We and they: Animal welfare in the era of advanced agricultural biotechnology

摘要

The paper discusses central moral issues raised by the applications of advanced biotechnology to animal agriculture and introduces the major ethical concepts and principles of animal bioethics. It is argued that biotechnology enables human beings to transform animals according to human needs, which blurs the boundary between humans and non-human animals in moral and biological sense. The more humans change animals, the more responsible humans are for the welfare of the animals and the greater their moral obligations. The paper introduces the main ethical approaches to animal welfare, traces the philosophical roots of animal ethics in the Judeo-Christian tradition and discusses the views of classical and contemporary ethicists such as Kant. Bentham,Mill, Peter Singer and Tom Regan. The paper explores the concept of animal welfare, suffering and rights, and the values behind Animal Liberation. Special attention is given to the animal welfare issues posed by cloning, genetic engineering and patentingof living organism. For each technology, actual or potential risks to animal welfare are identified and their moral implications are outlined. It is noted that the traditional moral principles of animal welfare, animal interests and animal rights are inadequate as means for evaluating the morality of certain advanced technologies because the technologies can change the animals in profound ways that make animal awareness too limited to give rise to claims about welfare, interests or rights. The principle of animal integrity is endorsed as an alternative better suited for evaluating the morality of advanced biotechnology.
