Sir Paul McCartney is an undeniable legend—and we’re not even referring to that whole Beatles thing. Paul recently sat down with longtime friend and PETA Vice President Dan Mathews to reflect on their two decades of work in behalf of animals. When asked how things have changed since PETA’s inception, Paul explained, “People have been exposed to knowledge over the years and have learned what it’s about—just how cruel we as a species are to our fellow inhabitants of the Earth.”

Heather Mills McCartneyWell aware of the work that’s still ahead, Paul continued, “All of us get a little worn down by it, but the truth is, we are winning. … We are learning to understand these issues.” Who better to help others learn these issues than Sir Paul McCartney? He recently made headlines after announcing that he would never perform in China after watching footage of dogs and cats killed for their fur. “I wouldn’t even dream of going over there to play, in the same way I wouldn’t go to a country that supported apartheid,” Paul explained during a BBC news feature on animal cruelty in the Chinese fur trade. “It’s like something out of the dark ages,” he continued. “It’s just against every rule of humanity. I couldn’t go there.”

The video footage, which was shot by an undercover investigator for PETA, shows screaming cats and dogs lifted out of tiny cages with metal tongs and thrown over a 7-foot fence. A bag of cats is tossed into a cauldron of boiling water, and several other animals are brutally killed and skinned. When Paul’s wife, Heather Mills, who is also an animal rights advocate, watched the footage, she was equally horrified and issued a consumer alert about several top fashion retailers whose fur garments may be made of dog and cat fur. Shortly thereafter, she helped launch a PETA boycott against $800-million-a-year clothing chain J.Crew for reintroducing fur into its product line. After leading the boycott for several weeks, her efforts paid off—on November 30, J.Crew announced that it had ended all fur sales and pulled all fur from its racks.

Paul and Heather are also both vegetarian. In an effort to promote the benefits of vegetarianism and animal welfare, Paul wrote an open letter to KFC CEO David Novak, asking him to implement PETA’s eight-point plan to eliminate the worst abuses of chickens. Persuading KFC to take these simple steps would mean a world of difference to animals, but Paul knows that the best way to help animals is to go vegetarian.
