When I was in my teens, I was invited by my an uncle to watch a cattle branding - this ranch by today's terms would still be considered a sustainable, grass fed beef farm...but after watching what happens which is pretty typical, I have never eaten beef again. I won't go into details but it was a blood bath of removing horns, nuts - some young ones die because they go too far, and then all the shots, and then finally the burning brand. All the cries, blood running down their legs and faces....we are barbarians in a modern day age and should be ashamed. It would be one thing if that was the only thing to eat to survive but it's not. Those days are long gone. I respect to each his own and know it's a personal choice. But, after I saw that, I never looked back. I have recently stopped eating all chicken, even the best organic, free range. Still eat fish. Result is that I feel fantastic, mind feels sharper, more energy, don't really miss it all that much. It does require more planning and creativity but that is what this is all about - to use our imagination, develop new skills, better health, become better people because we can.
