Guess what's trending on Twitter this afternoon?
The disappearance of a beard.
It belonged to actor Jason Momoa, whose star exploded in the hit film Aquaman.
He decided to shave the beast off to promote "infinitely recyclable aluminum".
"I just want to do this to bring awareness that plastics are killing our planet," Momoa explained on YouTube.
The solution, in his mind, is to recycle. And that means drinking fluids in cans, not plastic, because aluminum is 100 percent recyclable.
