Children cannot play in the streets and they all have to go out with handkerchiefs to avoid the harmful effects of the air: the inhabitants of the most polluted cities in the world live almost all year long under a thick mist that does not allow them to see even the blue of the sky nor the brightness of the stars. Here we have the ranking of the most polluted cities in the world according to a study done by the World Health Organization (WHO) in 2016.
List of cities

- Beijing : In 2005 this city reached the maximum levels of pollution, according to the scale generated for its measurement, as a result of the large number of cars and the concentration of industries on the outskirts of the city.
