基因工程的优缺点英语作文Human gene field has made great progress, and through genetic engineering in order to offer service to change the nature of need progression. But, in a very long period of time, to the philosophy of human genetic engineering ethics problems enough attention. Cloning technology to the human genome from since the great discovery, a growing problem, and compared with this process, human corresponding social ethics system is not established.Genetic ethics is its contents include the look, but there are two aspects; one is ecological ethics, on the one hand, is the social ethics. Would gene for ecological ethics, mainly to regulate and coordination of genetic engineering and the contradiction between the ecological environment; Just as the social ethics, gene is mainly to regulate and coordinate gene engineering and social or ethical problem. The establishment and development of genetic ethics not only won't hinder development of natural science, it will further enhance our understanding of the nature of science, will also help us to the truth, laws, causality new understanding.Ecological ethics for plant genetic research work of norms and reasonable constraint, mostly for biodiversity consideration. In recent years, the plant gene research made rapid progress, these advances drive a series of the agricultural revolution, and especially in food revolutionoriented. However, this to plant gene optimization based revolution, has led to the destruction of the species diversity. For example, it makes people eat food from 5000 kinds of shrunk to 150. A similar is for increasing production and shorten, fertilizer played a pivotal role in growth, but also caused the soil harden and surface damage. The same situation also happens in the research and application of animal genes. For example, tube cows and sheep for people to control tube biological gender provides the basis for this technology for possible human biological of population control. On a particular populations, male quantity don't need a lot of, but the female, according to quantity is important laws of nature, the male female born roughly, therefore, the probability of how to increase in female born quantity and reduce the number of male is critical. But this way, would cause the imbalance of female proportion, causing the natural ecological unbalance. When this technology applied to humans, a bigger problem. Some time ago on cloning technology discussion shows that the gene cloning technology once used to humans, may bring or cause trouble not even we can imagine.So, whether genetic ethics genetic engineering and gene technology conflict? Obviously not, because genetic ethics and genetic technology to serve man this is essentially identical. Both requirements should make full use of gene technology for the benefit of mankind, and to generateas much as possible to avoid interfering all harmful to society phenomenon. Just different countries and regions, the degree to which and the proportion between the difference. For developing countries like China, it is not how focused try to overcome the genetic engineering of gene technology, the negative influence, but how to best possible use genetic engineering and gene technology economic development. For example, we all now know that biodiversity is the base for sustainable development of nature, i.e., evolution is not to "balance the disadvantages of mutual coordination, but, is a diversified process, and the optimization is inevitable to monotonicity. However, at present, genetic engineering major is among the best, obvious optimal with biological diversity direction in practice, and ran contrary indeed caused also this problem. But, to the vast number of developing countries, so it has solved many very difficult realistic problem.It can be learned, the establishment and development of genetic ethics not only won't block development of natural science, it will further enhance our understanding of the nature of science, will also help us to the truth, laws, causality new understanding. Obviously, genetic engineering is undoubtedly conform to the laws of nature. However, the result will to nature social sustainable development put forward tough challenges, this chapter for truth and by people scientific issues of depth. This question is actually a junction with something culture substantialcontents of the problem. Several Nobel Prize for physics in the physicists about Chinese traditional culture and western culture have said, the western natural science about "laws" concept and in the China traditional culture "reason" is "the same thing". In fact, if only from the phenomenon seems to yes, however, said mediocrity are very different up. Natural scientific law concept, mainly reflects the nature of the properties, and self development in Chinese traditional culture, the major reason of concept, it is a kind of sustainable development of social order. There is a common side, this is about Chinese traditional culture syncretic thoughts, in this case, the society also can be regarded as part of the nature of generalized and follow nature. However, two also have many differences. On the one hand, nature does not in itself will guide balanced, stable, orderly and sustainable development, as natural disasters is also performed about the same as the laws of nature, nature have not produced in before they eliminated many species. Cannot simply think that only man-made not abide by the laws of nature behavior will lead to sustainable development problems, and destruction that nature.。

Benefits of Genetic Engineering to the Environment and Human Health覃靓(澳大利亚卧龙岗大学,澳大利亚卧龙岗)Abstract: The purpose of this essay is to argue that the genetic engineering may bring about benefits to human health and the environment.By means of research of secondary source collection, relevant evidence is selected, evaluated and organized into three main parts: improving agricultural environment, providing effective medical therapy and supplying safe and nutrition food to human body. In order to explain the benefits that created by genetic engineering technologies, examples based on opinions of experts and results of experts' experiments are used. The research results strongly suggest that the genetic engineering has positive effects on environment and mankind. Base on those finds, the argument is justified that genetic engineering is certainly beneficial to the environment and human health. In the future, more attention and researches should be focus on the genetic engineering with the purpose of benefiting human beings and the natural worlds.Key words: genetic engineering; benefits; human health; environmentOverseas English2011年4月Along with the extremely serious environmental problems worldwide and more public attention on human health, it has become increasingly significant to achieve a harmonious balance between environment and scientific development. Similarly, pursuit of a coordinated(协调的) coexistence(共处) of the genetic engineering and environment is a prerequisite(先决条件) for the development of this technology. Genetic engineering is one of the eco -technologies in the21st century. Many countries exploit this technology to improve the agricultural productivity and prolong(延长) human life span(寿命). The existing significance of genetic engineering lies in its benefits to human being and natural world. The term genetic engineering can be interpreted as(看作) a high technology used to create new types of plants, animals or organisms（生物体）by changing the gene structures in order to fulfill specific purposes. Genetic engineering has positive effects on the environment and mankind. It can be argued by analyzing three areas about the good effect of genetic engineering on environment and human health, including improving environment, providing effective medical therapy and supplying higher nutritious and safer food to human body.Genetic engineering possesses a favourable influence on the environment. Many countries rely on genetic engineering to solve the problems of food shortage and realize the high yield of crops. Thereupon, genetic engineering has been widely applied to agriculture and generated several agricultural environmental benefits. Transgenic crops reduce the wide use of insecticides and eventually protect the environment. According to a recent study (Snow . A et al., 2005, p380), transgenic crops can fight back lepidopteran or coleopteran vermin and prevent common diseases from spreading owing to its natural ability. Their findings demonstrate that transgenic crops own pest control effect itself, thereby they resist the pests and ward off several diseases without any environmental pollution. Meanwhile it relieves overuse of insecticides and fungicides in favour of agricultural environment. This research implies that transgenic crops are of great environmental - friendly values in controlling pests and reducing agricultural pollution. In addition, genetic engineering realizes (achieves) a widerange of greening, in this way, genetic engineering substantially benefit the environment. According to Hisano, H, "With the availability of information of genes involved in ligin biosynthesis and by taking advantage of development in plant transformation technology, it is now possible to modify or reduce ligin content in biofuel crops" ( 2009,p307). The sedimentation of ligin impedes the growth of plants; however genetic engineering technology help cut down the ligin components and protect the landscaping. From this study it is not difficult to find that genetic engineering is of significant environmental benefits in maintaining wide scope of greening. Finally, genetic engineering is frequently used in the industrial fields to reduce industrial pollution and to improve the environment. For instance, genetic engineering technology supports sanitary biofuel production which is a suitable replacement for energy source. A type of biofuel called ethanol, for it is derived from plants, with a minimal level of toxins, is liable to biological degradation and creates less air pollution than ordinary fossil fuel. This biofuel can also decrease the greenhouse gas emission. (Sticklen,2008,p433). Conclusion draw from this research is that genetic engineering protects the environment by providing alternative clean resources. Therefore, it can be confirmed that genetic engineering indeed plays a positive role in the environment instead of having negative effects. Genetic engineering provides human being with an effective medical diagnosis, prognosis and therapy. Genetic engineering can be reckoned as an optimal technique in medical field and supply signals to predict various types of specific diseases. Genetic engineering output has the great potential to predict sickness recurrence or therapy response, which demonstrates the considerable medical advantages of genetic engineering. Lara Dunn & Angela DeMichele found that gene expression profiling changes the expression into signals that prognosticate disease recurrence or therapy reaction (2009, p74). Patients respond distinctively different to specific therapies. Signatures derived from the gene expression profiling identify these individual differences. Based on these individual differences, doctors analyse each patient's condition and make the decision whether or not use specific treatments and which treatment should be adopted to effectively address the single patient's disease. Therefore, examining the response of each patient to specific therapies with gene expression profiling is significant for maintaining the security of patients and pursuing an optimal treatment. This study suggests that genetic engineering is conducive to humanhealth in predicting the sickness recurrence or treatment reaction of patients and instructing people's decision on treatment choice. Besides, genetic engineering has the possibility to predict metastatic potential of breast tumours. One example that has been carefully examined in studies is the genome-wide technology. In his study, Keltouma Driouch et al. states that "Genome-wide technology, with its ability simultaneously to interrogate all *25,000 human genes, provided a way to improve the prediction of the metastatic potential of breast tumours."(2007,p575). Their findings show that tremendousdifferences in gene expression reveal distinguished molecular portraits of breast cancers. As a result, gene expression prog- nosticates the metastatic breast tumours. From this research it can be found that genetic engineering benefits human health in predicting the metastatic breast cancer. Equally important, genetic engineering make immeasurable contributions to the fields of precautionary diseases. Larissa Lumi Watanabe Ishikawa1 et al. state that "DNA vaccines generated humoral and cell-mediated immune responses followed by protective efficacy in different experimental models of infectious diseases including tuberculosis" (2009, p2). Once DNA vaccines are injected into the human body, human bodies contain an intense immune ability and protective function. Human bodies have a strong resistance to several infectious diseases like tuberculosis. It is apparent to find out that genetic engineering is beneficial to human health by producing effective DNA vaccines. Thereby, genetic engineering obviously plays a useful role in aiding medical prognosis and therapy, with ultimately benefiting the human body.Genetic engineering is conducive to（有利于）human body by providing people with safe and high-nutrition food. Food is the essential part of human life. Improving the quality of life and enriching food nutrition are always the focus of the scientists. Since this point, genetic engineering is exploited to improve food. Intensive food researches conducted over the past two decades have proved that genetic engineering supplies high nutrition food to mankind by changing the original gene features. "Golden Rice" can be considered among the most outstanding. "Golden Rice” is devised to relieve scarcity of vitamin A and this program signifies genetic engineering technology' s prospect to resolve undernourishment problem especially in developing countries (Patrick, 2006, p114). This research testifies that genetic engineering can benefit human body by lightening the lack of vitamin A and increasing the food nourishment. In addition, transgenic cereals（谷类）with improved quality features enhance the health of consumers. Godwin claims that genetic engineering manufactures cereals with improved and new properties (2009, p383). Cereals are the staple food for most people all around the world. Cereals with enhanced attributes signify higher nutritive value of starch, protein, vitamin, and other nutritional components. By so doing, human beings take in more nutrition by consuming genetic cereals. This study also accounts for advantages of the genetic engineering on human bodies by providing food nutrition. Furthermore, genetic engineering makes food safer. Scientists take the recombinant DNA measures to add new features into crop plants. Some researchers endeavour in triturating a soybean species with specific gene elements. According to Ronald Bailey, this type of soybean can never cause reaction on people who are allergic to nuts (2001, p107). Similarly, genetic engineering can be used to remove allergens in some foods like vegetables and potatoes. From the research, genetic engineering provides safe food and benefits human body. On the basis of reasons above, genetic engineering is undoubtedly beneficial to human body by means of offering rich food nutrition and maintaining food safety. Judging from all evidence presented above, it is strongly believed that genetic engineering holds favourable impacts on the environment, makes a great contribution to the medical field and offers human beings safe and nutritious food. Therefore, genetic engineering creates enormous benefits to the environment and human being. In the future, additional resources and energy should be devoted into the researches of genetic engineering in various fields and allow genetic engineering to make further benefits to mankind.。
