Philp Lymbery head of the estimable British charity, Compassion in World Farming, sounds the alarm about the arrival of mega-farming in his remarkable new book Farmageddon (co-written with the journalist Isabel Oakeshott). It is not a vegetarian rant. It is not anti-meat. But it is an unforgettable indictment of the new hyper-industrialised agriculture originating in the USA which is now spreading around the world.
