For an introduction to the problem, and to anyone who hasn't lived in a severely air polluted city, I highly recommend the documentary Under the Dome , released earlier this year and later banned in China: [this video]

on HN thread This isn't an outtake from Blade Runner – it's the real Beijing
I still remember 2001 when I first arrived at Hongkong to work. My first day at the office, I got teary eyed. I told my boss why is it so..he told me it's because of the pollution and I should drink lots of water. It is probably way lot worse now. I saw this documentary recently, [this video] it is a good watch. FYI China is also destroying marine life in the West Philippine Sea [link] [link]
