Use only one square of TP!

Crow calls for limit on loo paper

The shows include a short set from Sheryl Crow and film clips
Singer Sheryl Crow has said a ban on using too much toilet paper should be introduced to help the environment.
Crow has suggested using "only one square per restroom visit, except, of course, on those pesky occasions where two to three could be required".

So what say you fellow citizens concerned with sustainability? Is this a viable idea? LOL
