Discussion about Genetically Modified Foods
a. The genetically modified foods are a long issue which is widely debated. b. People feel confused about their safety.
a.) Magana-Gomez’s argument.
b.) He argues that negative effects of GM food were identified “at molecular and microscopic levels”. c.) Curieux-Belfond CL contends that the benefits of genetically modified foods far outweigh the disadvantages. II. Genetically modified foods: Beneficial views & Adverse views a. What is the possible risk for genetically modified crops considering nutrition and health? b. Whether the economic effects are the most important?
c. Will it bring severe environment problems?
III. Arguments for beneficial effects of GM foods
a. Firstly, transgenic technology has made considerable progress in food applications. b. Transgenic food has successfully lowered food prices and ensured food safety. c. GM foods significantly reduce the environmental impact of agriculture.
The author, Magana-Gomez, critically analyzed the risk assessment methods of transgenic food for human nutrition and health in the paper, “Risk assessment of genetically modified crops for nutrition and health”. Magana reviewed various modes including different feeding period, animal modes and parameters in the paper published in 2011 by Nutrition Reviews (Magana G, 2009). In consistent with his studies, negative effects of GM food were identified “at molecular and microscopic levels”. However, with our entry into the 21st century, genetically modified foods have undergone even faster development. However, there are also many doubts about the safety of genetically modified foods. Therefore, genetically modified foods have become a hot topic issue. Personally, although there are many controversies about GM food, I still insist on the research and promotion of transgenic food due to its diverse benefits. Views
According to Curieux-Belfond CL, he could identify the factors that deserve consideration before “commercialization and promotion of transgenic food” (182). In this paper, “Factors to condider before production and commercialization of aquatic genetically modified 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 & Policy suggested that GM food undoubtedly contributed to economic benefits without exerting too much extra burden (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
Magana’s argument is persuasive when he assessed the risks about GM food. However, since genetic engineering techniques have successfully transferred anti-viral, insect resistance, cold resistance and other genes to cotton, wheat, tomatoes and other plants, we can get stable new varieties of genetically modified, with low production cost and high-yield food, which will ease the world food shortage and reduce the use of pesticides to a large extent. Based on the above reasons, I will provide a critical analysis with the following specific 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 muscle protein content and improve growth speed. With the development of genetic engineering technology, people have been freed from natural enzymes to a large extent. Especially when the enzyme obtained from natural protein material encounters difficulties,...
