As I walked across the incredibly littered campus today, it occurred to me that what the world needs is a deposit on cigarettes.
Charge a deposit of a quarter per cigarette (or the worldwide equivalent). If you want to avoid paying the deposit, you have to bring in 20 butts per pack. Whoever collects the taxes on cigarettes would provide retailers with appropriate containers and empty them out periodically.
Just think how fast the ground would be de-littered if the butts were actually worth something.
