A Swedish company has come up with a rather clever way of curbing litter by training crows to collect discarded cigarette butts. The novel concept is reportedly the brainchild of Christian Günther-Hanssen, who formed the business Corvid Cleaning to put the plan into action. Currently being tested out on a small scale, the idea relies on the birds being rewarded with a treat when they pick up cigarette butts and deposit them in a small machine which dispenses the well-earned snack. Should the trial prove successful, Günther-Hanssen hopes to expand the operation throughout the city of Södertälje, which spends around $2 million a year to keep their streets clean.
