See I disgrace, go to Vancouver in Canada you won't see any chewing gum on any street. The place is beautifully clean as are most of the towns in Canada.
Use simple Market forced to stop. On the spot £200 fine would soon have pieple stop doing it. Catch 10 people a day you have paid for a few wardens there, in no time it will be stopped. If it doesn't work double the fine. Admittedly that's quite a simplistic view!
A news report on gum on every street corner in Vancouver, it happens everywhere (other than Singapore, where they simply banned chewing gum completely)...
