In an article for The Guardian, Oliver Wainwright steps "inside Beijing's apocalypse": the poisonous, polluted atmosphere that often clings to the Chinese capital. He explores ways in which those who live in this metropolis have started to redefine the spaces they frequent and the ways in which they live. Schools, he notes, are now building inflatable domes over play areas in order to "simulate a normal environment." The dangers were made clear when "this year’s Beijing marathon [...] saw many drop out when their face-mask filters turned a shade of grey after just a few kilometres." Now, in an attempt to improve the living conditions in the city, ecologists and environmental scientists are proposing new methods to filter the air en masse. Read about some of the methods here.
