The beef industry is under pressure. Prices are low for British farmers and beef is facing a back-lash from environmental campaigners. To begin Farming Today's week about beef Sybil speaks to Professor Don Broome from the University of Cambridge who says that the environmental impact of beef comes down to how it's produced and why the effects of methane have been slightly over-stated.

Laura French who farms on the island of Rousay in the Orkneys tells Sybil that some her lambs may starve after a height restriction placed on lorries boarding their local ferry has prevented her getting her lambs to market.

Richard Westcott reports from the Anglia Ruskin University where new research shows that tiny bits of plastic in the soil can stunt the growth of worms.
