Popular American television series "This Is Us" is more than just a feel good comedy. The cast of the show is brimming with animal-loving, eco-conscious actors, some of whom are vegan, but all of whom are advocates for a world that is better to animals. 6 of the \u2018This Is Us\u2019 Cast Members Are Vegan or Animal Loving Advocates 1. Mandy Moore https:\/\/www.instagram.com\/p\/BkTPAHEHwBB\/ Actor and singer-songwriter Moore uses her impressive platform - on Instagram, the star has more than 3 million followers - to encourage fans to "adopt, don't shop" - choose to rescue shelter pets instead of purchasing animals from breeders or pet stores. She and her on-screen husband\u00a0Milo Ventimiglia teamed up to raise awareness about rescue dogs and the urgent need to save them. In the U.S, roughly 3.9 million dogs enter animal shelters every year. And it's not just talk; Moore has adopted dogs of her own and they've even appeared on the cover of magazine Architectural Digest. When the actor's cat passed away, Moore wrote a touching tribute online, thanking the animal, named Madeline, for "the lessons in patience, responsibility, and unconditional love." 2. Eris Baker https:\/\/www.instagram.com\/p\/Bpj9n_GnQ3l\/ Baker is just 13 -years-old but already a successful, plant-powered actor. A young vegetarian, Baker gets creative in the kitchen. \u201cI love to find vegetarian recipes and restaurants and try to recreate them at home," she\u00a0said. 3. Chrissy Metz https:\/\/www.instagram.com\/p\/BlW6RkAgBjz\/ "When one of the biggest shows on television promotes adopting animal companions from shelters, it\u2019s a big deal," wrote the world's largest animals rights organization PETA. In season 2 of "This Is Us," Metz's character Kate and her husband adopt a dog from a local animal shelter, a move that earned Metz a PETA Elly Award, which praises compassion for animals on television. Author of #1 New York Times bestseller about self-love, "This Is Me",\u00a0the actor frequently promotes causes dear to her heart on social media, such as mental health, bullying, the importance of voting, and gun violence. We wouldn't be surprised if Metz starts speaking out about animal rights, too. 4. Justin Hartley Practicing my grilling skills while making room on the grill for delicious @MorningStrFarms veggie & vegan burgers this Memorial Day Weekend!\u00a0Delicious!\u00a0#Ad pic.twitter.com\/OPk54O55vT \u2014 Justin Hartley (@justinhartley) May 22, 2018 Hartley has won the hearts of many with cute snaps of his rescue dogs that he shares online. But his compassion extends further than shelter pets; Hartley partnered with vegetarian meat brand Morningstar Farms which sees him promoting sustainable, cruelty-free vegan food to his more than 1 million followers. 5. Milo Ventimiglia https:\/\/www.instagram.com\/p\/BrmaPg-AN6U\/ Ventimiglia has been vegan his whole life, bar a few bites of meat as a teenager to see what he was missing out on. Turns out, it wasn't a lot; the 41-year-old actor has held on to his cruelty-free lifestyle.\u00a0Ventimiglia grew up in a veg-forward family with his parents being vegetarian for 40 years and even the family dog not eating meat. The star recently reached out to fellow cast member Hartley's favorite meat-free brand Morningstar Farms, requesting that they bring back their veggie riblets. "I know a couple million vegetarians (as well as myself) who would be grateful if you did. Lemme know how I can help," he wrote on Twitter. 6. Sterling K. Brown https:\/\/www.instagram.com\/p\/BpFKPltnGoq\/ Perhaps inspired by his animal-loving cast mates, Brown entered into 2018 with a mindset to do more for the planet, the animals, and his health.\u00a0On New Year's Eve 2017, the star told CNN,\u00a0\u201cMy new year\u2019s resolution is that I\u2019m gonna go vegan. Gotta give up this meat.\u201d Image Credit: This Is Us Become a CLUBKINDLY member today!
