Lil Dicky's environmental video clip becomes viral

A music animation clip featuring environmental personalities such as the voices of Justin Bieber, Ed Sheeran and Ariana Grande has become viral on social media.

The song, Earth, by comedian and rapper Lil Dicky, also has cameos from Katy Perry, Snoop Dogg and Miley Cyrus.

Sending to Time, Dicky – aka David Burd – said: "What started as a silly joke about an idea along the way has become the most important thing I do."

A portion of the proceeds will go to the Leonardo DiCaprio Foundation.

DiCaprio, who campaigns for environmental issues, also makes an animated appearance near the end of the seven-minute video.

In Earth has received more than 2.5 million views on YouTube since it went live on Friday morning.

Burd and his famous friends, including Halsey, Snoop Dogg and Rita Ora, urge people to fight climate change.

Hey, I'm a zebra / Nobody knows what I'm doing, but I'm pretty cool / Am I white or black? Ariana sings while Ed Sheeran, expressing an animated marsupial, adds: I am a koala and I sleep all the time / So what? That's cute / How did you prevent all those superstars from being on the song?

"It was me, my manager Scooter Braun [who also represents Bieber and Grande] and Benny Blanco, who is a real producer in every sense of the world, "said Burd. We are all so competitive people that we all kept control over who got who.

"We all had our own relationships and together, in a three-pronged attack, we had 30 artists.

Burd admits he had a hard time hearing from a well-known voice of rapper and producer Kanye West.

"I'm friends with Kanye, I played basketball with him," he said.

"But I left within three days to call Kanye on the phone and I could not contact him, he was rather inaccessible, he changed his email and his mobile phone.

"Then I contacted Kevin Hart and asked him," Do you want to play Kanye? "And he said" yes "."
