Air pollution is one of mankind’s biggest issues at this point in history and unless big steps are taken to reduce the toxicity of the air we breathe, we may one day find ourselves unable to reverse the damage done by our industrialization. Speaking of which, it comes as no surprise that some of the world’s most polluted cities are from Asian countries, places in which a heavy industrialization process is going on.
For instance, the World Health Organization estimates that almost a quarter million people died last year because of exposure to air pollution, almost half of which were from China. Without further ado, here are the world’s most polluted cities as far as microgram concentration of pollution per cubic meter of air is concerned.
Pakistan may have its fair share of air polluted cities, but their Indian neighbors also have plenty of problems in this department. Like most cities suffering from air pollution, Kanpur also does so because of its local factories, mainly the leather industry it is famous for. The city of Kanpur registers an annual figure of 209 mcg/m3 and has been rated as the second most contaminated city in India.
