MrBeast is YouTube royalty: with more than 100 million subscribers, he has legions of fans around the world, in awe of his elaborate stunts. He is one of the highest-paid stars on the platform - and yet, the American YouTuber says he wants to use his platform to “make the world a better place”. He has thrown his weight behind two viral environmental campaigns: #TeamTrees and #TeamSeas. Together, they have raised more than 55 million dollars to plant trees and remove plastic from the ocean. MrBeast’s supporters say he has energised a “new generation” of climate activists, but some experts have doubts: they have questioned how much of a difference these campaigns will actually make. Do they have a point?
