You get the same trouble up bush, often around the huts were there is a long drop to use! some people just dnt care, such people should just stay at home! Its the toilet paper thats the problem, the other materials will break down over a short period of time but the paper will hang around for a long long time after. digging a deep enough hole should do the trick, and a roll of a more environment friendly paper wouldn't be a bad idea, i,ll be looking for some next time out shopping!
