I once spent time in the Rocky Mountains. Didn't plan it very well. Ran out of food and supplies quickly. Nothing but ice and snow. Felt sorry for the critters. Got real hungry. I ate anything that ran slower than me. Felt sorry for the critters, but I had to eat. Went hunting with my dad and my uncle. Had plenty of food. Shot things for fun and didn't even eat it. I hated myself and my relatives for it. Food is relative. Food sources are relative. If you can control your resources, you can live with it. If you can't control it, you eat it. Simple.
