The animal rights movement, sometimes called the animal liberation, animal personhood, or animal advocacy movement, is a social movement that advocates an end to the rigid moral and legal distinction drawn between human and non-human animals, an end to the status of animals as property, and an end to their use in the research, food, clothing, and entertainment industries. The argument from marginal cases is often used in animal rights advocacy which asserts that if certain humans with limited cognitive capacities are granted moral consideration, then non-human animals, who may possess different forms of intelligence or sentience, should also be afforded similar negative rights and moral consideration.
