This book, written by leading academics and activists, examines the development of animal rights over the past two decades and asks where the issue goes from here. The contributions cover animal rights philosophy, strategies of the animal rights movement, the treatment of animals in specific contexts and the political arena within which animal advocates must operate. The unifying theme is provided by an emerging debate about the future direction of the animal protection movement, and, in particular, about the utility of using rights language as a means of achieving further progress.
