Unfortunately the belief that we need to eat meat for protein is a very fossilised and very ignorant belief. Congrats to James Wilks for challenging conventional "wisdom" (ignorance) and for showing how the meat industry has conned the public for decades into believing that we need to eat animals. Of course there will be a raft of criticism for this film, that's what happens when you challenge long-held beliefs, but it will bring about some radical change. I wish all 8 billion of us could watch this documentary and wake up to what we are really doing!
