I visited Paris a couple times and travaled across Tunisia and it is not even close. All three north African countries I've visited (Morocco, Tunisia, Egypt) are littered (mostly plastic) but Tunisia shocked me the most: plastic garbage is everywhere from tourist attactions (e. g. Roman runis) and beaches to the remote desert. One of sceens which shocked me the most is when a young man drove a wheelbarow full of grabage just outside a village and dumped content to be spread by wind across the desert.
