Opener: What are genetically modified foods (GMF)?
Thesis statement: Genetically modified foods have both benefits as well as dangers to human health, the environment, and economy. Genetically modified foods have contributed to better foods in terms of food quality and human health. * higher nutritional value and better flavour
* increased shelf life
Genetically modified foods or organisms advocates enhanced farming techniques in terms of being environmentally friendly. * inbuilt resistance to pests, weeds, and disease
* more capable of surviving in poor soil or adverse climates Genetically modified foods are produced more economically thus has an impact on the global economy today. * more economical to farmers in terms of production and supply Some GM foods may potentially lead to new diseases and allergies affecting human * health.
* modified to be resistant to antibiotics
* may put consumers at risk for surprising allergic reactions Some concerns are that genetically modified foods may lead to environmental hazards. * gene transfer to non-targeted species can cause ecological problems * undesirable impact on biodiversity
Genetically modified food is young untested technology that can cause major economic problems if not handled well. * patent infringement costs involving genetic modification * end of food diversity
The Benefits and Dangers of Genetically Modified Foods
In the near future, kids may soon have the option to not eat their vegetables! The reason being, genetically modified foods have emerged from science labs quickly making their way to the dinner table. Firstly, what are genetically modified foods (GMFs)? Genetically modified (GM) foods are simply put foods that have had their DNA directly manipulated via genetic engineering also known as biotechnology. It uses recombinant DNA, where two or more genetic sequences are combined in a way that would not ordinarily happen in nature. Genetic engineers take DNA from a plant or animal and transfer it to crops through a range of techniques, which will ultimately give crops new or improved qualities. Genetic engineering, gene therapy, and cloning, are all possible because a scientist named James D. Watson paved the way for the molecular revolution in biology (Cullen, 2006, p. 144). Genetically modified organisms are used in biological and medical research, gene therapy and agriculture. The public is probably the most familiar with genetically modified organisms in the form of crops and foods (National Geographic, 2012). Some examples crops that have been genetically modified are maize(corn), rice, wheat, potato, soybean, tomatoes and cotton. Genetic engineering has been a topic of controversial debate for many years and will continue to be debated for years to come. It has been proven that genetically modified foods offer a variety of benefits. That being said, everything has a down side to it though we as consumers may not be aware of it. Hence, genetically modified foods have both benefits as well as dangers to human health, the environment, and economy Firstly, genetically modified foods are proven to have higher nutritional value and better flavor. They can also be manipulated to contain nutrients that help fight malnutrition. For example, blindness due to lack of Vitamin A is a common problem in third world countries. Whitman’s (2000) article states that researchers at the Swiss Federal Institute of Technology Institute for Plant Sciences have created a strain of "golden" rice containing high content of beta-carotene (vitamin A)13. Since Rockefeller Foundation14, a non-profit organization funded this rice; they hope to offer the golden rice seed free to any...
