“Aquaman” star Jason Momoa has shaved his beard for the first time since 2012 in order to raise awareness of recyclable aluminum.

A video of Momoa quickly went viral after it was posted on Wednesday, gaining nearly 4.5 million views.

"I just want to do this to bring awareness that plastics are killing our planet," he says in the video. "And I think I have a solution. I don't want to bitch about it. There's only one thing that can really help our planet and save our planet as long as we recycle — and that's aluminum."

Momoa is launching new line of canned water with Colorado-based Ball Corp, which claims to be one of the world's largest suppliers of metal cans, The Mercury News reported. Details about the launch are not yet available. 

Momoa said roughly 75 percent of all aluminum that’s ever been used is still in circulation today.

"You drink the can and in about 60 days, it’ll be back, 100 percent. Infinitely recyclable,” Momoa said.

The actor's facial hair was a prominent part of his performances as Khal Drogo in “Game of Thrones” and Arthur Curry in “Aquaman.”

"There's a change coming, and it's aluminum ... We got to get rid of these plastic water bottles," he said. "Aquaman is trying to do the best he can — for my kids, for your kids, for the world. Clean up the oceans, clean up the land. I love you guys."
