Jason Momoa (43) cut off his famous mane and shaved his head. With the campaign shared on Instagram, the "Aquaman" star wants to draw attention to the waste of plastic.

The Hawaiian greets his followers with an "Aloha together" – and holds two braids that have just been cut off for the camera. Meanwhile, a friend puts a razor on his head. With a gust of wind, the actor is startled by the feeling on his skull - which he obviously hasn't felt for a long time.

"Shave my hair off. Because of single-use plastic," he says. "I'm fed up with plastic bottles, we have to stop it. Plastic forks, all that shit".

The plastic ends up in the ground or in the sea. "I'm seeing some things in our oceans right now that are so sad," says Momoa, pleading to his fans: "So please do everything you can to avoid single-use plastic in your life - help me".

In the text accompanying the video, Momoa summarizes the message again. "We must ban single-use plastic from our lives and from our seas. Plastic bottles, plastic bags, packaging, utensils - everything".

Momoa insists on promoting Mananalu in the video. In 2019, the actor founded the water manufacturer. The company sells water in sustainable aluminum bottles instead of plastic. For every bottle purchased, Mananalu fishes bottle-sized plastic from the oceans.

As he talks about existing alternatives to single-use plastic, Momoa holds a bottle from Mananalu up to the camera.
