People leave theyir cigarette butts EVERYWHERE. I mean I used to smoke, and still do on occasion...but it's ridiculous. Those things can't be biodegradable...
In the financial district of London (or "the City" to Brits) many of the offices have little "butt bins" outside offices and they actually seem to be effective, especially since the smoking ban in offices came in. Unfortunately, what is not so effective is the same thing for chewing gum. No matter what they do to try and solve the problem there's still millions of squashed chewing gums on the streets of London.
Someone in London is really droppin' the ball, entrepenuer-wise. I used to see this in New York all the time. So paid a couple of "homeless" gentlemen to scrape it up for me. You run that stuff through a press, sprinkle a little sugar on it, re-wrap it, and you can sell it again! Edit: To Pete, it's Irving Mainway, inventor of the "Johnny Invisible Pedestrian" halloween costume.
