Birds Do It

France has come up with a unique way to teach and motivate people to pick up and properly dispose of their garbage---do as the crows do. In short, if crows can do it, why can't we do it. This could well succeed if, at the risk of sounding pavlovian, we would reward people with let's say, for example, a piece of chocolate or possibly 5 French fries whenever some trash is placed in a trash can.
Or, since we are likely more intelligent than crows, we can just be Kantian and dispose of trash because it is categorically imperative that we do so.:dry:
