I recently read about the amount of paper that is used to wipe our bums with. Its an enormous amount. Then I read about it here http://nakedfoodcafe.blogspot.com/2007/11/doing-paperwork.html
We have an outside dry toilet and at one point used old newspaper but it wasn't really absorbant enough so we started buying proper paper. We try and use as little as possible and encourage the children to do the same. They are pretty good but sometimes the appeal of the cardboard tube becomes too much and down the loo goes the paper!
I was sent this picture yesterday and I just had to post it. Is this the solution? :)
