The second in a two part drama about global food security.
It's three years after the events of part one and a new world order is dominated by global food protectionism, an unpredictable climate and, most of all, hunger.
Phil and Sian have used the money they made to buy a farm in mid-Wales. But as an international enquiry is launched into the causes of the crash, the couple's country idyll provides little shelter from an angry world, hungry for answers.
World food security is a hot topic. Internationally, after record growth, global wheat exports have fallen by 10 per cent (2012/13 figs). Prices are rising inexorably. According to Oxfam, 800 million people are currently malnourished - a greater figure than ever before. As cereal production falls, world population numbers continue to rise, and the UN Food and Agriculture Organisation predicts food demand will double by 2030. Meanwhile world food security remains left to the volatility of the global free market.
When Greed Becomes Hunger asks whether the world can afford to trust the free market with its food supply.
