Rwanda has become one of the cleanest countries in the world — as clean as Switzerland — thanks to new laws requiring every citizen to pick up litter.

President Paul Kagame decreed one morning each month in the capital city of Kigali and around the countryside, to be a public clean-up day.

The last Saturday of every month, dignitaries, even the president and his cabinet,  participate in the litter collection.

Additionally, plastic polythene bags are banned in Rwanda, which cuts down the trash. And, in Kigali, littering anywhere is a crime.
