¶ … Environmental Risk of GMO
The environmental risk of genetically-modified organisms (GMO) is a controversial topic that has been addressed in peer-reviewed journals by researchers, some of whom claim there is a high-risk to GMO (Seralini et al., 2012) and some of whom claim there is no discernible risk (Tien Huy, 2013). This paper will compare and contrast the two risk perceptions in two articles, identify the environmental stressors that are related to the environmental risk, and conclude with a discussion of my own risk perception of GMO.
The risk perception of GMO on the environment is high according to the study by Seralini et al. (2012), in which is shown that the results of a 2-year study of rats that were fed Roundup-tolerant genetically modified maize indicated a direct link between the GM corn and death: "In females, all treated groups died 2-3 times more than controls, and more rapidly" (Seralini et al., 2012, p. 4221). Male rats fed GM corn were 4 times more likely to develop "large palpable tumors than controls which occurred up to 600 days earlier" (Seralini et al., 2012, p. 4221). The study also found a link between a diet of genetically modified organisms and chronic kidney failure in both sexes of rats. It concluded by explaining the outcome: the Roundup-resistant corn severely disrupted the endocrine system. The rats also suffered from an "overexpression of the transgene in the GMO and its metabolic consequences" (Seralini et al., 2012, p. 4221). Seralini et al. thus argued that genetically modified foods posed a direct environmental health threat to consumers of such products. The scientists asserted that GMO poisoning could be likened to "environmental pollution" (p. 4222).
Seralini et al. clearly show that the environmental stressor in their study is the genetically-manipulated maize. However, in a follow-up analysis of the study,...
GMO stands for genetically modified organism. GMO foods are microorganisms or organisms with genetically altered material that contain a piece of DNA from another organism. Pieces of DNA that are stitched together are the work of modern recombinant DNA technology, and can be done regardless of the pieces' source. The technology has been around for decades. As early as the 1980's researchers have stitched pieces of DNA together to see

Sustainable Rules Drake Nash RLMT 307 Food and Beverage Reverse Logistics -- Fall 2015 Ayers The implementation of sustainable rules and regulations as well as constraints in the markets across the world, have compelled international industries, in this case, the food and beverage industry, to establish reverse logistics, which is the backflow management of the supply chain system. Reverse logistics encompasses the waste management of products and merchandises in the backward supply chain.
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
production of food products has changed dramatically over the past several years. Technological changes in machinery, increased use of better and more expedient forms of transportation, and improved fertilizers have all contributed to a more efficient food production process. This more efficient process, however, has not come with some requisite problems. The existing system of delivering food products in the United States is a major contributor to the world's global
For example, if birds feed on seeds and a certain variety of insect, without the seeds, the birds may disappear, and the insects would then overpopulate the area. In addition, the cost of GM crops is initially high to the farmer. These seeds cost much more to develop and test, and so, they are much more costly to the farmer. They might benefit Third World agriculture in many ways, but
