    I went to Beijing several years ago on business. By a total coincidence, it happened to be just after the Golden Week festival, which is a national holiday and businesses were closed. I expected quite a bit of smog, but when I arrived everything seemed clear. My Chinese host took me out to see the Great Wall, and it was breathtaking, and also crystal clear. I was wondering if the dirty air I had heard so much about was a myth.

    But then the work week started, and as the week went on and the factories started up again, I noticed that the air was getting dirtier. My Chinese host took me to see the Forbidden City at the end of the week, which was also extremely beautiful, but already the air was so thick that I couldn’t see the landscape anymore, only the buildings in front of me.

    Nature does a good job at cleaning the local air itself, but when we spew so much crap in it Nature can’t keep up. So, yeah, smog happens because of constant pollution.
