Transcript of GENETIC MODIFIED ORGANISMS

GENETIC MODIFIED ORGANISMS Health Risks Environmental hazards What do people say about these kind of food? What is it? Food that is produced by using the latest molecular biology techniques, and it consists in modifying the genes of one organimsm and putting them into another, altering the genetic structure. These foods have been sold into the market for more than 10 years. Now, there is a prevalence of 60 % of food and agriculture products sold into the market. Our health is in risk since there arent many studies that show the effects on genetic modified organisms on human health.

A studied done by Arpad Pusztai examined the effects of GM potatoes on the digestive tract in rats. The results showed considerable differences in the intestines of rats fed with genetic modified potatoes and rats fed with unmodified potatoes. Genetic modified organisms can affect the mucosa of the gastrointestinal tract and develop secondary effects. Biotechnology scientists isolated a virus that demostrated a tremendous capacity for promoting transgenic between species. This was the Cauliflower mosaic virus CaMV 35S that scientists asumed it would be denatured in the digestive system. Engineering bovine growth hormone is another risk for our organisms since it comes from treated cows that are fed with antibiotics, more growth hormone, and more IGF-1 which is a hormone linked to cancer. Researches in Austria and Italy said that genetic modified food has been linked to toxicity and allergic reacrtions not only in hiumans, but also in animals. The environment is also being harmed by this way to produce food In 2002, a studied demostrated that butterflies are being affected by the produce of corn in which its polen is producing a big mortality rate on monarch butterflies. Crop plants that has altered genes can crosspollinate with other plant crops that are not being tested. Biopharma corporationas are very worried because this crops with unnapproved genes can contaminate other food crops not only by wind but also by insect pollination. Nina Fedoroff, a member of the National Academy of Science says "If we put more land under cultivation to feed the world's growing population, we're going to pull down the remaining forest", and that "there will be an increase in desertification and damaging the forest" There were different circunstances in the past related to GMO foods.

- Hamilton County
An crop area that had plants from seed corns genetically modified to produce proteins that contained drugs for treatment of diarrhea in pigs.

- GE StartLink corn
7 years ago, this corn had been approved for animals. These soybeans were also consumed by humans!!! It resulted to be in taco shells, chips, and other processed foods!!! What do Scientists say about GMO's? The United States Departement of Agrivulture has approved the grow of biopharma crops pon corn, soybeans, barley, rice and tobacco in the United States. These plants contain medicinal substances like insulin, anticoagulants and blood substitutes. They also produce vacine proteins for diseases like cholera and antibodies for tooth decay. Therefore, Biotechs says "the benefits outweigh the risks, and that the risks are managable" Scientists say that modified food have the potential to solve many of the world's hunger and malnutrition problems, and to help protect the environment by increasiong yield and reducing reliance upon chemical pesticides and herbicides. Nina Fedorrof says "there is almost no food that isnt genetically modified and that genetic modification is the basis of all evolution." EXample: a Soybean which had proteins that improved allergic reactions in people.. In 2005, another studied of est resistant pea developed by the Australian CSIRO for use as a pasture crop was shown to cause allergic lung damage in mice Labeling Issues The Food and Drug Administration's 1992 GMO policy says "The agengy is not aware of any information showing that foods derived by these new methods differ from other foods in any meaningful or unifrom way". However, studies have shown the effects on human heslth. As a result, the growth hormone; for example, is banned in Canada, Japan, Australia, New Zeland, UNited Kingdom, but the United States. Monsanto, the number one producer of the rBGH synthetic steroid, has tried to avoid the label of its products. The company asked Dennis Wolff, the Pennsylvania Secretary of Agriculture, not to declare "free rbGH" labels in his state. Michael Taylor approved Monsanto's engineering bovine growth not to have label in the US when he was in charge of the FOOD AND drug Administration.
