7. Mauritius
Although the world is not that familiar with this small paradise, Mauritius gains an advantage of having less population to maintain the cleanliness of the country. Since that most countries have a population as one of the primary factors in contributing pollution, this serves an ace for them. And it’s also up to them whether to make their paradise remain a paradise or maybe in the near future, make it a disaster island avoided by most. Only a few remain to be like this, we just hope it will be better for the next generations to come.
