Countryfile: Cornwall

Countryfile is in Cornwall, where Matt Baker tests his sea legs on the hunt for basking sharks. He finds out about the many and varied species of shark that live in these waters and scours the shore line for shark egg cases. Ellie Harrison is on the stunning Cornish headland finding out about Operation Neptune, a project set up fifty years ago by the National Trust to map the entire coastline of the UK. Today a very different map is being produced charting the sounds of the shore. Ellie also gets up to her knees in stinging nettles to dispel their bad name. John Craven explores the partnerships between local Cornish food producers and the Eden Project. Tom Heap is also in Cornwall, finding out about how quarrying the rich underground resources there could threaten precious marine life. And Adam Henson meets some African agricultural experts learning new skills in the UK
