'Air: The Restless Shaper of the World'

Author William Bryant Logan will give a talk on his book "Air: The Restless Shaper of the World," followed by a book signing.

From the book description: "Air sustains the living. Every creature breathes to live, exchanging and changing the atmosphere...With the passionate narrative style and wide-ranging erudition that have made William Bryant Logan's work a touchstone for nature lovers and environmentalists, Air is-like the contents of a bag of seaborne dust that Darwin collected aboard the Beagle-a treasure trove of discovery."
