The castaway in this week's Desert Island Discs is biologist and conservationist Miriam Rothschild. She'll be talking to Sue Lawley about her lifelong fascination with all forms of natural life, including her passion for fleas, worms and butterflies, and also how she welcomes the prospect of exile to the mythical island as an opportunity to discover and investigate unlimited flora and fauna.
