美国作业代写：Ethical problems of human cloning technology

下面为大家整理一篇优秀的essay代写范文- Ethical problems of human cloning technology，供大家参考学习，这篇论文讨论了克隆人技术的伦理问题。克隆技术的快速发展，不仅带来了医学上的好处，也带来诸多社会、伦理问题。克隆技术分为治疗性克隆和生殖性克隆，其中生殖性克隆即为我们常说的克隆人。克隆技术带来的伦理问题，已经不仅仅局限于科学技术层面，更重要的是以克隆技术为借鉴，深入的探讨科学技术的伦理问题。

The rapid development of cloning technology not only brings medical benefits, but also brings many social and ethical problems. This paper discusses the ethical controversy of human cloning technology, the author puts forward the viewpoint on how to treat the technical ethics of human cloning, namely: rational view of modern technology, prohibition of reproductive cloning technology, promotion of the research and production of human beneficial cloning organs, so that it in the whole social system escort to the direction of human development.

Cloning is a group or group of cells or groups produced by a cell or an individual that repeats or reproduces in asexual form, having exactly the same genetic structure without mutation. Cloning technology is divided into therapeutic cloning and reproductive cloning, of which reproductive cloning is often said to be cloned human. In the February 1997, British scientists cloned the first cloned sheep "Dolly", the Dolly used the "Somatic cell nuclear transfer" technology, it is the first in the world without a sperm, egg binding, and the artificial embryo into the sheep's womb directly developed into the individual animals. The birth of Dolly sheep in the world has erupted in a "clone" of the ethical theme of the core of life science ethics controversy. Therefore, based on the previous research, this paper probes into the ethic of human cloning technology, in order to make some contribution to the promotion of technical undertakings.

In fact, the cloning of human technology is not only a scientific or technical problem, but also an ethical issue, which attracts many researchers to support and oppose the point of view. The birth of Dolly Lamb sparked a world ethic struggle. In favor of human cloning technology research, people believe that cloning human technology will be able to bring good development, beneficial to human progress, on the one hand, cloning technology can make people seriously consider the human genome improved optimization. People can make purposeful choices in the gene pool, use and combine the dominant genes, and sift and cull the disadvantage genes. Cloning, on the other hand, can change some of the genes in the human genome that have serious defects and prevent the next generation of genetic diseases. Cloning human technology can be used to treat diseases, can use embryonic stem cells to clone human organs for treatment of diseases, and can solve the problem of inadequate organ transplant donors, in short, it is potentially invaluable medical value. However, most people are opposed to the cloning of human technology, even caused by the world's panic. Most scholars and scientists have taken a resolute attitude of resistance, summed up, mainly due to technical risks, after all, the cloning of human technology is not mature, and there is a certain risk of technology, although people are animals, but obviously higher than the sheep, the gene sequence is more complex than other animals, so the clone of the probability of success is much lower than the cloned sheep.

The ethical problems brought by cloning technology are not only limited to the science and technology, but also the research on the ethical problems of science and technology. From the core values, respect for life is the main principle, from the technical value point of view, science and technology should be used to understand and transform the nature of human tools, is to serve the well-being of mankind, its value should be here. First of all, respect for human life value is not the principle of injury, the human life is paramount, ethics should first respect every existence of life, the principle of not harm is the fundamental principle, but also a bottom line, in any case this line can not be exceeded. Secondly, in essence, science is the objective of nature that human beings have discovered and mastered, the nature of science is freedom, the development of science has no limit, but when scientific research focuses on the field of life sciences, and the research results may adversely affect human life itself, it must be emphasized that scientific freedom is limited and scientific freedom is conditional. Science is not a no-go area, the freedom of science is not unlimited, but when scientific research object becomes human subject itself or is closely related to the existence of human itself, science is no longer absolute freedom.

The development of modern biotechnology has aroused people's fear of technology, but we should look at this kind of panic rationally, in essence, the fears of the wrong people who use technology. Whether or not support for the cloning of human technology is sufficient, the cloning of human technology can be harmful to the natural, social, and human, but this is not a reason to prevent its emergence and development, as a baby is born to be able to commit a crime, but can not prevent the truth of their birth. The cloning of human technology will never stop, because people's understanding of the world is never-ending. Science and technology is a double-edged sword, we should take a dialectical and rational attitude towards the cloning of human technical disputes, the development of human society tells us, whether a technology is beneficial to human development, the key is how to view and adopt it. To promote scientific ethics is not to hinder the development of science and technology, but to minimize the harm caused by science and technology to mankind, to this end, we should prohibit reproductive cloning technology, promote the research and production of human cloning organs, the study of reproductive cloning should be based on social, ethical, policy, legal analysis, formulate corresponding policies and regulations, standardize the behavior of scientists. Support therapeutic cloning research to make it more beneficial to mankind. Finally, the emergence of human cloning technology is the inevitable result of the development of science and technology, in that case, we should not blindly prohibit and oppose the cloning of human technology, but should make it in the whole social system of the escort to the direction of the human development, better benefit to mankind.
