Should we develop the science of cloning human body parts? Mind you, I don't mean the cloning of an entire human being, just organs. The advantages would be vast. If someone has a bad heart, liver, lung, kidney, or some other organ, it would be possible to grow and transplant a replacement, which is genetically designed for that person. There would be no anti-rejection drugs needed. We also would not have to wait for someone to die who has donated an organ.
However, cloning is scary. Are we being like a Dr. Frankenstein here?
