Matt Baker and Julia Bradbury head for Oxfordshire, where they find out about the ancient art of thatching, and get a bird's-eye view of the landscape from a microlight. John Craven investigates the environmental effects of fish farming, and asks what is behind the decline of wild salmon and trout in Scottish rivers. Adam Henson faces a battle against the weather down on the farm as he gets in the harvest, and Katie Knapman meets a group of homeless people who escape life on the city streets by working on a farm in Sussex.
