The American comedian-rapper released the song and the accompanying animated video on Friday -- just three days before Earth Day.
Produced by Benny Blanco and Cashmere, "Earth" is a desperate call to save the environment, advocating for climate-change action. This call to action features the vocals of more than 30 A-list artists, including Justin Bieber, Ariana Grande, Leonardo DiCaprio, Sia, Wiz Khalifa and Ed Sheeran.
Lil Dicky also unveiled the single's accompanying animated video. Directed by Nigel Tierney and Federico Heller, the visual sees the guest artists voicing various animals around the world -- with Halsey impersonating a lion cub and Charlie Puth playing a giraffe. The rapper also hints at Kanye West, whose avatar is voiced by comedian Kevin Hart.
In an interview with TIME magazine, Lil Dicky -- born David Burd -- explained the genesis of "Earth": "The idea didn't start out as this grand thing. It really kind of started out as, 'I love animals. I'd love to make a song where different artists play the role of different animals'."
"As I started playing with it, I had this very vague understanding that there was an environmental issue on earth. I didn't know the details, and as I did my research, I was just blown away by the facts at hand .... What started as a silly joke of an idea along the way became the most important thing I'll ever do", he added.
A portion of the proceeds from the song, video and related merchandise will go to nonprofits advocating for climate change, including the Quick Response Fund for Nature and the Carbon Cycle Institute. Lil Dicky also partnered with the Leonardo DiCaprio Foundation to select the NGOs to donate to.
In addition, the rapper created a dedicated website to educate fans about climate change and means of action: https://welovetheearth.org/
