At one time this was often how meat animals were raised. Consider that in the wild most young animals never make it to young adulthood. They sustain coyotes, wolves, bears, hawks, mountain lions, foxes, and the like. I would also add that in my experience, plants are quite aware of what happens around them. They are anything but inert.
Death is one of the mysteries of life.
Coming to terms with it is something we Pagans, Buddhists, and others must all do, in one way or another. I eat meat. I give thanks to the spirit of the animals, and the plants, that I consume, and I give thanks to All That Is, without which we would not be. That is my way. Funny, it never prompted me to take up a gun and shoot somebody.
