#22I was fascinated to see how low New York was. Given the immense amount of car traffic, anyone have an idea as to why its so low?

It's because colder air is more dense, making it more heavy and stay closer to the ground.

#24In a world where individualism and short term profit is valued above all. What do you think happens when we buy asian gadgets on amazon with same day delivery, mindless pollution, from the first step to the last. Go out, and look at the streets, hundreds of cars with (90% of the time) a single person in it. Moving 2 tons of steel for a 80 kilos meatbag, now that's efficiency. We could almost ignore that if it wasn't…
Short term thinking? Yes. But individualism doesn't seem like the problem given China and India are more collectivist than most Western societies.
I think the commenter means that doing what's easiest or best for you at the expense of society (now or in the future). And it doesn't have to just be for yourself, it can be for your family or tribe over others, and it still has the same effect.

#25Mexico City is in rank 704, I didn't expect that. I don't know if Mexico City is doing better or if the other 700 cities are nightmares. Well at least the pollution average in the city went down from 2017 to 2018.
The ranking is just based on PM2.5 which is just one category of pollution. Could it be that the pollution there is of another type?

The problem is externalities. Not convenience.

#27Anyone knows what the major source of pollution in Indian cities is? My guess would be automobile but I'd like it to be confirmed or denied.
My guess is manufacturing plants and burning of farm fields.
Reason is i am not seeing other big cities like shanghai/Bombay etc. which would have comparable number of automobiles but smaller cities which are known to have big factories.

And the irony is that the people who have kids tend to be the ones who care the least about these things (whether because for them it's much harder to do anything about it or because they are ignorant). Talk about loving kids.

#29How widely known is it that Indian cities are so polluted? I feel like I only hear about pollution in Chinese cities. I feel like the fact that this is dominated by Indian cities would come as a surprise to many.
I don't see why anyone would expect any extremely poor, heavily populated, industrializing area to not be very polluted.

Because we've worked on improving it for a hundred years. A mixture of regulations and regulation-driven technology improvements.
