Bill Nye The Science Guy wants to teach the world about the effects of climate change, and what people can do to curb the impacts it's having on our environment.

Earth Day is just around the corner (taking place on April 22nd), and he's called in a few celebrity friends for an Earth Day-themed musical.

Jack Harlow and Justin Bieber, along with other celebrities like Charli and Dixie D'Amelio and Cody Simpson, will be joining Bill Nye as part of Earth Day! The Musical, and it's set to feature celebrities and activists sharing information about climate change.

The musical will be streaming on Facebook, and you'll also hear from entrepreneurs trying to make the world a better place, such as Symbrosia CEO Alexia Akbay, who use seaweed to reduce the amount of methane livestock produce.
