A Point of View - The ecological sublime

Alain de Botton gives a philosopher's take on our ecological dilemmas. He argues that fear of environmental destruction has changed for ever our relationship with nature. Far from being a threat, it is now something to be pitied and protected. There are also changes in the way we view ourselves. As we take a trip to Florence to see some Titians or run water to brush our teeth, we're being asked to reconceeve of ourselves as unthinking killers. Producer: Adele Armstrong.
