Simpson, who also surfs, is an ocean advocate for the UN Development Programme , a global initiative that helps countries fight poverty and inequality, so it makes sense that he captioned his video with, "Buzzin. Clean cuts for clean oceans I say!" to raise awareness to ocean health. Then, as a response to a comment from 4 Ocean — a "purpose-driven business, founded to help end the ocean plastic crisis," according to the company — he tagged the photo with #cleancutsforcleanoceans Whether Simpson planned his buzzcut specifically to bring attention to his ocean advocacy work or it was just a coincidence is unclear, but we do know that Cyrus was on hand to help before a second person stepped in to finish the job.
