This chapter concerns the relationship between animals and society, but mostly it is about the special claims which are made for animal's rights. This explanation of animal rights will discover many surprising incidents in the attitudes and beliefs of humans. It emphasises the situation in Britain, perhaps England is better and only refer to events in other countries if they support any case or illustrate it particularly vividly. The chapter explores the social processes and relationships which lie behind the many assertions which are made in Britain for the moral relevance of animals, and show how those relationships influence people's lives. In Britain the concern with animal's rights has been an especially widespread and lively social issue since the middle of the 1970s. The chapter presents an introductory survey of the three clearest, most influential and sustained statements of the claims of animals: that by Singer and later contributions by Tom Regan and Stephen Clark.
