Most foods in the United States have become genetically modified over the years, in fact, experts say that 60- 70% of processed foods on U.S. grocery store shelves have genetically modified(GM) ingredients. (Web MD, 2013) Due to the fact that the US is the leading producer in these genetically modified crops, there is a large amount of controversy surrounding whether or not these things are safe. Some of these concerns are that not many people really know what they are, why they have been modified, if it is safe to consume these products, and how they actually modify the ingredients to these foods. However, many people often assume things and make false arguments without doing research on the topic of genetically modified foods in the first place.
Genetically modified foods, according to the Food and Drug Administration, are foods with genetic material that has been altered in such a way that does not occur naturally. The government chooses to produce and sell these products because they have some specified benefit to them that differs from food to food. (WHO, int., 2014) The original idea of growing plants centered around genetically modified organisms was to appeal to farmers by improving crop protection. One form of this protection is insect resistance, which is done by giving a crop the gene for toxin production from the BT (Bacillus thuringiensis) bacterium. This bacteria is added because not only does it act as an insecticide, but it is also safe for human consumption. Seed developers also must add in certain bacterium to crops in order to make them tougher and more virus resistant. These additives can make plants stronger against diseases, producing higher crop yields. Lastly, herbicide tolerance is often added so that d...

...nherited normally, tests are run to check the amount of copies of the gene that have been inserted, if they are intact, and whether or not other genes are being unintentionally affected, and they also must test gene expression to check the functionality of the gene. In the greenhouse, developers then test whether or not the modified plant has the new trait and has not developed any undesirable characteristics, and if they pass they are then planted into the field for even more testing. They start out being planted in confined field trials to assure that the expressed gene works in the actual field, and if these tests are passed they move into multilocation environmental trials. If a GM crop can survive all of these tests then it is considered for commercial production. The safety tests take place during the time that the plant performance testing is taking place.
A GMO is a plant or animal that has been genetically engineered with DNA from bacteria, viruses, or other plants and animals. Most of the combinations which are used could not possibly occur in nature on its own. The intention of the process is to create a new beneficial trait such as creating its own pesticide or make it immune to herbicides. This would allow the crop such as Bt co...
GMOs are created by inserting DNA from bacteria, viruses or other plants and animals into a "target species" to create desirable traits. Most food today is modified to be resilient against pesticides and/or herbicides like Roundup. The first and only genetically modified food approved by the FDA for human consumption was the Flavr Savr tomato, which was slipped on grocery store shelves in 1994. Scientists at Calgene Inc. altered...
Genetic modification is a scientific way to enhance crops. The article “Genetically Modified Food” explains this by saying; “A genetically modified (GM) food is a result of recombinant DNA biotechnological procedures that allow the genetic Makeup of an organism to be modified. This can be accomplished by incorporating genes from other organisms of by rearranging genes already present” (Schneider 1). The genes used in the GM plants either comes from other plants of the plant itself. This means nothing going into the plant is from an unnatural source. “Statement by the AAAS Board of Directors On Labeling of Genetically Modified Foods” says, “Modern molecular genetics and the invention of large- scale DNA sequencing methods have fueled rapid advances in our knowledge of how genes work and what they do, permitting the development of new methods that allow the very precise addition of useful traits to crops…” (American Association 1). In traditional breeding there is a guess and check mentality w...
The past twenty years have seen rise to a new burgeoning scientific field: genetically modified foods. During the plant breeding process, geneticists interfere with the reproduction and modify the genes of the new seedling by introducing a fragment of DNA from another organism that possesses the desired trait. With genetic modification, scientists can increase the pest, herbicide, cold, and drought tolerance so that the crop can survive in harsher climates. In some cases, the nutritional value can even be increased (Ulrich 9). Despite the obvious benefits of more nutritious foods and crops that are hardier and more resistant to harsher climates, there are some concerns surrounding GM foods. Each new alteration can cause an unforeseen allergic reaction, negate the effects of antibiotics, or potentially cause some adverse effects to the environment (Falkner 101). Every newly developed GM food must be tested on a case by case basis as there is no universal method that determines the safety of all modified components. As a result, long term effects of ingesting food with altered material are unknown.
According to the Department of Agriculture, cotton, corn and soybeans are the most common GM crops in the U.S. In 2012, GM cotton accounted for 94 percent of all cotton planted, GM soybeans accounted for 93 percent of soybeans planted, and GM corn accounted for 88 percent of corn planted (add in text citation). This suggests that a large percentage of processed foods sold by supermarkets in the U.S. contain some ingredients derived from GM crops, primarily corn, soy, and canola. Yet, most Americans may not know that the products they consume contain genetically modified organisms (GMOs). Genetically Modified Food under Reasonable Government Regulation, is necessary for the continued and further success of the food supply chain.
From the Flavr Savr ™ tomato to the more recent genetically modified corn, genetic engineering has been around for about 20 years. Now, do you really know what GMOs (genetically modified organisms) are? Do you understand both the pros and the cons are? Are you positive that GMOs mat or may not affect your health or the enviroment? If you answered no to any of these questions I strongly suggest you continue reading.
Robert M. Hutchins, known for his contributions to philosophy, said that, “A civilization in which there is not a continuous controversy about important issues is on the way to totalitarianism and death.” While I do not necessarily agree with the former, or the latter, for that matter (no rhyme intended), it is imperative for us, as people, regardless of nationality, to ask questions. On the topic of important issues are genetically modified foods. The specific tangent on genetically modified foods is the question of whether or not genetically modified foods should have mandatory labeling. Instead of being a staunch absolutist and deciding so hastily on the matter of GMOs, the merits and drawbacks of this issue need to be discussed.
According to Approximately, 53% of the crops are engineered for herbicide tolerance, with another 33% for stacked traits, usually including herbicide tolerance. 14% are insect resistant using the Bt trait. Bacillus thurengiensis (Bt) is a spore forming bacterium that produces crystals protein, which are toxic to many species of insects. GM crops and their associated herbicides can harm birds, insects, amphibians, marine ecosystems, and soil organisms. They are reducing biodiversity, polluting water resources, and are making environments unsustainable for wildlife. A study published in Nature, one of the world’s leading scientific journals, has announced that Bt corn has contaminated indigenous varieties of corn tested in Oaxaca, Mexico. it was found that Bt corn destroyed the larvae of the monarch butterfly, raising well-grounded fears that many other natural plant and animal life may be impacted in the same way. It has been shown, however, that insects are fast developing resistance to Bt as well as to herbicides, resulting in even more massive infestation by the new superbugs. Despite GMOs crops being modified to be insect and herbicide resistant which increase our food supply nevertheless the modification done is harmful toward the
The term GM foods or GMO (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques (Whitman, 2000). These plants have been modified in the laboratory to offer desired traits such as increased resistance to herbicides or improved nutritional content. Also, genetic engineering techniques have been applied to create plants with the exact desired trait very rapidly and accurately. For example, this is done by the geneticist isolating the gene responsible for drought tolerance and inserts it into another plant. The new genetically-modified plant will now have gained drought tolerance as well.
The history of biotechnology and genetically modified (GM) foods has a history of opposing sides. The two opposing sides argue on the ethical standpoint of the act of genetically modifying plants and animals. They also argue on the health problems that the foods may cause for people that eat it. Going towards the future, people question whether GM foods have a positive or negative effect on humans. GM foods cause many assorted viewpoints consisting of positive and negative effects based off of its recent history.
“Genetically modified foods are a "Pandora's box" of known and unknown risks to humans and the environment. They have been forced onto the American public by multinational biotech and agribusiness corporations without adequate oversight and regulation by the United States government (Driscoll, SallyMorley, David C).”Genetically Modified Food is food which has been chemically altered by scientists during the production process to give the food more nutrients, better appearance, and a longer shelf-life (Rich, Alex K.Warhol, Tom). The importance of this issue is that these GMO’s can actually have a negative effect in our society in general. It could mutate in a negative way and cause cancer or other diseases. Genetically modified food should be strictly controlled due to its various detrimental effects on the environment, human health, and potentially insect/animal effects.
This report explains genetically modified food (GMOs) and discusses the benefits and risks associated with the consumptions of GMOs. Genetically modified foods (GMOs) are foods that have been genetically altered using engineering techniques. The most common technique used today is called recombinant DNA technology; this technology combines different molecules from different plant species to create a plant with a new set of genes, a hybrid plant. Another recombinant DNA technology being used is recombinant bovine somatotropin (rBST) an artificial growth hormone; this hormone is being fed or injected into cows to improve milk production.

Genetically modified foods are a controversial subject in today’s society. A genetically modified food is the result of biotechnological procedures that allow the genetic makeup of a food or organism to be altered in some way. They benefit the human race in many ways but they also pose many risks to the health of humans and the good of the environment. There is currently not enough proof to ensure the safety of these genetically modified products. Consuming these genetically altered and more processed foods can lead to increased
GMOs in food were first approved for human consumption in 1994, in America. GMOs or Genetically Modified Organisms are any organisms with altered genetics that would not occur naturally. The safety and use of GMOs are a major subject up for debate. GMO’s have negative effects on the body, environment, farmers, and animals. GMO’s affect the health of the human body negatively. Some say that GMOs are rigorously tested anywhere from 7-10 years before produced which ensures quality and safety of the products. On the other hand Judy Carman, PH. D. and director of the Institute of Health and Environmental Research, Inc. (a research institute focusing on the safety of genetically modified food), says, “very little safety testing is done on genetically
Genetically Modified Plant's can increase crop yields, they are resistance to pests and herbicides, and GMO plants stop the use of many pesticides. But there are drawbacks to these benefits. For example, field studies conducted in India found Bt cotton demonstrated a higher crop yield, but, "By 2004, however, farmers who had been growing Bt cotton for several years found that the benefits of the crop eroded as populations of secondary insect pests, such as Mirids, increased," (Diaz and Fridovich-Kiel). The new crops tamper with the natural structure of the environment, and attract bug who could eat the plants without dying. Another way in which GMO plants can tamper with the natural environment is bugs can adapt to the new crop. Therefore, the plants create super bugs which can survive the effects of the GMO plants. As a matter of fact, another way GMO plants can corrupt the natural environment is the use of more chemicals to kill herbicides. Some GMO crops are engineered to resist certain herbicides, "However, because HRCs (Herbicide resistant crops) encourage increase application of chemicals to the soil, rather than decrease the application, they remain controversial with regard to their environmental impact" (Diaz and Fridovich-Keil). In other words, GMO's are not only unsafe towards humans, they are unsafe for the natural balance of the environment. We as humans
