Two Dutch industrial designers Ruben Van Der Vleuten and Bob Spikman have come up with a very unique solution to litter problems of big cities. The designers propose the concept of a 'crowbar', inspired by the 'Crow Box', where crows will be trained to pick up and dispose of cigarette butts. The 'Crowbar' will also serve as a vending machine, providing peanuts to the birds after inserting butts.
Crows are one of the most intelligent and clever species in the world, and this makes them perfect for the project. Although it seems quite impossible to implement the concept due to many difficulties that would arise in the process, designers are working hard in making their unique idea a reality.
