However, these other cities don't even come close to the reality of Pohang. Just look at the satellite image below. What you see is the second largest steel factory in the world.
It's so huge that it takes up a quarter of the city. And that Mordor glow with smoke that you see on so many night-time pictures? Yes, it's all real.
For more images, take a look at Flickr here, here and here.
Of course, the steel factory is only one of many sources of pollution: there are frequent winds from over-polluted China with smoke and sand that cause breathing issues, there is constant illegal waste burning by the population... you pick your poison.
