High Quality Content by WIKIPEDIA articles! Animal rights, also known as animal liberation, is the idea that the most basic interests of non-human animals should be afforded the same consideration as the similar interests of human beings. Advocates approach the issue from different philosophical positions, ranging from the protectionist side of the movement, presented by philosopher Peter Singer—with a utilitarian focus on suffering and consequences, rather than on the concept of rights—to the abolitionist side, represented by law professor Gary Francione, who argues that animals need only one right: the right not to be property. Despite the different approaches, advocates broadly agree that animals should be viewed as non-human persons and members of the moral community, and should not be used as food, clothing, research subjects, or entertainment.
