Sue Lawley's castaway this week is the explorer and environmentalist, Robert Swan. When he was a boy Robert Swan became fascinated by Scott's attempt to conquer Antarctica and after university he decided not only to follow in his footsteps - but go one further and travel across the Arctic as well. In 1989 he achieved his dream - becoming the first man ever to walk unsupported to both the North and South Poles.
