Joining Paul Henley to discuss these and other issues are Anne Karpf, a British sociologist, writer, and Professor of Life Writing and Culture at the London Metropolitan University; and Mike Berners-Lee, a writer and consultant on the environment and a professor at Lancaster University here in the UK.
