Some years ago I shared a podium for several days with a vegetarian. He told me a touching story about having been a lonely boy whose closest companion was his pet dog. He said that, peering into the dog's eyes one day, he had come to see the animal as a fellow being. Soon he had applied this view to all animals, and since he could not bear the thought of eating his dog, he could no longer eat other animals. It is anatomically clear that God did not design humans to eat meat.
Slaughter is repugnant and degrading.
Raising animals for meat is inefficient and misuses available land. Animal flesh is unhealthful because it contains toxins, virulent bacteria, uric acid, impure fluids, and the wrong kinds of nutrients. Inherent in the idea that all life is sacred is the supposition that all forms of life have equal value. The natural world reveals hierarchies in the food chain, the dominance of certain species over others. The multifarious dietary practices of human populations belie the notion that humans are designed to be vegetarians rather than omnivores.
