Do you know what it is like to starve? At least one in ten of the world's population will find out this year. That is 400-million people. Not all will die, but all will suffer severe mental and physical damage. Children, of course, will suffer most. As one medical expert says: ' Severe shortage of food is the worst thing that can happen to any human being - it's the one thing when you clearly have no hope for the future at all.' The world's food crisis is far worse than the energy crisis-worse even than a nuclear war. Famine is not a distant problem of far-off countries, but is directly related to our own eating habits. This programme analyses how we got into this crisis and shows how certain patterns, which you may not have noticed, are rapidly changing our lives. Producer SIMON CAMPBELL-JONES
