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 just 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.

The idea of awarding rights to animals has the support of legal scholars such as Alan Dershowitz and Laurence Tribe of Harvard Law School. Animal rights is routinely covered in universities in philosophy or applied ethics courses, and as of 2011 animal law was taught in 135 law schools in the United States and Canada. Toronto lawyer Clayton Ruby argued in 2008 that the movement had reached the stage the gay rights movement was at 25 years earlier.

Joey Youngman, better known by his stage name Wolfgang Gartner, is a Grammy-nominated American house music producer and DJ. Much of his music prior to 2010 was released through his own record label, Kindergarten, but he signed with Ultra Records in 2010 and Ministry of Sound in the UK in 2011.

Youngman created the Wolfgang Gartner name in late 2008 after establishing a moderately successful name as a Deep House DJ. Not wanting to be criticized for such an abrupt departure in style, Youngman created the name anonymously. Gartner's identity was revealed officially in July 2008. Youngman took the name from the coach of the Cal Poly Mustangs men's soccer team. The Wolfgang Gartner logo was created in 2010 by New York graffiti artist Eric Haze who created logos for the Beastie Boys, Public Enemy and EPMD.

Gartner hosted the first episode of MTV's dance music show "Clubland" which aired on September 22, 2011. A portion of the episode was filmed at his home in Los Angeles, where he gave a tour of his studio and introduced music videos.

Robert William "Bob" Barker (born December 12, 1923) is a former American television game show host. He is best known for hosting CBS's The Price Is Right from 1972 to 2007, making it the longest-running daytime game show in North American television history, and for hosting Truth or Consequences from 1956 to 1975.

Born in Washington to modest circumstances, Barker enlisted in the United States Navy on the outbreak of World War II. Barker worked part-time in radio while he attended college. In 1950, Barker moved to California in order to pursue a career in broadcasting. He was given his own radio show, The Bob Barker Show, which ran for the next six years out of Burbank. Barker began his game show career in 1956, hosting Truth or Consequences. From there, he hosted various game shows as well as the Miss Universe pageants. Eventually, he hosted The Price Is Right, beginning in 1972. When his wife Dorothy Jo died, Barker became an advocate for animal rights. Since then, Barker has been a long-time supporter of animal rights, and of animal-rights activism, including groups such as the United Activists for Animal Rights and the Sea Shepherd Conservation Society. In 2007, Barker retired from hosting The Price Is Right after celebrating his 50-year career on television.

Gary Yourofsky was born on August 19, 1970, in Detroit, Michigan, United States. He grew up in Oak Park. He graduated from Berkley High School in 1988. He later received a journalism degree from Oakland University.

Yourofsky traces his animal rights advocacy to the early 1990s. His stepfather was volunteering as a clown in a circus, and offered him a backstage tour. During the tour, Yourofsky saw an elephant chained to a post, with scars behind its ears. Yourofsky was shocked, "I looked into the elephant’s eyes and all I saw was sadness and despair."^{[non-primary source needed]} He left the circus when dancing bears wearing ballet tutus were brought out in front of the audience. He started researching the treatment of animals in several industries, and became a vegetarian, then a vegan.

Peter Albert David Singer (born 6 July 1946) is an Australian philosopher who is the Ira W. DeCamp Professor of Bioethics at Princeton University and Laureate Professor at the Centre for Applied Philosophy and Public Ethics at the University of Melbourne. He specialises in applied ethics and approaches ethical issues from a secular, preference utilitarian perspective.

He has served, on two occasions, as chair of philosophy at Monash University, where he founded its Centre for Human Bioethics. In 1996, he unsuccessfully stood as a Greens candidate for the Australian Senate. In 2004, he was recognised as the Australian Humanist of the Year by the Council of Australian Humanist Societies. He has been voted one of Australia's ten most influential public intellectuals. Singer serves on the Advisory Board of Incentives for Global Health, the NGO formed to develop the Health Impact Fund proposal.

Outside academic circles, Singer is best known for his book Animal Liberation, widely regarded as the touchstone of the animal liberation movement. Not all members of the animal liberation movement share this view, and Singer himself has said the media overstates his status. His views on that and other issues in bioethics have attracted attention and a degree of controversy.
