* Eugenics: There are many people who believe the human race would be better off if specific traits could be chosen and others deleted. For example, scientists could eliminate all the disease-causing genes, guaranteeing a healthy baby. They could also give that baby enhanced vision and hearing, extreme intelligence, or a supermodel’s body. This has many ethicists and theologians worried, however, for they feel that eugenics is tampering with God’s plan.

** Spare body parts: Many people like this idea because injured people would no longer need cumbersome prosthetic equipment, but could instead have a new flesh-and-blood hand or leg in its place! And this idea isn’t just limited to limbs--it includes most every organ: the heart, bone marrow, lungs, blood, kidneys, colon, and so on.
