With the development of world population and economy ,and peoples pursuance to the quality and quantity of food ,all of which result in the advanced biotechnology applied in food development broadly,especially the transgenic technology applied in increasing food output and category.The transgenic technology not only solves the problem of food and clothing all over the world,but also enriches our food varieties.However,the transgenic technology is not easy to apply in food,which brings both pluses and minus .Meanwhile ,some hidden dangers exist in this technology .Therefore,it is an important issue for us to apply the transgenic technology appropriately in food production and benefiting mankind.
Every coin has its two sides, the advantage of genetically modified food is can bring convenience to our life, improve the level of our life. Toxicity and problems at present a lot of people to genetically modified foods, allergic reactions, nutritional problems, resistance to antibiotics, as well as such problems as environmental threats are questioning attitude,. In fact, to be fair, every new thing, have it than by a growth process. We should use objective criticism and inclusive vision to think of genetically modified foods have more advantages: can increase crop yield per unit area; Can reduce the production cost; So as to bring greater investment returns ratio; Through transgenic technology to improve crop yield, insect-resistant effect, only the first step in the development of transgenic technology, is also relatively easy to do. Scientists are now considering how to better use of soil to crops through transgenic technology of fertilizer, improve crops drought-resistant ability, make crops better use of water resources. Through transgenic technology can enhance the ability of crop pests, anti-virus, etc; To improve the water resistance of agricultural products, extend the freshness, meet the needs of people's living standard is increasing day by day; Can make the crop development time is greatly shortened; Can get rid of the season, the influence of the climate, the four seasons low-cost supply; Can continue cultivating new species, produce beneficial to human health food.
For now, however, genetically modified food, disadvantages as well. Some researchers believe that for artificial refining and added genes, can be achieved in some people want to achieve the effect of at the same time, also increase and accumulate the original traces of poison in the food; For a food allergy sometimes food allergic to a previously they do not produce allergic; Foreign genes could damage the nutrients in the food; Genetically modified species may also ecological environment destruction and pollution; Genetically modified foods may also cause new diseases. As for genetically modified food can't eat, of course, is currently one of the most controversial issues. In fact, can't eat, is to rely on time to test. Currently we should to do is stand in the professional point of view to analyze the pros and cons. To make the final judgment is the result of trade-offs. Genetically modified food is obvious can bring huge economic benefits to human beings, and can relieve the earth more and more of the most basic human dinner now. However, the same Because too much uncertainty also let people stay at a respectful distance from sb to it. Now, with the rapid development of the research and development and commercialization of gm engineering, potential danger to the safety of genetically modified (gm) food public doubts, in essence, genetically modified organisms and a variety of conventional breeding is the same, both are on the basis of the original by modifying certain traits, or add new traits, or eliminate the original negative traits. Conventional varieties bred only within or between relatives, and foreign genes in
transgenic plants can come from plants, animals and microbes. Although, current scientific level also can't accurately predict a foreign gene in the new genetic background will produce what kind of interaction, but in theory, genetically modified foods are safe. In addition, genetically modified foods listed many departments is through a lot of testing and strict inspection before; Because of the genetically modified food not accumulate in the body. As for wondering whether the genetically modified food may cause danger to the human body mainly is that they do not understand gm foods, and these \scientific basis. I believe in the near future of genetically modified food will make our life shine brilliantly.
