More than twenty years after its original publication, _The Case for Animal Rights _is an acknowledged classic of moral philosophy, and its author is recognized as the intellectual leader of the animal rights movement. In a new and fully considered preface, Regan responds to his critics and defends the book's revolutionary position.

Since its original publication in 1975, this groundbreaking work has awakened millions of concerned men and women to the shocking abuse of animals everywhere--inspiring a worldwide movement to eliminate much of the cruel and unnecessary laboratory animal experimentation of years past. In this newly revised and expanded edition, author Peter Singer exposes the chilling realities of today's "factory farms" and product-testing procedures--offering sound, humane solutions to what has become a profound environmental and social as well as moral issue. An important (...) and persuasive appeal to conscience, fairness, decency and justice, Animal Liberation is essential reading for the supporter and the skeptic alike.--From publisher description.

Offers a forthright approach to the many disquieting questions surrounding the emotional debate over animal rights. This book includes a chapter on animal agriculture, and additional discussions of animal law, companion animal issues, genetic engineering, animal pain, animal research, and other topics.

Although release of captive cetaceans for reestablishment of extirpated populations has not yet been necessary, current releases of excess animals could provide information for future reintroduction efforts. Previously successful reintroductions have been correlated with large numbers of individuals released with a high probability of mortality . The purpose of this study was to determine factors that would increase probability of survival for small numbers of releasees. I examine ethical issues pertaining to the arguments that a minimal set of duties owed (...) to captive individuals extends to those being released. In this release, efforts to meet such duties included pre-release determination of associations and ability to forage, assessment of local dolphin behavioral ecology to best time the release and development of trained response to research vessels with remote tracking to monitor and recapture individuals unable to adapt. ;The group comprised 6 wild-born adults and 3 captive-born juvenile females. Male association patterns were recorded using focal animal and instantaneous sampling of activity state and proximity. Boat surveys of the coastal dolphin population were conducted for 27 months . Releases were tracked via radio telemetry, boat surveys and reported sightings. ;Pre-release association patterns changed during an episode of agonistic interactions and did not persist post-release. Three cases of stress-related illness associated with the shift in associations were monitored. Although soft release was timed to coincide with peak dolphin abundance, releasees did not join wild groups. Resighting frequencies of wild dolphins suggest an open population where individuals have few close associates and extensive ranges, thus it is not surprising that 5 released animals were not sighted beyond 2-4 weeks of monitoring. The only known mortality was a newborn calf. An adult male, the mother of the newborn calf, and a juvenile female were recaptured due to visible weight loss and interaction with humans. ;Recommendations include use of both radio and satellite tracking to maximize chances of relocating releasees and more emphasis on foraging ability pre-release. Additionally, further examination of mechanisms to enhance group cohesion and means of provisioning may enhance chances of survival and integration into wild populations. (shrink)
