Justin Bieber stars in New PETA ad. Bieber, the Canadian teen singer with his hit single “One Time” is anything but your average 15-year old. Thanks to his popular YouTube page, he went from posting homemade videos of himself covering the songs of his idols to making a decision most teens wouldn’t be able to handle—who to sign with … Justin Timberlake or Usher?

Between trips to the studio with Usher and preparing for the release of his debut album, My World, Justin took some time to talk to Peta2 about the other thing that means as much to him as singing: Compassion for animals.

Justin’s compassion started at home with his beloved pooch, Sam. Says Justin, “We moved to a city where we didn’t really know anybody, so I kinda wanted a friend around. And Sam was kinda like that friend.”

Justin also encourages his fans to adopt from animal shelters. Justin says: “My Dad and I used to go and hang out … just go and visit the different animals and stuff. It’s really important that people adopt. I really encourage going out to an animal shelter or a place where you can get a dog that has been abandoned or doesn’t have a home.” Knowing that, it’s really no surprise that Justin and a furry friend named Bijoux can be seen in the newest PSA for peta2 posing next to the tagline “My World Includes Compassion for Animals. Yours Should Too.”

Justin’s right, everyone’s world should include compassion for animals. You can make a difference, just like Justin!
