Ironic that the article associates particulates with cars when,
nationally, the greater risk will probably be from wood-burning.

It would be interesting to see what the quality of air in a city street and
inside your average hut/house anytime from the neolithic to the 1950s before
the clean air act. I suspect today we're breathing cleaner air than anyone has
for a few thousand years. And imagine a house before electricity or gas
heated by a wood or coal burning hearth and lit by candles.

Particulates would have been much worse then, but what about NOx?

Lots more people seem to get asthma these days.
