The 30 Cleanest Cities in the World

Ifrane, Morocco

Out of just a few African cities that can boast clean environment, Ifrane is probably the most famous one. Perched high in the Middle Atlas Mountains at an elevation of 1,665 m (5,463 ft), Ifrane has no industrial action, which is why local residents and tourists can enjoy unpolluted air and water. The city is also a popular ski resort as it gets covered with snow in winter.
