The discovery of genes has led us to a new understanding of the organism from a microscopic point of view. Based on the study of the relationship between genes and traits, scientists use genetically modified technology to modify DNA in organisms improving the quality and quantity of foods. In a world of rapid population growth and increased demands on living standards, genetically modified foods are gradually appearing in fields, on supermarket shelves and on our tables. However, different attitudes have emerged in terms of environmental contamination issues and allergic reactions among some people. Despite this, a large number of experts argue that genetically modified foods represent a significant advance because they contain high nutritional levels that can provide higher quality foods in the Western diet. Furthermore, the benefits of impressive yield can solve hunger problems in developing countries. Therefore, this essay will argue that genetically modified foods are beneficial for health benefits and economic interests. There is some merit to the argument that, due to negative impacts, genetically modified foods are unacceptable. One of the negative aspects is that GM crops can cause contamination to the environment. Transgenic plants through wind, insects, and other means will transport genetically modified genes to nearby wildlife, soil, and aquifers, with possible protective impacts such as damage to ecological balance (Snow cited in Ackerman, 2002). For example, 1999 research reported that Bt corn pollen transmitted Bt genes to the leaves of milkweed plants which killed monarch butterfly caterpillars and could disrupt the ecological balance by destroying species diversity in the long term (Ackerman 2002; Wohlers 2013). Additionally, some environmental concerns arise… half of the paper… allergic reactions may also occur. However, these barriers can be overcome with rigorous supervision and inspection by international organizations and governments. It is important to note that genetically modified foods have many advantages as they contain a high level of nutrition which can provide healthier foods. Furthermore, the benefits of genetically modified foods, characterized by rapid growth and high yield, can solve hunger problems in developing countries. Furthermore, literature shows that benefits from genetically modified foods, which have better adaptability in harsh environments, can reduce agricultural inputs, which can benefit the economy. Vaccines contained in genetically modified foods can reduce the minority by preventing vital diseases, which is a significant contribution. Therefore, to weigh the pros and cons, the application of genetically modified foods is acceptable because the urgent benefits it brings are more than concerns..
