China is wihout doubt the world'd pollution capital!
To the point even 25% of California's smog comes from China !!
Some
wit wrote into SCMP today saying pollution is caused by us HKers ( cars, buses etc ) China is not to blame, and the wind has nothing to do with it............so how do you explain all the clear days in summer ( no cars on the road ??? ), and how do you explain Tung Chung blanketed in 5hit the last few days ( whilst central viz 10 times better ) during the arvo and nearly clear at night
