Depressing Airs

It has been confirmed that air pollution has an influence on human depression and suicide rates (https://www.theguardian.com/environment/2019/dec/18/depression-and-suicide-linked-to-air-pollution-in-new-global-study). Isn't it strange that the people who produce the fumes and the politicians who do nothing about it, often live in nice rural locations, leaving the poorest to the full effects of the fumes? The effect is most powerful in the USA which ranks 7th in the world for deaths associated with pollution (https://www.theguardian.com/environment/2019/dec/18/us-top-10-countries-pollution-related-deaths-study). It's the only rich nation in the top ten and has almost 200k deaths per annum from all forms of pollution (not just the air).
