The first edition of The Human Use of Animals offered the first set of case studies on animal use through sixteen original, previously unpublished essays. Whereas the first edition strongly emphasized research issues, the second edition now adds material on conversation concerns and the use of animals in entertainment, specifically cases on endangered species, zoos, circuses, and 'sport' fighting. As with the first edition, the cases are presented in an objective and balanced way that will spark reasoned debate about moral issues. Extensively revised and updated, the second edition maintains a commitment to a discussion of ethical reflection and analysis concerning human interactions with animals.
