Frozen star Kristen Bell is lending her singing voice to a much different film involving climate change.

On Monday, Netflix unveiled the music video for the actress’ performance of “Tell Me How Long” from its new doc Chasing Coral. The song, written by Dan Romer and Teddy Geiger, is about the current climate crisis and the global underwater phenomenon of the bleaching of coral reefs.

“I was moved and inspired by Chasing Coral and its message of hope for our planet’s future,” Bell said in a statement. “I feel a responsibility to care for the Earth in whatever way I can and I was honored to lend my voice to the original song. As we strive to make a better world for our children, I hope this film will ignite real action in advancing climate solutions in our global communities.”

Chasing Coral is now streaming on Netflix and is available in select theaters.
