Smoky Pittsburgh at midday in the 40s.

It's stunning to look at pictures of American cities before we got serious about curbing air pollution.  A heightened environmentally sensibility and the Clean Air Act has made a big difference in the quality of the air we breathe. 

Then again, it only takes a wildfire or two to bring the smoke rolling into our communities today.  And other parts of the world face air pollution on a daily basis. 

Beth Gardiner gives us a world tour in the book Choked: Life and Breath in the Age of Air Pollution.  The author talks about clean air and global attitudes toward it.
