This week's Desert Island Discs castaway is Director of Friends of the Earth Jonathon Porritt. He'll be talking to Sue Lawley about his passionate commitment to the preservation of the planet, and also confessing that, even though he is seen by many as the guru of self-sufficiency and all things green, he would be totally at a loss when it came to surviving island life.
