Genetically Modified Foods
What are Genetically Modified Foods?
Genetically modified foods (GMF) are created through a biotechnological process known as genetic modification (GM). Genetic modification -- also known as genetic engineering -- alters the genetic makeup of plants, according to the Human Genome Project (HGP). Actually what scientists are doing when they genetically modify a plant is to combine certain genes from different plant species to basically change the DNA in the resulting plant species.
The HGP paper reports that in 2006, some 252 million acres of "transgenic crops" had been planted in twenty-two countries by 10.3 million farmers. These crops (corn, soybeans, cotton, alfalfa, rice, sweet potatoes and canola) were planted in order to reportedly resist insect infestation. The sweet potatoes were modified in order to "…resist…a virus that could decimate most of the African harvest" (HGP). Fifty-three percent of those crops were planted in the United States; 17% were planted in Argentina; 11% were planted in Brazil; 6% were planted in Canada and the remaining percentages were planted in India, China, Paraguay and South Africa (HGP).
Controversies -- Benefits
The HGP explains that the use of GM food is said to potentially increase food security for developing nations. Also, GM crops have "enhanced taste and quality," and they mature earlier than traditional crops (HGP). GM crops are said to have better resistance to "…disease, pests, and herbicides," the HGP site continues. On the negative side of genetically modified foods are the unknown long-term manifestations -- the "…potential human health impacts," and those include certain allergens and the "…transfer of antibiotic resistance markers"; moreover there is the "unintended transfer of transgenes through cross-pollination" (HGP).
Additionally the HGP notes that there is the potential for the production of the world's food by "…a few companies," which could lead to the "increasing dependence on industrialized nations by developing nations" and the possibility of "biopiracy" (foreign exploitation of natural resources) (HGP). There is also the ethical issue of simply "…tampering with nature by mixing genes" among several species and the fact that in many countries (including the U.S.) food manufacturing companies are not required to label the use of genetically modified ingredients on the food packages.
Deborah Whitman writes in the ProQuest publication CSA (Cambridge Scientific Abstracts) that genetically modified foods were created in part because the world now has more than 6 billion people and that number is expected to double over the next 50 years. An adequate food supply for those many billions of people is going to be necessary, and hence, GM food corporations have been busy planting millions of acres in GM crops, Whitman (2001) explains. Whitman notes these positives for GM food production: pest resistance; herbicide tolerance; disease resistance; cold tolerance; drought tolerance and high salt tolerance; nutritional value; the production of helpful pharmaceuticals (Whitman, 2001).
Criticisms of GM food production include: a) "unintended harm to other organisms" (for example, a study published in Nature reported that "pollen from B.t. corn caused high mortality rates in monarch butterfly caterpillars"; b) "reduced effectiveness of pesticides" (in the same way that mosquitoes eventually developed resistance to DDT, insects could become resistant to crops that have been genetically modified); and c) "Gene transfer to a non-target species" (the possibility exists that crops engineered to resist herbicides "will cross-breed" which could create "superweeds" that would be herbicide tolerant) (Whitman, p. 6).
In addition there are "unknown effects on human health" that could result from genetic engineering and modifying plants genetically could potentially open the door to the creation of new allergens, Whitman continues (7).
Corporate Ethics and Genetically Modified Foods
An article in the peer-reviewed Journal of Legal, Ethical and Regulatory Issues (Daboub, et al., 2012) reports that the "potential benefits" of genetically modified foods offer some hope for millions of "malnourished people" while at the same time genetically modified foods "…provide...
Genetically Engineered Food Over the last ten to fifteen years, the presence of genetically modified foods in grocery stores and homes has increased exponentially. This emergence of genetically modified foods has impacted many different details of human life, including in the areas of farming, research, fertility, the environment, and pharmaceuticals, just to name a few. However, there remains strong opposition to the use of this technology in foods that will be
Genetically Modified Organisms Technology GMO Gentically Modified Organisms A Genetically Modified Organism (GMO) is any organism that has had its genetic makeup altered by humans Ahmed, 2002. The organism could be an animal, plant, or microorganism. The changing of the genetic code could involve subtracting, adding, or altering. All these changes could be from the same species or different species, which would give the organism characteristics that it does not have normally. GMO
GMO Food The process of genetic modification of an organism Genetic modification of an organism is the process by which the genes of an organism are altered to introduce useful genes that are believed to help it to grow and thrive in any given condition. The genes contain DNA, a basic building block of all living organisms that is responsible for the presence or absence of certain traits or characteristics and modification
Protection and preservation of the environment through increased yields and reduced use of chemical pesticides and herbicides. This is because genetically modified foods grow at a faster rate and in bigger quantities which means less forest land is cleared for agriculture and the natural habitats and biodiversity is preserved. The crops are also made pest and disease resistant which means that less pesticides and herbicides are used which could pollute
On a biological level, consumption of genetically modified foods means the potential for "pleiotropic and insertional effects," Dona explains on page 165. Pleiotropic refers to the possibility that a gene may have more than one affect on the food. The above-mentioned effects could result from an increase of "anti-nutrients"; and moreover human health could be impacted due to the use of "viral DNA," Dona continues (165). The pleiotropic affect could
Genetically Modified Foods - Economics Genetically Modified Foods Genetically modified (GM) foods are changing how people in developed countries eat. There are also many economic questions surrounding them. According to Anderson (1998), society is moving toward a genetically modified world. The food the world eats, from meat to grains, fruits, and vegetables, is all going to eventually become GM food. This food can be made to be resistant to all kinds of
