I have a ready solution to all their problems. They should simply do what we did in Kazakhstan a couple of years ago: raise the maximum permissible exposure levels by an order of magnitude and declare all of the previously extremely polluted areas as safe. I am not sure it made the air look any different, or had any effect on my chronic bronchitis, but at least the air pollution indicators look nice: they are now permanently in the "green zone".
