People for the Ethical Treatment of Animals (PETA), with 6.5 million members and supporters, is the largest animal rights organization in the world. PETA focuses its attention on the four areas in which the largest numbers of animals suffer the most intensely for the longest periods of time: on factory farms, in laboratories, in the clothing trade, and in the entertainment industry. PETA staffers have had their articles and opinion pieces published in everything from BUST magazine to The Wall Street Journal, and several staffers post pieces to OpEdNews.com using this account.
