Therefore city dwellers are demented and rural dwellers aren't.

(And this says nothing about the effects of noise pollution or aesthetic pollution)

EDIT

Oh come on, it's the obvious conclusion. So discuss already.

One of the surprising things about visiting the mountains to do various outdoor activities in nature is how often the air quality is worse than it is at home in an urban area. A big part of this is that "home" is the SF Bay Area and we have consistent winds blowing inland from the ocean, which blows our air pollution to other people (and the air gets noticeable worse when this doesn't happen), but also the air quality is often shockingly poor in rural areas. Wood stoves, diesel generators, and the like in spots where the pollution gets trapped can do a lot even with low density.

On average the air quality is worse in cities than in rural areas, but at least in the United States the difference is smaller than you might expect. In countries that do not take urban air pollution seriously it gets very bad, of course.
