Lil Dicky, the white comedy rapper with questionable taste but an impressive rolodex, has come up with a millennial’s Earth Day answer to the 80s celebrity-studded, charity hit “We are the World“. Dicky isn’t tackling African famine, instead he’s come up with an oddly anally-fixated paean to the Earth’s climate and the disaster the world faces if there isn’t some collective action taken to reverse our current course of carbon emissions. To hammer this message home, and raise money for Leonardo DiCaprio’s climate change-focused foundation, the tricky Dicky with a fraught history has enlisted some very very powerful celebrity friends. DiCaprio appears in the video, as does Ariana Grande, Katy Perry, Halsey, Ed Sheeran, Snoop Dogg, Kevin Hart, Wiz Kalifa, Shawn Mendes, Justin Bieber, Miley Cyrus and the Backstreet Boys. “Like a lot of people, I had a vague idea that something bad was happening here on Earth, but I didn’t really realize how insane our climate crisis is and how screwed humanity is about to be,” the artist told Vice’s music publication, Noisey, in an interview.
