John and Margherita are in Cornwall, where John attends a food festival with a difference. Over four nights local chefs will cook up 12 farm feasts for 1000 guests, all from one red devon animal. John meets the 1000 Mouths festival organiser Steve Chamberlain, to hear that every single bit of the animal will be used with nothing going to waste. Margehrita meets author Chrissie Gittins who's on a mission to stop wild words disappearing from children's vocabularies. She also visits a vineyard that came about by accident, when the owners discovered the ground was better for vines than for farming. We also profile Cornish artist David Hosking who returns to the farm of his birth for the first time since leaving 45 years ago. And Adam finds out if soya could be the crop of the future for British arable farmers. Tom's looking at calls to suspend public rights of way, because of the rising number of dog attacks on livestock, but how will it affect our right to roam?
