Brazil

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 starts his journey in the giant of South America - Brazil. He discovers how to turn poisoned land into a powerhouse of world food production, joins sugar cane cutters to see how Brazil has replaced half of all its petrol use with biofuel, and finds a way to save Caiman alligators from poachers. In the Amazon, Jimmy meets an unlikely cattle rancher who claims he can save the rainforest.
