11 Worst Countries for Air Pollution

2. Afghanistan

Average PM2.5 pollution: 84 ug/m3

Average PM10 pollution: 268 ug/m3

With a population of over 35 million people, Afghanistan’s air isn’t as breathable as one would like. In fact, the heavy traffic congestions and the unlimited dust supply, paired up with geographical factors such as the high mountains in the area, translate into high pollution levels. The poverty rate isn’t all that great either, which means many people turn to alternatives to keep warm, including burning tires and plastic items, since they cannot afford luxuries such as electricity.
