'Dirty and ugly' city? Paris slams viral campaign

Meh. The French are mere amateurs at littering. For 'world beating' litter levels you need to look to the other side of the Channel. The UK is awash with litter and has been for years. Professional, organised group littering can be witnessed at beauty spots, in parks and on beaches, but even the everyday levels in small towns are still far more impressive in extent and in the diversity of rubbish than anything the French can manage.

Rubbish is caused by too many people in one place. Even in exceptionally clean japan where people clean up fallen leaves, there is still rubbish everywhere.
