Johannesburg has an annual mean pollution per city of 44 micrograms per cubic meter, according to the World Health Organization.<p>My first reaction: &quot;WTF? it&#x27;s not that bad. There&#x27;s so many trees here you feel like you live in the forest.&quot;<p>My next reaction: &quot;Oh yes, the +- 2 million people driving in shitty cars that continually shart out visible carcinogenic gasses, because they refuse to maintain their vehicles.&quot;
