In 1995, there were a series of terrorist bombings and most of the bombs were hidden in metal garbage cans. So the Paris officials removed all the metal cans from the streets, Metro stations, etc. Their solution was to install green metal stands to hold transparent plastic bags—pretty difficult to hide bombs in a clear bag. These are everywhere all over the city so there's no excuse for dumping trash on the streets.
The little green men drive around in their little green trucks all day and night constantly exchanging used green bags with new green ones. Very efficient as long as the Parisians use the bags… Cute brooms, too, don't you think?
