Sean Fletcher and Steve Brown are in Staffordshire at the Manifold Valley Agricultural Show, where the focus is on encouraging young people to get into the countryside, agriculture and the show ring with their prize livestock. After weeks of preparation, will it be a red rosette for eight-year-old Owen and his Limousin calf, and how will 12-year-old Myles and his Clydesdale fare? Adam Henson finds out what he needs to do to go green on his farm, and Tom Heap investigates a toxic threat to dolphins, porpoises and killer whales.
