Acclaimed director James Cameron and his wife, Suzy Amis-Cameron, were championing Suzy’s 6th annual “Red Carpet Green Dress” campaign when they revealed their school in Calabasas, CA would become the first in the country to become solely vegan.

During the eco-friendly fashion event at Chateau Marmont on Feb. 19, the couple revealed that in the upcoming school season, Muse School, would be doing away with animal products and switching over to more “whole” food, according to the Hollywood Reporter.

“In the fall of 2015, Muse will be the only school we are aware of that is completely plant-based,” Suzy told a crowd, before Cameron interrupted to finish the sentence:

“Plant-based eating — meaning the meals that are served at Muse will be 100 percent plant-based. The average person would say vegan, but we say whole food, plant-based,” the Avatar director said.

He finished: “It’s about raising kids who don’t think it’s strange or exotic or worthy of a pat on the back to be doing the right thing for the living biosphere.”

The “Red Carpet Green Dress” campaign pursues eco-friendly fashion, and donates one quarter of all sales to Muse School, a nonprofit institution co-founded in 2006 by Amis-Cameron and her sister Rebecca Amis, reports the Los Angeles Times.

The school’s website reads:

The story of the MUSE school begins in 2005 with Suzy Amis Cameron, a global environmental activist, mother of five, and proud wife. Suzy and her husband, Jim, had watched their older children struggle… and sought an alternative and more environmentally aware option for their then five year old. With caring and compassionate teachers, playful classrooms, and opportunities for exploration and reflection at every turn, MUSE has become an educational oasis for parents who recognize the enormous value in kindling each child’s own unique spark. What’s more, by celebrating community and the natural environment, promoting cross-cultural experiences, modeling leadership, and illustrating that learning and teaching are collaborative efforts, MUSE School fosters graduates who become bold leaders fully prepared to face challenges, to live beyond complacency, and to embrace learning and change throughout their lives.

Amis-Cameron stated her belief in June of 2014 that one cannot claim to be an environmentalist without going vegan.

“You can’t really call yourself an environmentalist if you’re still consuming animals,” she said. “You just can’t.”
