Around the world the price of wool has been falling, and some British farmers say it’s been difficult to make a profit. So why do so many stay in the business? Jamie, Andrew and Angus Murray farm sheep on 2000 hectares at Sewingshields Farm in Northumberland. They show us the work involved on a typical day at shearing time, and discuss how the industry has changed over the years. Filmed, Edited and Produced by Rachel Price
