GMO IN Food and Agriculture
Genetically Modified foods are produced using genetically engineering techniques. These techniques are used to ‘inactivate’ or add specific DNA traits of a certain organism to the other in order to improve it. These traits consist of increasing resistance against herbicides and pest, cold, and drought tolerance. In 1946, scientist discovered that DNA of organisms could be transferred between each other. The first plant that was GM was a tobacco plant in 1983. By 1994-95, GMO food was introduced and approved for humans to consume in the USA. The first plant approved by the FDA for marketing was a tomato from Flavr Savr’s.
However, humans have been manipulating different crops for thousands of years. By mating together organisms with desirable traits repeatedly, people were able to mold species to meet their dietary needs. Corn is a very good example of this. It used to be a small, inedible tropical grass called teosinte. Ancient Mexican farmers transformed it into corn. Nowadays, we know this was a manipulation of the DNA of the teosinte plant. This process is called artificial selection and it has transformed all kind of unappetizing plants edible (wheat, rice, almonds, bananas).
In modern days genetically modified foods have changed. Now, the speed and precision we can make changes has increased. According to Eric R. Olson, Scientific American editor explains, instead of selectively breading food traits, we can go directly to the DNA responsible take it out, and transplant it into newly developing plants or animals. When these snippets come from the same species, the new organism is cisgenic (the same). And the organism is transgenic (trans=cross) if the DNA comes from a different plant or animal. For the past years we have seen example of transgenic pairings, such as: corn that makes bacterial toxins poisonous to pests, tomatoes that make the antifreeze protein from fish and even cows that can make human milk.

    A GMO might be a bacteria, plant, animal, or humans, who’s genetic might be changed using modern laboratory techniques. A GMO is a living organism that can develop and duplicate and can expand through its genes and be modified genes to its duplicates. Genetically modified organisms are a very controversial subject in society today as this is commonly used in products consumed by the general public as food sources. This can include fish, oils, vegetables, fruits, and even yeast and grain products. The need for the modification within food sources is noted by an increase in population and a more cost effective way to feed the vast public.…

    With the amount of genetically modified foods in our supermarkets, the research and development of these products should be extensive. On the contrary, there is a shortage of adequate research on the issue of genetically modified foods being safe for human consumption. In a court proceeding against Monsanto, the reason for a general lack of evidence is that they require agreements between the seed growers and the seed producers concerning certain stipulations against outside scientists doing the necessary research. These agreements allow the research to be done only by the company’s scientists, whose salaries are paid by the company. “As a result of restricted access, no truly independent research can be legally conducted on many critical questions regarding the technology” (Tollefson 55). We have a right to know what we are eating and how our government is making decisions about what kinds of food stores and companies are selling us. This information could only benefit the public health; we are being kept in the…

    During the course of this lab, we explored whether or not certain processed foods contained Genetically Modified Organisms. Genetically modified food is an important subject in the world today. Ever since Flavr Savr came out with their tomatoes grown from genetically modified seeds in 1994 genetically modified foods has become ever more popular amongst distributors of produce (Mestel, 2013). The world’s population has grown by around one billion in the last decade (US Bureau of the Census). At this rate, Genetically Modified Organisms within food products will increase dramatically, but is this for the best? There are many risk factors that have been brought up with genetically modified foods such as potential increase of cancer according to a French study conducted by Dr. Giles Eric Seralini (Kilham, 2012).…

    Many opponents of genetically modified foods doubt the safety of those artificial foods. They are the products of people’s intelligence and creativeness, but compared to the eternal law of the nature, human knowledge is not always right. People make mistakes, and sometimes they do not notice about these mistakes until the problems arise. Though developers and manufacturers make sure that there are various advantages of consuming genetically modified foods, due to the potential genetic defects or problems in these foods, they may still damage humans' bodies and undermine the environment. Regarding their benefits such as variation of food choice and the decrease of the cost of food production, genetically modified foods do bring improvements to our…

    My research topic will examine the effect of Monsanto’s current monopoly over the majority of America’s food supply, regarding Genetically Modified Organisms. First, I will reveal how Monsanto’s sustainable agricultural mission statement is crooked, based on myths and false assumptions and instead they’re responsible for large-scale government corruption. Biotech companies have the majority of society completely oblivious that they’re using us humans as test subjects for the largest feeding experiment in history with unknown and possibly disastrous consequences for our health and the environment. Finally I will address how the GMO giant Monsanto has consolidated its power to single handedly corrupt and take over regulatory agencies such as the USDA and FDA.…

    A genetically modified food or GM food product is defined as “meat and edible plants modified through genetic engineering” (Genetically Modified (GM) Foods, 2015). Furthermore, human beings have engaged in the process of genetically modifying plants and animals, with selective breeding practices within identical species, “since the beginning of civilization” (Genetically Modified (GM) Foods, 2015). However, current methods of genetic modification can cross species boundaries, which require suppressive techniques to ensure the foreign genes are accepted by the target plant or animal (Genetically Modified (GM) Foods, 2015). Indeed, this process has led to significant debates regarding the safety of the products that contain GM ingredients and whether these products should be clearly labeled to assist consumers in making an informed choice.…

    GM foods are produced from genetic engineering. Scientists take a certain gene from an organism that is desired and put it into another organism. For example, scientists might take a drought resistant gene from a plant and insert it into a crop, so that crop will not die during a period of low rainfall. There are various ways to add in these desired genes, such as crossbreeding, which has been…

    GMOs: What's the Big Deal?

    • 2868 Words
    • 12 Pages

    In 1953, two scientists, James Watson and Francis Crick, discovered the structure of DNA. Twenty years later, Stanley Cohen and Herbert Boyer developed the first recombinant DNA, through a technique called DNA cloning that allowed DNA to be transferred from one biological species to another. And in 1994, the first genetically modified food available to consumers, the Flavr Savr tomato, which was designed to stay fresher longer, was approved by the FDA (“A Brief History of GM”). Today, GMOs (genetically modified organisms) are in many of the foods we eat on a daily basis. Corn, soybeans, and canola and cottonseed oils are among the top GMO crops. According to author Diana Bocco, approximately 85% of all soybeans grown in the United States are genetically modified, and at least some of the corn grown in every state is GM. Cottonseed oil is not sold as cooking oil, but is an ingredient in many of the prepackaged foods we consume. Canola oil, also known as rapeseed oil wasn’t even used as a food crop until after it had been genetically modified, because it was too bitter. Bocco also notes that another product, called “golden rice” was produced to combat a serious Vitamin A deficiency that affects 250 million people around the world. Scientists added beta-carotene (which the body converts to Vitamin A) to…

    Over the past decade, there has been an outcry over the genetically modified (GM) food industry in America. Some believe that farmers are being forced to use only GM seeds instead of conventional ones. Others claim that GM seeds could have unforeseen effects on wildlife. Still most are criticizing our government’s food safety standards and feel there may be health risks on the people who consume GM foods. Concerns like these and many more regarding GM seeds and foods are being asked by many people. I’m going to discuss the truth about GM seeds and foods and open your eyes to the real effect this industry has on our farmers, the environment, and most of all, our health.…

    The controversial issue of genetically modified foods, commonly known as GM’s, has only gained the attention of millions, since it became a prominent and highly debated global issue. Genetically modified foods are created when the genes of an organism are engineered and modified to create a new or enhanced version of that organism. The process of using different genes from different sources to genetically modify foods led to public outcry and sometimes, praise. People in support of genetically modified foods claims it will enhance the quality of the food, improve the food’s resistance to pests and other harmful elements, lower food costs, and also increase food security for the future. However, those opposed to genetically modified foods claim…
