I accept nature, thus I am not consuming living creatures. When it comes to health, I had terrible health problems before I stopped eating animal products. I feel much better right now and I don't need any doctor or scientist to prove this as I am the proof itself. I am not living in a primitive tribe, I have better understanding of the planet as a whole other than people from past + their way of getting the "food" was completely different and didn't cause as much insane damage as it is causing right now.
