Joaquin Phoenix has linked with environmental activist group Extinction Rebellion and non-profit organization Amazon Watch for a short film sounding the alarm around deforestation and global wildfires.

“Guardians of Life,” which Variety published exclusively, also stars Rosario Dawson, Matthew Modine, Oona Chaplin, Q’orianka Kilcher and musician Albert Hammond Jr of The Strokes – all of whom play a medical team racing to save an unseen patient dying of heart failure on the operating table.

Describing the two-minute film as a call to action, Phoenix said: “I did it to raise awareness about the meat and dairy industry’s effect on climate change. The fact is we are clear cutting and burning rainforests and seeing the negative effects of those actions worldwide. People don’t realize there’s still time, but only if we act now and make sweeping changes to our consumption. We can’t wait for governments to solve these problems for us. We can’t wait until the election to try to make these changes. We have a personal responsibility to make changes in our own lives and act now.”

“Guardians of Life” is the first of 12 films exploring the effects of climate change. The series is led by Extinction Rebellion and Mobilize Earth, and funded by a variety of organizations, including the U.K.-based Catalysts Foundation, as well as the global Climate Save Movement. Additional supporters include the Artists for the Amazon campaign and Environmental Media Association. Donations from the film go towards Amazon Watch and Extinction Rebellion.
