Smog hangs over Ulan Bator – like every winter. This air pollution and intense cold is damaging the lungs of 19-year-old Tsegi. But it’s not only Mongolia’s capital: Here’s a look at some of the worst cities for bad air.

Ulan Bator is not only one of the coldest capitals on earth, it’s also a city with massive air pollution.
