Yes, in the following pictures, you see a portion of a cow bone. I recognize the inconsistency of protecting one animal while participating in the use of another one that may have been raised for slaughter. The world is filled with carnivores, predators in every available niche. The constant struggle for survival is how the incredible variety of microorganisms, plants, and animals (including people) came to be. However, we can, and should, at least ensure humane treatment of any animals that we humans use for our own purposes. We can be sure those purposes are good and necessary, and we can certainly avoid frivolous or cruel mistreatment of any creatures, including our fellow humans.
