Genetically Modified Food Research Paper
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

Weeds are developing resistance to herbicides, because the modified seeds can withstand certain herbicides and pesticides. The increased resistance of weeds to pesticides shows why GMOs are at fault. [In] the [1990s], with the introduction of GMOs engineered to resist glyphosate, the genetic resistance of many weeds to it rose [fiercely].”(Vatnick). Also foods that were genetically modified were shown to have odd effects on animals around the world. “Rats that were fed GM potatoes developed potentially pre-cancerous cell growth, damaged immune systems, smaller brains, livers and partial atrophy of the liver. Rats fed GM soy showed odd-shaped nuclei in their livers. Pigs [that were] fed GM corn [developed] false pregnancies. Similarly, twelve cows fed GM corn died mysteriously.”(Barbour 110) Eyewitness reports from all over North America describe how several kinds of animals when given a choice, avoid eating GM foods. Another criticism of GM foods is that it places the control of agriculture into large conglomerate companies and detriments small farmers. Expensive patented seeds make it impossible for farmers to compete with these large companies, while furthering the gap in between the wealthy and the poor . “[In] 1996, a patent for quinoa, a high protein grain traditionally grown in the Andes, was issued to the Colorado State University for biotechnology experimentation. If the U.S. began to grow quinoa, Bolivia's one million export industry
Whilst some refer to transgenic organisms as, “Frankenfoods”, the proponents see this as the second Agricultural Revolution. Biochemists cite the classical example of a transgenic banana which could produce vaccines as a means to continue their research. Undoubtedly if such a banana did exist it could potentially provide millions if not billions of people access to vaccinations. The chair of the Food and Agribusiness Institute at Santa Clara University states, “Bioengineering is just a more refined process [of selective breeding], which will probably result in more productive animals and plants at a lower cost than traditional breeding methods.” This “more refined process” has served to create corn, which is resistant to pests such as corn borers; tomatoes, which can resist cold temperatures and have increased traveling durability; and arguably the most important, cattle which is resistant to mad cow disease. Aside from the clearly visible genetic advantages provided by transgenic organisms, proponents further cite the colossal economic impact of GMOs. PG Economics issued a report which reveals the net economic benefit at the farm level in 2011 was $19.8 billion, and over a 16 year period from 1996 to 2011 the global farm income gain was $98.2 billion. This 16 year period coincides with the adoption of transgenic cropping systems.
The word GMO stands for Genetically-Modified Organism and can also be referred to as Genetically Engineered foods, Genetically Modified Foods, and Biotech. Genetically engineered foods are created when one desired trait is isolated and introduced to another plant by inserting the certain gene. The process, considered genetic breeding, and is much more precise than the regular breeding. While GMOs have been in food for 20 years, currently, the controversy and genetically engineered farms are larger than ever. 82% of Americans want GMOs labeled, but majority fail to understand them (Swanson). 90% of all US grown corn, canola, soybeans, and sugar beets have DNA bits from the lab (Woolston). The United States is the top GMO growing country with 70 million hectares of land dedicated to these farms. (Lee). These modified crops and plants for human and animals are created mainly for withstand herbicides or to produce an insectide. “No GMO traits are on the market for bigger yields, drought resistance, enhanced nutrition or any other consumer benefit” (Burnham). Overall, GE foods’ main purpose is to save money for large corporations.
In an article titled “The Threats From Genetically Modified Foods” by Robin Mather, he has said that the use of glyphosate, a herbicide, can “significantly increase the severity of various plant diseases” which is very hazardous to the environment. In the same article “The Threats From Genetically Modified Foods” Robin Mather has stated that genetic transfers cannot occur in nature and are not so precise and predictable as people say they are. In another article called “Biotechnology and Genetic Engineering” from Issues & Controversies, it has been shown that genetic modification can affect many plants. For instance, the article stated that In Oregon, there was genetically modified grass that had affected plants nearby which began to ruin all of the crops near the genetically modified
Genetically modified foods or GM foods are foods that have been changed to improve the size of the product and to progress the efficiency of food production. Genetic engineering can be done on both plants and animals and are processed to make the desired characteristics that are required for selling. Genetically modified food has become a controversial topic because people have different viewpoints on which type of food is better for their health. Many protests were created to ban genetically modified foods because of the harm that it caused to the people and the environment. Although people have different opinions towards this topic, there are numerous advantages and disadvantages in producing and consuming genetically modified foods.
...to be resistant to the company's own Roundup herbicide This means that farmers are utterly dependent on Monsanto; a situation similar as with the United States. The biggest adversaries of GM soybeans are environmentalist. For example, floods are happening because of soya farming in the region of Santa Fe and Chaco where the Salado River begins. The deforestation and the low permeability of the soil used in soya farming contributed to more channeling more water into the river. On the other side, people claim that GM crops are required to fight hunger in poor and developing countries. Evidence shows otherwise. GM crops have increased the use of pesticides while increasing poverty. Over 170,000 famers have had to quit on their lands because they couldn’t compete with big GM farmers, thus leading to more poverty. Also, herbicides have introduced new health problems.
Meanwhile, detrimental effects of GM seeds might outweigh their benefits. There is lack of researches that can gauge the long-term effects of GM seeds on humans and animals’ health. Critics blame glyphosate which is the main ingredient of Roundup herbicide for causing harm to farmers’ health and also the surroundings because of its lasting residues. In addition to the drawbacks of GM seeds, organic farmers stated that GM products will contaminate their conventional seeds and the combination between those seeds can create mutative one which poses a threat to the
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.
GMOs have their pros and cons, but in terms of their effects on biodiversity, the technology is almost solely negative in how it affects the environment. Genetically modified food can damage agriculture as it allows for less restraint on chemical usage which leads to stronger weeds and weaker soil. The crops can easily spread their genetically modified genome through the wind. GMOs damage living organisms by making nasty insects stronger and vital insects weaker. GM foods are correlated with the decline in mammal and bird health and the introduction of GM animals like salmon poses a threat to the ecosystem of wild fish. GMOs can also bear consequences in terms of genetic pollution and alteration through contamination and mutation to adaptation to evolution to species extinction. Indeed, some claims are not well supported and may require testing, like genetic alteration through consumption or the validity of correlating animal health deficits with GM feeds. However, overall, GM foods clearly affect the world negatively in terms of biodiversity and ecosystem impacts.
Scientists have been changing genomes of plants and animals by integrating new genes from a different species through genetic engineering, creating a genetically modified organism (GMO). Consumers in America have been eating GMOs since 1996, when they went on the market. There are benefits to genetically modifying crop plants, as it improves the crop quality and increases yield, affecting the economy and developing countries. But there are also negative effects from GMOs. Consumption of GMOs has various health effects on both body systems of animals and humans. GMOs also affect the environment, ecosystems and other animal species. The cons outweigh the pros in the case of GMOs.
This has created a large amount of debate on local, national, and international levels about the safety of genetically modified foods to human health. There are many angles that have been taken from different groups on this issue. Some believe it is harmful to our health, with one source stating that, “mice eating GMO corn had fewer and smaller babies (Jagelio 2013).” Without testing on humans how are we to know these harmful effects aren’t impacting our health and reproduction. Other groups see GMOs as being both beneficial and having no impact on human health.
An English doctor, named Arpad Pusztai, did a study on rats being fed genetically modified foods. His study found out that rats that ate genetically modified potatoes had pre-cancerous cells, smaller brains, smaller livers, smaller testicles, and damaged immune systems. After finding this out, he then changed the eating habits of the rats by interchanging between feeding them organic potatoes and genetically modified potatoes for two weeks at a time. He concluded that whenever the rats ate the organic potatoes, their symptoms disappeared, but when the rats ate the GMO potatoes again, the symptoms reappeared. Pusztai study isn’t the only that proves that GMOs are harmful. Other studies have also shown that GMOs are linked to reproductive problems, immune system problems, accelerated aging, gastrointestinal distress, and dysfunctional regulation. This proves that GMOs have a serious effect on our
In conclusion, the application of genetically modified food has a lot of pros and cons. There is so much disagreement about the benefits and risks of GM because there are so many different views surrounding it. This issue is very important today because it will change our future. How would the world be when every single living creature will be in some aspect genetically modified? Would we be more resistant to illness? Or would we be weaker and more vulnerable to diseases? Would this be the beginning of the mutant era? Regardless of the answers to these questions, we will need to consider the implications of genetically modified foods.
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. (ThefreeDictionary)
“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.
Genetically modified (GM) foods have become omnipresent over the past decade. They are a technological breakthrough that allows humans to manipulate and add foreign genes to crops to enhance desired traits, but they have also evolved into a controversial issue, especially for Third World countries. Some people believe that GM foods not only provide larger yields to feed hungry citizens in Third World countries, but they can also be a source of great nutritional value. For example, researchers have developed a strain of golden rice containing high amounts of vitamin A and numerous other vitamins and minerals. Additionally, GM crops are laced with herbicides and pesticides, and therefore reduce the need for chemical consumption. Opponents of GM foods claim that they pose a threat to the health of consumers and that these crops could eventually cross-pollinate in an unregulated fashion or lead to the growth of superweeds and superbugs resistant to the herbicides and pesticides woven into the genetic fiber of the crops. Developed nations should promote research and monitoring from an ethical point of view and financial assistance through philanthropic ventures in order to limit environmental and health risks. They should also make sure that limited cultural displacement will result from the introduction of GM crops and that instead, a better livelihood and well-being through collaboration will emerge. Hence, GM crops should be introduced only provided that the developed nations assume the ethical and financial responsibilities for the environmental, health, and social consequences that attend this new innovation.
