With the argument of how Pixie Dust is made, (slaughtering pigs),I think that we should ask ourselves, what do we do with pigs normally? We eat them, well at least for the most part. Why not use them to help people grow back limbs? It's helping other people. I love animals to death. I hate seeing them in pain, and I can't kill an animal. But I also have to remember that God put animals on this earth for a reason. He put them here to help us humans. If it came down to being able to save a pig or saving one of my limbs...the pig is going to be dead.
