Justin Bieber is a baboon, Ariana Grande is a zebra and Ed Sheeran is a koala bear in the wild animated music video for Lil Dicky's "Earth."

The video, which was released at midnight on April 18, features the voice talents of thirty of music's biggest stars — including Sia, Brendon Urie and Katy Perry, to name a few — and is meant to raise awareness for climate change and other environmental threats.

Appearing on Ellen ahead of the track's release, comedic rapper Lil Dicky explained that "it's all about saving the Earth."

"There's an environmental crisis going on right now. When I started making this song I didn't know all the details ... We have twelve years to completely change the way we do so many things on Earth, or the damage is irreversible," he shared, adding that he is working closely with Leonardo DiCaprio to decide where to donate proceeds from the song.
