They don't know it's coming. They wouldn't live at all if we weren't raising them for food. If they could be raised in humane, unlike mass production conditions, then one could argue convincingly that it's better than not doing it all from a purely compassionate viewpoint. It's still tremendously wasteful of land and resources, but that's a separate concern to address.
