I firmly believe that if genetic engineering were to become legal, it would jeopardize the human race in the sense that we would no longer be unique and different beings but all the same exact creature. In addition, altering a baby's life can be dangerous to the baby itself, people will abuse this supposedly magical technological advance called genetic engineering and things could get out of hand. It is wrong to tamper with a baby's life in such a way. With current knowledge, this must be done in the early stages of development. This technique is already used in all kinds of organisms but its use on humans is forbidden by the United States, England and most western countries.
Science is the study and theoretical explanation of natural phenomena in an orderly way.
How ironic, the ability to genetically engineer your children before they are born appears extremely unnatural to me. Yet, at the same time, I believe that the baby fetus was put there naturally and should not be played with. It should be left to grow and form on its own. And, it is safe to say that there likely would be many cases in which the baby fetus was altered with to better the child in some physical manner and in the end, the child would be born as a deformed mutant from being altered from its original form. For example, genetic engineering on mice is currently only about 5 percent effective and sometimes produces deformed animals.
