In reply to SteveSBlake:
Just come back from Corsica, the Corsicans seem to pick a bush or thicket at the beginning of a walk and everyone uses that as the toilet, there is a little toilet roll involved. There is no other litter, anywhere. At first I found the toilet arrangements odd but there is no plastic, it's all biodegradable, unobtrusive, no buildings, no water treatment, smells no worse than most public toilets , I began to warm to their system, apart from the ' designated ' area, the country is spotless.
