I was over there about 6 years ago. Smog was awful!
Huh, about 6 years ago I lived in Bakersfield Ca... and air quality levels were SO bad (farming ain't all nice) it was said that walking a mile would be the equivalent of smoking a pack of cigarettes to your lungs.
Even on nice days, we dare not open the windows.
Hubby had to go to work and suffered all kinds of shortness of breath and using inhalers facing pneumonia at least once per year . Since moving out of the awful air of California's central and southern San Joaquin valley... he no longer has those breathing issues!
Unfortunately, most my birth family was raised in California farming communities... and many have faced pancreatic cancer, stomach cancer, breast cancer, and even one of my cousins who never smoked nor exposed to second hand smoke by parents got lung cancer in his early 30's!
It seems so easy to point fingers at other countries when we may not realize just how bad things really are in our own.
I feel worst of all for the Chinese (on the surface anyways, just to keep it light hearted)... for not having access to the BYC community for their support!
While I may not agree with limits being set on how many offspring one family can have... I also understand that over population IS a real concern... and Earth cannot sustain an unlimited population... Doctors and science have helped to seriously increase our numbers. Air won't get better on it's own.

(and this despite my mostly conservative views).
ETA: Air quality actually measured HIGHER than Beijing for several days... and driving down into the valley from the hills you could see the blanket of dirt and smog hanging on the valley floor.
