Gr 9 Up--This updated edition of the 1989 title is aimed at serious researchers and debaters. It is a well-balanced, properly documented presentation of complicated issues and contains recent statistics and fresh material. The articles are new; however, some authors appear in both editions (e.g., Tom Reagan, Peter Singer). Five chapters cover opposing views of the following topics: "Do Animals Have Rights?"; "Is Animal Experimentation Justified?"; "Should Animals Be Used for Food and Other Commodities?"; "Does Wildlife Need to Be Protected?"; and "What Issues Need to Be Resolved Within the Animal Rights Movement?" Each piece includes a one-paragraph introduction and a question to consider, and each chapter concludes with a periodical bibliography.
