Ethical issues in the release of animals from captivity

For the general public, there is an intuitive appeal to an animal's living in the wild rather than in captivity. Rarely is it an appeal informed by careful scientific or ethical analysis, however. This paper discusses how animal release projects ought to be conducted, guided by the question, "what are the duties of humans toward animals that are to be released?" It studies the ethical responsibilities of caretakers, practical elements of a responsible release, and proper selection of candidate animals for release, and what marine science tells us about how best these requirements might be achieved
