USA
Jimmy Doherty investigates food production techniques and the challenge of feeding the world. In the USA, farmers have put their faith in new technology to increase food output.
Jimmy Doherty sets out to discover if the world's farmers will be able to feed us in the future.
Demand for food is expected to double within the next 40 years. Yet we can only grow food on four per cent of the earth's surface, the climate is changing and resources like water and fuel are under threat. Jimmy meets the men and women who claim to have new techniques and new technologies that will help meet these challenges.
Jimmy visits the USA, the greatest food-producing country on earth. The farmers have put their faith in new technology to increase food output, but is it enough? In search of answers he visits the tomato fields and bioscience labs of California, a high-output pig farm in Iowa, and gets a taste of the Wild West while herding buffalo in South Dakota. Yet it's a farm in North Carolina that offers the most surprising approach of all.
