Genetic Engineering Genetic Engineering Anti-technologists and political extremists misinform, and over exaggerate statements that genetic engineering is not part of the natural order of things. The moral question of genetic engineering can be answered by studying human evolution and the idea of survival of the fittest. The question of safety can be answered by looking at the current precautions of the industry. The concept that society needs to understand is that with the right amount of time and money genetic engineering will help reduce disease and save countless lives. Many people do not realize that genetic engineering plays a role in many lives through out the world. Genetic engineering includes artificial insemination, in vitro fertilization, sperm banks, cloning, and gene manipulation (Goetz 178). Synthetic insulin is now available for use to treat diabetes. This man made insulin has many positive aspects, which include its life span, cost to manufacture it, and the amount that is available. The synthetic insulin lasts two to three times longer than its natural form and costs substantially less to manufacture than to extract it from an animal, primarily pigs. One other benefit is the amount that can be manufactured. In pigs, the scientists need to wait for it to mature to extract the insulin. The synthetic source is completely man made and any amount can be manufactured in large quantities. The replication of insulin is not the only way biotechnology is being utilized. Today people receive synthetic hormones that their body cannot produce such as growth hormones, thyroid, estrogen, and testosterone. Vaccines are also another form of genetic engineering that has been used for many years. Vaccines already protect against disease to a certain extent, but for a virus like HIV, it is too risky to inject somebody with a vaccine. The reason for this is because a vaccine is a solution that contains a dead or weakened virus that has been synthetically prepared. Further work on a HIV vaccine could save many lives and possibly eliminate the disease. This biotechnology makes it possible for more people to live the lives that would not have been available without genetic engineering. Plants are also being genetically engineered. This type of genetic engineering is more commonly accepted, but why? It is no different for a plant to be able to fight off pests then it is for a human to be able to fight off diseases. This is a contradiction, because society is saying that it is all right for a plant to be genetically engineered but not a human. This new technology of genetic engineering dates back to the 1950's. IN 1951 three scientists, Francis Crick, Maurice Wilkins, and James Dewey Watson, were credited with the discovery of DNA. Later they were presented the Nobel Prize in physiology and medicine in 1962. (Lewin 1) DNA is also known as deoxyribonucleic acid and it carries a living organisms genetic code. The discovery of DNA was the very beginning of genetic engineering. Today the science of biotechnology has evolved to a much higher level, but is still many steps away from completely correcting damaged or diseased genes. The reason is partly to blame on the ignorance of society, because it believes that genetic engineering is wrong. The part of genetic engineering that is wrong is holding back the natural process of science evolution. Some benefits are used in medicine today, but the real benefits will come as genes can be altered more. The real benefit that will help mankind is when bioengineers will be able to replace a cancer or defective gene with a gene that does not have an error in its genetic code. "The new science of genetic engineering aims to take a dramatic shortcut in the slow process of evolution" (Stableford 25). What is meant by the previous quote is that scientists hope to take a gene from an organism and change it so that it will be immune to certain diseases and free from cancer. For example, many years ago small pox was widely spread. Today it is almost nonexistent, because of the evolution of man. The only problem with this was it took hundreds of years for our genetic code to adapt and make our bodies fight it. The moral question of genetic engineering is answered by looking at the advances in medicine. Today the advancements in medicine are evolving at an extremely high rate. If the science of genetic engineering is wrong, then so are the rest of the advances in medicine. The reason is because genetic engineering is just another form of medical advancement. Gene manipulation is not going to be used for any
