Charlotte Smith and Matt Baker are back on Jersey for a second visit to the sunny channel island. After a dramatic entrance via the sea, they discover how people power stopped development on Jersey's sensitive coastline and why the battle is on to save the island's puffins, which are on the brink of extinction. Matt discovers the healing powers of surfing, and we meet the rugby-playing mates who decided to try making their own sea salt after running out of the stuff at a beach barbecue. We also catch up with the Power Rangers, young environmentalists doing their bit for the island. Adam Henson takes some pigs to school, and Tom Heap investigates how the UK's worst ever avian flu outbreak is devastating some of our most precious seabird colonies and could pull the shutters down on British poultry farmers once again.
