Remember Sheryl Crow telling us a few weeks ago that we should combat global warming by using only one square of toilet paper in the bathroom (which prompted the classic Mark Steyn line that the new slogan of Left is apparently, “All we are saying, is give one piece a chance”)?

Crow later said she was joking, but the Worldwatch Institute isn’t. In the latest issue of their magazine they argue that Americans, with only 5 percent of the world’s population, consume something like 25 percent of the world’s toilet paper. Or something silly like that. Sayeth Worldwatch: “the reality behind the tissue’s consumption is no joke.”
