Renowned film director James Cameron has had enough of climate change deniers. He and his wife Suzy are leading a charge toward plant-based eating in efforts to reduce the dramatic carbon footprint that meat protein creates.

In a new interview with Variety, the couple said they’re investors in the plant-based company Verdient Foods and contribute to numerous eco-causes, including Global Green and Oceana.

“People need to wake the f–k up,” James proclaimed. “We’re going the wrong direction as fast as possible. I like to say that we’re like Thelma and Louise. We’re driving straight toward the canyon at 90 miles per hour with the radio cranked up and the top down.”

James said they’re taking drastic steps because “we felt that was one of the least well served, least understood, and biggest, most important ways that we could effect change.”

He also touched on the future of renewable energy and transportation.

“We tried to find something that was less well understood and was a major lever that could effect change,” he said. “Food is a good one. It’s probably the second-biggest one. Well ahead is transportation. We all drive around in our Teslas and our Priuses and think we are doing a great job, but really we’re all assuaging our liberal guilt. The real solution is: change the way you live.”

“Look at the amazing success of Beyond meat and the stock market,” Suzy added. “I mean, it’s not a trend — it’s actually the way the world is going. If you look at what the beef industry is investing in and what the dairy industry is investing in: They’re investing in plant-based milk and cheeses and yogurt and meat products.”
