As one of the wealthiest countries, Switzerland seems to be the least polluted country in the world in 2018 as well. But it is not all sunshine and rainbows there as well. Around 1,500 people in Switzerland die annually from some of the diseases caused by air pollution in this country. That makes 18 in 100,000 people having health issues caused by the pollution.
