Norway - unique on its own

Recent news says that Norway is the cleanest country after Finland. It is not clean without cleaning. You can see the second picture which is loading the trash from one of the streets at Oslo. Tourists are enjoying buggy ride even in these modern days (first picture), which may be clean in terms of air pollution emitted by vehicles but what about the animal dung in street if not cleaned?. Oslo is unique in the sense that it has freezing temperatures but offers tropical foods. One can even taste mango fruit (third picture). Third picture is the area of Oslo university college.
