National Geographic has unveiled its National Geographic 33 list, honoring individuals making a positive impact on the world.

Selena Gomez is recognized for her work in mental health advocacy through her Rare Impact Fund. Björk is celebrated for her environmental activism in Iceland and beyond. The list also includes entertainers such as Arlo Parks, Don Cheadle, and Yara Shahidi, among others.

“With the National Geographic 33, we’re honoring a diverse group of changemakers, from all over the world and different walks of life, who aren’t just recognizing the urgent challenges of our time, they are taking action to address them,” said Nathan Lump, SVP and editor-in-chief of National Geographic, in a press statement. “They all share a deep commitment to shaping a better future, and in shining a light on them and their contributions, we hope to elevate their work and showcase to a wide audience the positive impact they’re making.”
