Introduction The author, Magana-Gomez, critically crushd the risk discernment methods of transgenic food for gentlemans gentleman nutrition and health in the paper, Risk assessment of genetically circumscribed crops for nutrition and health.Magana reviewed various modes including different feeding period, sensual modes and parameters in the paper publish in 2011 by Nutrition inspections (Magana G, 2009). In consonant with his studies, negative effects of GM food were identified at molecular and microscopic levels. However, with our entry into the 21st century, genetically change foods fix undergone even faster learning. However, on that point are also many doubts about the safety of genetically modify foods. Therefore, genetically limited foods rent be do a hot topic issue. Personally, although there are many controversiesabout GM food, I still insist on the seek and set aheadion of transgenic food due to its various clears. Vi ews According to Curieux-Belfond CL, he could identify the factors that be consideration before commercialization and promotion of transgenic food (182). In this paper, Factors to condider before work and commercialization of aquatic genetically modify organisms the case of transgenic salmon, the author took transgenic salmon as an example, in which Curieux-Belfond examined the corresponding impacts in terms of aquaculture, wildlife, ecosystem and human health.The paper published in 2011 by Evironmental Science & form _or_ system of government suggested that GM food undoubtedly contributed to economic benefits without exerting too frequently extra core group (Curieux B, 2009). In the end, the author believed that the benefits of genetically modified foods far outweigh the disadvantages. Analysis of the benefits of genetically modified foods Maganas argument is glib when he assessed the risks about GM food.However, since genetic engineer techniques have successfully transf erred anti-viral, shucks lo handling resistance, cold resistance and other genes to cotton, wheat, tomatoes and other puts, we can get stable impudent varieties of genetically modified, with low production live and high-yield food, which allow ease the world food shortage and reduce the use of pesticides to a large extent. Based on the above reasons, I testament provide a critical analysis with the following proper(postnominal) examples which show his argument is partially wrong.Firstly, transgenic technology has also made considerable progress in animal food applications. At present, a variety of mammal and bird genes are successfully integrated into the genome of fish, which can significantly enhance transgenic fish muscular tissue protein content and break harvest-home speed. With the teaching of genetic technology technology, plurality have been freed from natural enzymes to a large extent. curiously when the enzyme obtained from natural protein material encounte rs difficulties, genetic engineering has the unique advantages of natural gene re-create (Seralini GE, 2011).Thus, it can be highly convey in microorganisms with mass production by fermentation. At present, the transgenic enzymes are widely used in the food industry, such as maltose enzymes amylase, pectinase and the juice protease. The food nutritionary quality modified by genetic engineering has also made rare achievements. For instance, the genetic engineering technology has been employ for seed protein improvement, which renders it possible to change the plant composition and amino acid content.Secondly, transgenic food has successfully lowered food prices and ensured food safety, which armed services increase production and food furnish period cut down the farm beat back and pesticide applications, countrified inputs and production costs (Weasel LH, 2009). In the future, GM crops have great probable in solving the food crisis. For instance, by applying transgenic t echnology to the human staple foods of rice and wheat, people can increase food production and improve nutritional quality, which will provide mankind with higher-quality food.Further more(prenominal), GM foods have also proved effective in alleviating poverty and hunger. The worlds shortest 50% of the population are small and resource-poor farmers, while 20% musical accompaniment in artless areas without their own footing actually suppose on agriculture. Therefore, the increase in diminished and resource-poor farmers income will directly assist 70% of the worlds poorest people (Curieux-Belfond O, 2009). So far, genetically modified cotton in India, China and South Africa have already made a significant division to more than 1. 2 million poor farmers income.The benefits of genetically modified corn in the Philippines and South Africa will be much clearer in the future. In addition, genetically modified rice has great potential to benefit 250 million poor families in Asia, who se benefits will reach 10 million people (Curieux-Belfond O, 2009). Transgenic food also helps to reduce state of matter discipline. Transgenic technology has been developed to improve the underway 1. 5 one million million million hectares of arable land productivity through conservation of biologic resources, thereby reducing land development and deforestation.Thirdly, I will demonstrate such improvement since they significantly reduce the environmental impact of agriculture. Traditional agriculture has a significant impact on the environment, and transgenic biotech can help reduce this impact. In the first decade of application of genetically modified crops, by planting weed killer and insect-resistant characteristics, transgenic technologies have greatly reduced the use of pesticides, saved fossil cans and reduced degree Celsius dioxide emissions.Undoubtedly, genetically modified crops with drought-tolerant genes will improve water-use efficiency and maintain sustainable agricultural development, which will play an important piece in easing the crisis of population growth and global food shortage (Artemis D, 2009). GM crops have also contributed to reduce carbon paper dioxide emissions in two main ways, reducing greenhouse gas emissions and helping remit climate change. First, by reducing fuel use, the spraying of insecticides and herbicides, GM crops continue to reduce carbon dioxide emissions. In 2007, genetic engineering has been stated to reduce 1.1 billion kilograms of carbon dioxide emissions, which is equivalent to a ebb of 50 million cars from the road. Secondly, herbicide-resistant GM crops help reduce tillage applications, which protects the land and enhances bemire carbon sequestration. Conclusions Despite the many advantages of GM food, we cannot ignore the risks. After genetically modified foods have been taken into the human body, they whitethorn cause harm to human health. Moreover, aft(prenominal) a large number of transgenic c rops come into nature, they may be biologically offensive to ecosystems.Since the risks of GM food is serous, it is important for us to polish on it first. Any of the scientific and technological developments should be comprehensive and provide well-being for human life. If genetically modified foods can only increase our economic interests and improved material life without the moral, kindly and environmental harmony, they cannot be defined as making great contribution to affectionate development. Therefore, whether GM food is a benefit or a disadvantage sincerely depends on what kind of human set people hold (Qaim M. 2009). That is the question we reflect on deeply.In contemporary society, with the fast development of science and technology, the economic internet site of the human and the material standard of life-time has been soaring. It seems that mankind is taking great soaring for the advanced technology. However, we should look back to what the living environment w e rely on is subjected to. Therefore, genetically modified foods are seen as the saviour of mankind, which is actually human self-centered ideology. Of course, with the straight development of biotechnology and genetic engineering, human beings have the ability to create more genetically modified food.Therefore, the drawbacks of genetically modified food are not the technology itself, but rather due to human race themselves. Thus, personally, I fully sanction the development of GM foods while we should objectively analyze the potential risks. Reference Artemis D. 2009. Health risks of genetically modified foods.
