing that one square out.” She doesn’t think we need to pass a law, just brainwash us into her civil obedience.  Here is specifically what Sheryl crowed:  

Although my ideas are in the earliest stages of development, they are, in my mind, worth investigating. One of my favorites is in the area of forest conservation which we heavily rely on for oxygen. I propose a limitation be put on how many squares of toilet paper can be used in any one sitting. Now, I don't want to rob any law-abiding American of his or her God-given rights, but I think we are an industrious enough people that we can make it work with only one square per restroom visit, except, of course, on those pesky occasions where 2 to 3 could be required. When presenting this idea to my younger brother, who's judgment I trust implicitly, he proposed taking it one step further. I believe his quote was, "how bout just washing the one square out."
