Ep. 43 – Cynthia Barnett on our world of seashells

When We Talk About Animals

From tiny cowries to giant clams, seashells have gripped human imaginations since time immemorial. In her magnificent new book, The Sound of the Sea, journalist Cynthia Barnett tells the epic history of humanity’s interactions with shells and the soft-bodied animals who make them. These stories of how we have treasured, traded, plundered, and coveted shells reveal much about who we are and who we’ve been, both good and bad. Barnett’s deep research ranges from the awe-inspiring “great cities of shell” of the Calusa people in Florida, to the use of cowrie shells as currency in the Atlantic slave trade, to the decimation of mollusk populations due to climate change and over-harvesting. In this episode, we speak with Barnett about what she describes as our “world of shell,” what shells can tell us about our past, how they have shaped our present, and how the future of shells and their animal makers is tied to our own.
