This book investigates the implications of increasing applications of genetic engineering to farming - for humanity, animals, plants, and the environment in general. The book also examines topics such as the use of bovine somatotropin (BST) to increase milk production, the deliberate release of genetically manipulated organisms into the environment, transgenic animals and the patenting of animals. The book looks at the issues from the point of view of animal welfare and the point of view of science, with the debate focused by a variety of perspectives - ethical, theological, philosophical social, and environmental. The contributors are a broad, international selection of academics and professionals, including representatives of Friends of the Earth, the Foundation on Economic Trends, the European Community Concertation Unit in Biotechnology, the London Food Commission and the RSPCA.
