Organ Farm is a 3-part investigation into xenotransplantation (cross-species transplantation) using organs from animals for transplants into humans. A World Apart reveals exclusively the super-clean, bio-secure air-locked world of genetically modified pigs carrying humanised organs, for animal-to-man transplants and witness for the first time the extraordinary birth, life and the 'harvesting of organs' from these animals, bred to produce spare parts for man.
