Johannesburg has an annual mean pollution per city of 44 micrograms per cubic meter, according to the World Health Organization.<p>My first reaction: "WTF? it's not that bad. There's so many trees here you feel like you live in the forest."<p>My next reaction: "Oh yes, the +- 2 million people driving in shitty cars that continually shart out visible carcinogenic gasses, because they refuse to maintain their vehicles."
