The Threat of Sensory Extinction on Earth

Did you know that, according to David George Haskell, for almost three billion years, life on Earth was almost silent? Haskell, a professor of biology at The University of the South, writes about the history and evolution of sound on Earth, in his book, Sounds Wild and Broken: Sonic Marvels, Evolution's Creativity, and the Crisis of Sensory Extinction. The book challenges us to not take the beauty of our favorite sounds on earth for granted, as climate change could mean some sounds disappear sooner than we expect. Haskell is with us to discuss. Plus, we'll take your calls.
