What mark would you award us for our stewardship of the Earth so far? B minus according to the Archbishop of Canterbury. In this week's show, Mike sits down with Dr Rowan Williams to chat about faith and the church's role in helping protect the environment.

In a wide ranging interview, the symbolic head of the Anglican church discusses the world's population and our urge to consume. He also admits his own organisation must do more to encourage companies to adopt environmentally-aware policies by flexing its considerable financial muscle. The Church of England has billions of pounds invested in some of the world's largest companies.

Also in the show, we hear from a builder in Cape Town who's constructing upmarket villas and offices out of waste materials destined for landfill, and Mike invites a chemist round to his house to learn about how to turn it into a carbon-eating machine - it's all to do with "living" paint.
