yes, mindfulness is very important when it come to the realization of what exactly we are putting into us. We kill to survive. Any animal does (to my knowledge). But we should also have the necessary respect for the thing we have to kill. The question I always had, before I turned to vegetarianism for beliefs, ethics, and climate was one hard one to answer: Is it better to kill 100 chickens or one cow and use it completely? Especially when trying to see it from all 3 prior viewpoints. But in this day and age, where we are unable to raise our food ourselves, I just think that we should all use our resources very efficiently, and change our future to be sustainable.

And just as a disclaimer, I don't promote vegetarianism, I personally don't care what you eat, since it's such a personal thing. Live your life, just be diligent about it. So many people run on autopilot nowadays and sadly, it shows in my humble experience.
