Right

Somehow that doesn.t sound correct with "dangerous air quality". Sorry Jay
A number of years ago I was visiting friends who were staying on the 14th floor of an apartment block overlooking the ocean. As the sun slowly sank in the west, we all could see the reddish smog inversion that was level with the 12th floor of the building.
Now with regards to your response re dangerous air quality, a photograph does not do it justice because of the one-eyed view of a camera when compared with a person using their two eyes to see. If you want to see the difference, simply close one eye and see how that changes your depth perception. My son only has sight in one eye and his depth perception is not as good as my fading older aged eyesight with two "good" eyes.
In Asian countries the biggest smog polluters are motor bikes. That is why electric bikes are being encouraged for use in New Deli and other Asian cities, but the Indian sub-continent population is very mobile, and their petrol motorbikes often carry the whole family on long journeys to see their relatives and families. Something that Electric motor bike are unable to do efficiently or effectively.
I have lived on the Indian sub-continent for many extended periods over the past 26 years. I believe that my experience gained over the past 26 years does qualify the understanding that I have gleaned from my many visits over the years of the smog that floats above and over very large cities in the Indian sub-continent and what happens when "bands" that disrupt the normal activities of the population does with respect to air quality.
If you are going to be judgemental of my experiences here at home as well as in the Indian sub-continent, then please back it up with facts that shows that what I have posted is incorrect and not just your opinion.
