The organization also sang her praises when Munn spread the word about how circuses treat elephants. She explained, “They’re in these crates all day long and then they’re getting shocked and beat just so they can get up and dance around on a ball.” And in a letter to the USDA about a specific captive elephant, she wrote, “Elephants were never meant to be locked inside cramped trailers, kept in chains, or forced to walk in endless circles carrying riders on their backs.”

The same year PETA named DeGeneres its Woman of the Year, the organization named Tim Gunn its Man of the Year. The Project Runway personality narrated a PETA video about how animals are slaughtered for their fur. And he said in an interview with the Los Angeles Times, “There’s no reason to kill animals for fur. Wearing fur is like wearing a big sign reading, ‘I’m in favor of inflicting cruelty and pain on animals as a fashion statement.'” Gunn added, “Unspeakable torture is inflicted on dogs, cats, bunnies, raccoons, foxes, minks, and myriad trapped, helpless creatures in the name of fashion — yes, dogs and cats.” 

5. Kristen Bell

Actress Kristen Bell owns a number of dogs, including a special-needs pup who inspired her activism with the Humane Society of the United States. She refers to her dogs as “kids I didn’t birth.” Bell advocates for adopting, not buying, a pet. And she has raised money to care for animal rescue organizations and shelters to care for special-needs animals.

Plus, Bell has eaten a vegetarian diet since age 11 because she couldn’t disassociate “the animals I cuddled with — dogs and cats for example — from the animals on my plate.” The actress has also called on the pork industry to provide better living conditions for pregnant pigs.

Phoenix also appeared in the 2005 documentary Earthlings. According to IMDB, it “chronicles the day-to-day practices of the largest industries in the world, all of which rely entirely on animals for profit.”

And she had already talked about the fur industry. McCartney expressed concern not only about the industries’ treatment of animals, but also the environmental costs of processes, such as tanning a hide to turn it into leather. The designer produces an animal-friendly brand and doesn’t use fur, leather, or feathers. And though the brand has used wool and silk, McCartney says she has been looking for alternatives.

Though musician Sarah McLachlan might not be the most active animal activist, she deserves an honorable mention thanks to her heart-wrenching commercials for the American Society for the Prevention of Cruelty to Animals. If you’ve ever caught an ASPCA ad on TV, chances are good you’ve heard McLachlan singing “Angel.” The ads have generated more than $30 million in donations to the ASPCA.

But McLachlan admits even she finds the commercials — which feature animals in need of a home — difficult to watch. “I change the channel. I can’t take it,” McLachlan explains. She adds, “I can’t even look at it. It’s just so depressing.”
