PETA (People for the Ethical Treatment of Animals) is the world's largest animal rights group. Stretching the envelope of concern for animals further than traditional animal welfare groups that accept human uses of animals, PETA steadfastly advocates for animal liberation from human interference and maintains that animals are not ours to eat, to wear, to experiment on, or to use for entertainment. While they acknowledge there is much work yet to do to reduce the suffering of animals worldwide, PETA takes pride in the strides they have made toward improving the lot of many animals as the group celebrates its 25-year anniversary this year. PETA's and Ingrid Newkirk's contribution to the animal rights movement has spawned legions of animal advocates and pushed many animal welfare groups to take a more hardline stance against animal exploitation. In support of her new book, "Making Kind Choices", Ingrid Newkirk spoke and signed copies at her only appearance in San Francisco. She strongly encouraged everyone to make full use of all of PETA's copyright-free materials at their website and to request any printed materials they have to offer. From video at PetaTV to CD-ROMs, from pamplets to other materials, PETA offers information on virtually every aspect of the human use of animals and its ethical, health, and environmental ramifications.
