Layla Katiraee Genetic Literacy Project November 13, Activists often cite the alleged potential health risks of genetically modified foods. Are these concerns credible? What do the studies cited actually claim? The authors identified the Bt protein Cry1Ab in maternal and fetal blood, a protein found in some GMOs, but also commonly used as a pesticide in organic farming.
What is the possible risk for genetically modified crops considering nutrition and health? Whether the economic effects are the most important? Will it bring severe environment problems? Arguments for beneficial effects of GM foods a. Firstly, transgenic technology has made considerable progress in food applications.
Transgenic food has successfully lowered food prices and ensured food safety. GM foods significantly reduce the environmental impact of agriculture.
Magana reviewed various modes including different feeding period, animal modes and parameters in the paper published in by Nutrition Reviews Magana G, 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.
In the end, the author believed that the benefits of genetically modified foods far outweigh the disadvantages. 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, genetic engineering has the unique advantages of natural gene cloning Seralini GE, Thus, it can be highly expressed 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 nutritional quality modified by genetic engineering has also made remarkable achievements.
For instance, the genetic engineering technology has been applied 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 helps increase production and food supply while reducing the farm labor and pesticide applications, agricultural inputs and production costs Weasel LH, In the future, GM crops have great potential in solving the food crisis.
For instance, by applying transgenic technology 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. Furthermore, GM foods have also proved effective in alleviating poverty and hunger.
So far, genetically modified cotton in India, China and South Africa have already made a significant contribution to more than 1.
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 million poor families in Asia, whose benefits will reach 10 million people Curieux-Belfond O, Transgenic food also helps to reduce land development.
Transgenic technology has been developed to improve the current 1. 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 biotechnology can help reduce this impact.
In the first decade of application of genetically modified crops, by planting herbicide and insect-resistant characteristics, transgenic technologies have greatly reduced the use of pesticides, saved fossil fuels and reduced carbon 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 role in easing the crisis of population growth and global food shortage Artemis D, GM crops have also contributed to reduce carbon dioxide emissions in two main ways, reducing greenhouse gas emissions and helping slow climate change.
First, by reducing fuel use, the spraying of insecticides and herbicides, GM crops continue to reduce carbon dioxide emissions.
Ingenetic engineering has been stated to reduce 1. Secondly, herbicide-resistant GM crops help reduce tillage applications, which protects the land and enhances soil 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 may cause harm to human health.
Moreover, after a large number of transgenic crops come into nature, they may be biologically harmful to ecosystems.The Effect of Genetically Modified Organisms In , Gregor Mendel published Experiments in Plant Hybridization becoming the first report of Genetically Modified Organisms.
What started as selective breeding eventually developed into one of the most prevalent technological advancements of today. A GMO (genetically modified organism) is the result of a laboratory process where genes from the DNA of one species are extracted and artificially forced into the genes of an unrelated plant or animal.
The foreign genes may come from bacteria, viruses, insects, animals or even humans. As an effect, genetically modified (GM) foods originate from genetically modified organisms. Such changes that lead to modification are much more precise as compared to mutation breeding.
GM foods were introduced in that market in early s, where such foods were typically plants, however, in , animal products were also modified.
Genetically modified organism: Genetically modified organism, organism whose genome has been engineered in the laboratory in order to favor the expression of desired physiological traits or the production of desired biological products.
Learn more about the development and uses of genetically modified organisms in this article. The Genetically Modified Organisms (Control of Release) Expert Group (Expert Group) in its first meeting held on 5 July discussed the risk assessment and disposal of GM papayas in Hong Kong.
Risks and Benefits of GMOs ; They also lay out the conflict over–well, even in naming the subject, we risk prejudicing the discussion.
Are we talking about genetically modified or even Frankenfoods (as in Frankenstein); or are we talking about a new Green Revolution? when you call the product a genetically modified organism instead of.
