PETA opposes speciesism, a human-supremacist worldview, and focuses its attention 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.
