Agriculture around the world is being revolutionised by rapid advances in genetic science. Crops are being manipulated to grow where they have never grown before and given qualities they have never before possessed. Some could even be made obsolete.
Now, a new breed of biological pirates is scouring the developing world for genetic material with the potential to earn billions of pounds.
