A.It’s time to choose. Exposing the roots of genetically modified foods and the harmful effects it has on both humans and the environment. B.Genetically modified foods are harmful to both humans and the environment. C.Allergies, Bacteria and potential environmental impact Allergies D.Increase risk of allergic reactions with genetically modified foods than with traditionally bred food.
E.Inserting foreign genetic material into food DNA may create unknown toxins or allergens, he claims. In fact, Smith contends, soy allergies increased significantly after GM soy was introduced in the United Kingdom. Nevertheless, Smith asserts, GM foods remain unmonitored, creating risks for the millions of people who are eating them. Smith is author of Seeds of Deception: Exposing Industry and Government Lies About the Safety of the Genetically Engineered Foods You're Eating. F.My analysis and conclusion
G.The only human feeding study ever conducted showed that the gene inserted into soybeans spontaneously transferred out of food and into the DNA of gut bacteria. This has several serious implications. First, it means that the bacteria inside our intestines, newly equipped with this foreign gene, may create the novel protein inside of us. If it is allergenic or toxic, it may affect us for the long term, even if we give up eating GM soy. H.Research on this promoter suggests that it might unintentionally switch on other genes in the DNA allergens, toxins, carcinogens, or antinutrients. Scientists also theorize that the promoter might switch on dormant viruses embedded in the DNA or generate mutations. I.Analysis and conclusion
Potential environmental impact J.GM plants do not exist in nature their impact on natural ecosystems are uncertain.
K.“The proliferation of biogenetic plants also poses a concern. The pollen produced by these plants, carrying new genes, cannot be contained. As a result, genetic pollution of natural crop varieties and of wild plant relatives may occur. Genetic pollution may result from accidental or deliberate release of genetically engineered bacteria, insects, fish, and other life forms into the environment”.
L.There are many fears GM traits will spread to wild plants or harm wild life e.g. experiment on rats “In a study in the early 1990's rats were fed genetically modified (GM) tomatoes. Well actually, the rats refused to eat them. They were forcefed. Several of the rats developed stomach lesions and seven out of forty died within two weeks”. Conclusion
