Blame it on the wombles if you like, but I have always found littering one of the most anti-social activities. Well, no actually the wombles thrived on litter, they could set up a colony round here. I like the Pam Ayers poem, littering, and the Flanders and Swann song Bedstead men. But their comes a point when humour and education have had their trial period.
There are powers for on the spot fines for littering - although these are such a rarity, the figures I have seen that people with these powers average less than one fine each per year.
I don't know what the answer is. It should be self evident that littering is bad. Words fail me
