Pulitzer Prize winning American author Annie Proulx talks to Kathryn about her latest book, Fen, Bog and Swamp.
The 87 year old writes about the history of wetland destruction and the role it plays in the climate crisis and says swamps can protect against climate change if we only let them.
The non fiction work presents the case for ignoring wetland destruction at our peril.
The Shipping News and Brokeback Mountain are among Annie Proulx's most well known works of fiction, both which were made into movies.
