James Cameron recently went vegan, but says his kids don't always share his commitment to animal rights and the environment.
"The kids want hamburgers and Coke because they're kids," he said in a recent interview. "But all of human consciousness is five years old emotionally. It's not a requirement to eat animals, we just choose to do it, so it becomes a moral choice and one that is having a huge impact on the planet, using up resources and destroying the biosphere."
Cameron is so devoted to his vegan lifestyle that he recently bought a 2,500 acre vegan farm in New Zealand.
