Millions of people around the world would be very well nourished on what we, in the West, feed to our pigs. Britain stands accused of being one of the meanest nations on earth.

Of them, 350 will die during the 50 minutes of this programme. Yet this fertile planet produces enough food for everyone. What's gone wrong?
