It seems Justin Bieber has finally found his "purpose" -- combating air pollution!
The 22-year-old singer took to Instagram to spread the word about the quality of air in Los Angeles while on a hike on Friday, with a shirtless selfie and a medical mask.

"Air quality in la," he captioned a shirtless shot of himself wearing the mask over his mouth. "good thing I wore my mask !!"
It seems the Biebs figured out how to properly wear the mask just in time to take a little break from his hike. Moments later, he posted a photo of himself wearing the mask while writing in a notebook, presumably jotting down lyrics to his next single about the environment.
With a busy tour schedule and a new single, Bieber just isn’t down to catch anything besides Pokémon.

Earlier this month, the "Sorry" singer and his pals played the popular game with a crowd of other Pokémon trainers in the streets of New York, and while he wasn’t wearing a mask, he still went completely unrecognized.
