People for the Ethical Treatment of Animals (PETA) is the largest animal rights organization in the world, and PETA entities have more than 9 million members and supporters. PETA opposes speciesism, a human-supremacist worldview, and focuses on the four areas in which the largest numbers of animals suffer the most intensely for the longest periods of time: in laboratories, in the food industry, in the clothing trade, and in the entertainment business. We also work on a variety of other issues, including the cruel killing of rodents, birds, and other animals who are often considered “pests” as well as cruelty to domesticated animals.PETA works through public education, investigations, research, animal rescue, legislation, protests, and negotiations with companies and regulatory agencies.
