Famous director James Cameron has been making the headlines lately for his switch to a plant-based diet, and now the filmmaker is advocating for others to make the switch as well. On October 5, pro-vegan documentary Earthlings posted a clip of Cameron on its Facebook page. In it, the director discussed how all environmentalists should be vegans. “You can’t be an environmentalist, you can’t be an ocean steward, without truly walking the walk.

According to the Food and Agriculture Organization of the United Nations, current estimates put the livestock industry’s contribution to global greenhouse gasses at 18 percent.
