Fen, Bog and Swamp (Fourth Estate, £16.99), in which the novelist Annie Proulx (The Shipping News, Brokeback Mountain) lays bare the reality of wetland destruction and what it means for the planet, is currently Book of the Week on Radio 4. It was reviewed in The Observer on Sunday and in the Literary Review earlier this month. Proulx covered the subject of wetlands recently for The New Yorker and, I see, is due to speak to one of the magazine’s staff writers, Sarah Stillman, in a session next month at New York Public Library.
