White Noise
That is the same uneducated reasoning that the HKG government hope the masses will believe. Looks as though its working with some.
The old folks in HKG, which those figures are based on, spent 70 of those 80+ years living in clean air. Pollution, like smoking, does not kill you instantly. It is the younger generation who are screwed. It would not surprise me if over the next 10 years HKG drops 10+ places on that list. By the time kids today are in their 60s if nothing is done they will be nearing the life expectancy for HKG and most other areas that have to live in the polluted filth we have for air.
