PETA is a US group whose full name is People for the Ethical Treatment of Animals. They campaign to stop cruelty to animals: against testing on live animals (vivisection), against fur clothes, and often against farming animals for meat or using them in circuses. They are famous for loud public protests and hard-to-ignore advertisements, so people argue about them — some call them brave, others call them extreme. In English the name is said as a word, PEE-tuh, not letter by letter. News in Taiwan usually keeps the English name. (Peta as a person’s name is a different word, a rare feminine form of Peter; that is not this entry.)
