Animal rights is the idea that some, or all, non-human animals are entitled to the possession of their own lives and that their most basic interests—such as the need to avoid suffering—should be afforded the same consideration as similar interests of human beings. Advocates oppose the assignment of moral value and fundamental protections on the basis of species membership alone—an idea known since 1970 as speciesism, when the term was coined by Richard D. Ryder—arguing that it is a prejudice as irrational as any other. They maintain that animals should no longer be viewed as property or used as food, clothing, research subjects, entertainment, or beasts of burden.
