AbstractAfter the birth of cloned sheep, Dolly, much more people have started to be interested in cloning technology. Many types of researches are done by scientists, and the technology is progressing every day.
Surely there are benefits of researching cloning, for example, clone technology has possibilities that it would be applied to cure diseases. However, it also has negative aspects. There is the company which sells cloned cat as a business. Moreover, researching human is becoming more popular. These facts would cause difficult problems like social and ethical problems.
Therefore, it is important to limit cloning and to ban human cloning. Although cloning is useful technology, at the same time, it is very dangerous. We must think about it carefully.
Cloning -All Types of Cloning Should Be Limited-In March, 2004, a surprising article was published in the U.S. journal Science. South Korean researcher, Hwang Yoon-Young, succeeded in creating human embryos through cloning and extracted embryonic stem cells. It was such a big achievement because it was the first time to successfully create an embryonic stem cell from human beings, so people all over the world paid attention to the article. Before that time, there had been some successful attempts to make stem cells from mammals like sheep (Dolly) and cattle, but no one had been able to create stem cells by cloning from primates. Researchers could not do the same thing, even from monkeys. Moreover, in May 2005, his research team claimed that they had created 11 human embryonic stem cells using 185 eggs. It is thought that stem cell technology has the potential to cure many crippling illnesses, such as diabetes, spinal cord injuries and Parkinson's disease; and the achievement of Hwang meant that it is possible to provide custom-made treatment to every patient without immune reactions. Therefore, people thought that it was great achievement and some people even said that Hwang would win the Nobel Prize. However, it turned out that both Hwang’s articles were fakes, and in January, 2006, the journal Science announced that they had eliminated these articles officially. (BBC, 2002).
Today, cloning is becoming a more acceptable idea and many people have started to be interested in it. However, it would be difficult to say exactly what cloning is. We can define clone as “the name for a group of organisms or other living matter with exactly the same genetic material. Genetic material consists of genes, the parts of cells that determine characteristics in living things” (Burbelo, 2006). Therefore, identical twins or other genetically identical multiple births are examples of natural clones. The history of cloning is longer than one would expect. Since the mid 1900’s, scientists had already started to develop their tentative technique for cloning higher animals. This type of cloning is called reproductive cloning. According to Human Genome Project Information, “reproductive cloning is a technology used to generate an animal that has the same nuclear DNA as another currently or previously existing animal” (2006, para7). At the same time, there are other types of cloning: DNA cloning and Therapeutic cloning. DNA cloning means a process that is “the transfer of a DNA fragment of interest from one organism to self-replicating genetic element such as a bacterial plasmid,” and “therapeutic cloning is the production of human embryos for use in research” (2006, para7,para3). Cloning technology contains different types, and it has both merits and demerits. However, it seems more important for me to consider the risks which will be brought by demerits such as designed babies and the threat against people’s sense of individuality than to think about expectations for merits like development of medicines. Therefore, it is essential to restrict cloning researches.
Mainly, there are two merits for cloning. One is the fact that cloning technology can apply to research projects on diseases. The other is that we will be able to repopulate endangered animals. As mentioned above, cloning has huge potential for human medical care. More specifically, the process of therapeutic cloning can be used to study human development and to treat disease. Because “stem cells can be used to serve as replacement cells” (Human Genome Project Information, 2006, para10), it is possible to treat heart disease, Alzheimer’s, cancer, and other diseases. If these technologies are developed, for instance, organ recipients would do not have to wait for organ donors for a long time, and also they would not need to worry about organ rejection. In addition, in the future, we may be able to use this technology not only for protecting animals from extinction but also for producing live stock like pigs and cattle which are high quality. It means that this technology would bring human beings sustainable food supplies. (Bren, 2003).
Perhaps, Dolly is the most famous example of reproductive cloning in the world. In 1996, a group led by Ian Wilmut, the British scientist, succeeded in producing a cloned sheep. When the birth was announced in 1997, it became a scientific sensation. Dolly died in 2003. Generally, sheep live 11~12 years. Although there's no proof that cloning was to blame, her relatively early death caused a debate about the ethics of cloning research and the long-term health of cloning.
Genetic Savings and Clone, (GSC), which was a company established in 2000, had started a business which was to sell cloned animals. This fact also caused big debates. GSC insisted that their goal was to help bereft pet owners by copying their aging and diseased cats and dogs. Some people, however, criticized it as Frankenpets. GSC has recently closed, but it did sell a cloned cat to one of its customers. (Genetic Savings and Clone, 2006)
As one can see from these facts, cloning technology is developing rapidly and the effects to our life are becoming greater. At the same time, some problems have occurred. First of all, there is a technical problem. The probability that cloning animals succeeds is very low, besides, mammal cloning techniques are not perfect, and scientists have also found it difficult to produce healthy clones consistently. For example, the process failed 276 times to produce Dolly. (Love, 1997). Furthermore Dolly lived only 6years. It is not clear whether there is any connection between the death and cloning, but some people say that there was something wrong in its telomeres. They said that Dolly’s telomeres were shorter than ordinal sheep’s one. Telomeres are used as we get old. “Aging is thought to be due to shortening of telomeres, regions at the tips of chromosomes which prevent genetic threads fraying every time cell divides. Over time telomeres get worn down until cell-division is no longer possible” (Cloning, 2006, para14). In short, creatures’ lifetimes are determined by the length of telomeres.
However, the most difficult and biggest problems are ethical problems. There are many arguments about cloning, especially human cloning. A survey shows us that about 60 percent of Americans are opposed to human cloning. Though human cloning sounds like science fiction fantasies, the experiments have already started. In 2002, November 27, BBC reported that “the controversial Italian doctor Severino Antinori has announced that the first human baby clone will be born in January 2003” (“Human clone” unlikely say experts, 2002). On the same day; BBC also reported that “an organization called Clonaid claimed it had five women pregnant with baby clones. It said a baby girl would be born in December.”(“Human clone” unlikely say experts, 2002). Actually, Dr Severino did not hand in the proof of this pregnancy, so it was very doubtful whether he truly succeeded in creating human clone. However, human cloning is being realized step by step. The question is if human cloning is possible technically, is it good thing to create human clone?
Though the people who are for human cloning insist that it is very likely that cloning technology is prevented from developing by the argument about ethical problems, but the impacts which will be brought by the ethical problems in the future are bigger than the influences which will be made by the development of the technology. Therefore, it is key point to think about ethical problems seriously. One of the potential examples which will occur because of human cloning is a designed human. In a word, scientists would try to create “perfect” children. The people who are against human cloning say “the whole cloning process will lead to even more disrespect for life, and will further lead to the commodification of life- treating human beings as machines”. (Diggins, 1993, p181). Furthermore, they continue, “people’s sense of individuality- an important part of who we are as human beings- could be in serious jeopardy”. (Diggins, 1993, p 181). On the other hand, some people say that “it was the parents’ right to decide what to do with their embryos…with a presumption of privacy and liberty, that people should be able to live their lives the way they want and to make babies the way they want”. (Diggins, 1993, p 182). They also say “its novelty will not prevent parents from loving and acting in the best interests of children born in this way”. (Robertson, 1993, p193). Surely, it might be parent’ right, but how about baby’s right? It is clear that it is not problem only for parents but also for babies. Because the possibilities that cloned babies have some disabilities and diseases will be higher than normal children. Moreover, there is no guarantee that they will not be discriminated by others in the future.
Based on my research, all types of cloning should be limited by government regulation, and human cloning should be banned. Some laws have already been passed and applied in some countries, and there is the social trend which tries to make restrictions against cloning researches. For example, in Japan, the law which bans human cloning was created in 2001. Australia also bans human cloning, but therapeutic cloning is legal. On the other hand, in America, there are no federal restrictions for cloning. “Congress failed to pass legislation in the 1997-98 session. In 2001 the House of Representatives passed a bill to ban both reproductive and research cloning, which President Bush indicated he would sign.” (Center for Genetics and Society, 2004). Although the bill was passed by the House of Representatives, “in 2002, the legislation was tabled and a vote was never taken”. (Center for Genetics and Society, 2004). However, some American stets have banned cloning.
Certainly, the possibilities of cloning technology are great, and it is good thing to research it for the sake developing of medical care. However, the most important thing is not to hurry to do anything. The developing speed of clone technology is too fast, and the social conditions surrounding cloning have not been established. Because cloning is so difficult and sensitive problem it is natural to take much time to consider it. The best way is to set up detailed laws about cloning before researchers proceed further.
