Anna has joined academics from Cambridge University and a group of farmers to see how they are hoping to tackle the dilemma of growing vegetables without drying out lowland peat lands, which can release carbon into the atmosphere. And staying on this theme, an agricultural university is experimenting with methods of raising beef with the lowest possible carbon footprint. Nick Allen the Chief Executive of the British Meat Processors Association gives his view on whether the resulting meat will be welcomed by supermarkets, or not.
