In a Toronto subway train I once saw a public service ad that advised people to remove the first piece of litter that is thrown on the train. If you don't, then expect a dirty car.
I experienced the soundness of this advice for myself. My house is located on a neat and spotless cul-de-sac, in the center of which is a large round island of turf on which is a tall street-light standard. We the residents use this to have summer BBQs for the neighborhood. Many cars can park around it due to it's large diameter. On Saturday nights when one of the houses has a party crowd, visitors will sit in their cars after the party, talk and throw a couple of beer or coke cans on the island. On the following morning I would put on my garbage gloves, pick up the bottles or cans and put them in a garbage bag. I did this on a few Sundays. People soon started doing the same and soon after that they probably warned their guests about it. I have had no occasion to clear anything for years now. The place is spotless again. Don't less that first piece lie undisturbed. People will add to it and before you know it, a dump arises where there was none before.
