But sometimes it gets worse. This is the view from our 28th floor balcony in the Futian District of Shenzhen - on a bright day and on a "not so bright" day.
I must admit I haven't experienced anything similar yet, despite I have lived in a city with population of 5 million for many years.
Sometimes one has a feeling that there is literally no oxygen in the air. I wonder how does it feel in the inland of China?
So how bad should it get before something starts changing? I mean, how deep should be the damage for environment and health of ordinary citizens before environmental standards are effectively implemented?
