There are many positive views on the genetic altering of corn. Consumers always look for the shiny, beautiful food with delicious taste. By genetically engineering corn, it can become sweeter and have a better overall appearance. (16) Along with this pleasing appearance, comes its improved resistance for insects, disease, and other pests. This means that new forms of corn now possesses the ability to overcome pests and even weeds that once weakened or killed the young plants. As a result, corn can be grown where there used to be a lot of infestation. (13) In the process, this would also kill insects. Furthermore, corn has more nutritional benefits. Corn now has additional vitamins and minerals because of genetic engineering to provide greater
Genetically modified? That alone should be a cause for alarm, and have you wondering, what exactly is in this that I am eating? Yet every day millions of American’s choose to load up on food filled with GMO’s, and not even know it. First we must understand what GMO’s are. GMO’s are any organism whose genetics has been altered using genetic engineering. We should not be tampering with nature, and should try to grow organically as much as possible. There has not been enough research on GMO’s to know the potential long term effects it can have on us, so this is why GMO’s should be banned.
In the first third of the book, The Omnivore’s Dilemma, by Michael Pollan, he draws the reader in by bringing to light many interesting facts about corn that most individuals may not realize. He states that the majority of food that people consume contains corn. Although people of Mexican descent are usually referred to as the “corn people”, Americans have now surpassed them in the amount of corn consumed in their daily diet. Corn is consumed in a variety of forms and many of the animals that are eaten by Americans, such as the chicken, pig, turkey, and lamb are fed corn. When a person eats these animals, he or she is essentially increasing their corn intake, and in most cases without even realizing it. The corn crop has spread vastly and is massively produced because it is efficient. Unlike other crop plants, corn can survive in harsh weather conditions and it is light and easy to transport. Maize is also self-fertilized and pollinated by wind, and it has evolved over time and continues to evolve, into new forms and new uses.
In his article “No, You Shouldn’t Fear GMO Corn” published at Slate.com in 2012, Jon Entine argues that genetically engineered crops pose no harm to health or environment, and the conclusion Caitlin Shetterly made is absurd and holds no water.
One of the most prominent crops in the GMO industry is Bt corn. The Bt pesticide stands for Bacillus Thuringiensis. Scientists transferred the Bt gene into the corn to create a crop that produces its own pesticides. As the corn matures, it grows stronger poi...
Pamela Ronald, a plant geneticist, presented a Ted Talk “The case for engineering our food”, Ronald points out that engineered genetics for our plants is not harmful, yet better for our environment and health. “Now, genetic modification is not new; virtually everything we eat has been genetically modified in some manner”(Ronald).
The audience that my paper would pertain to would be Scientists. In today’s society many scientists have been researching the positives and negatives of GMO products. These scientists are involved in this topic due to the intense debate and amount of new information that had yet to been discovered. The reasons many scientists are interested in this topic would due to many saying there are health risks that come with eating GMO products. The views that these professionals hold that will help me would be their position or authority on the subject. Also their view on the subject can also help when needing a valid opinion on the subject.
“Civilization rests on people’s ability to modify plants to make them more suitable as food, feed and fiber plants and all of these modifications are genetic” (American Association 1). This quote from the article “Statement by the AAAS Board of Directors On Labeling of Genetically Modified Foods” expresses that fact that humans have used the favorable genes of plants since the days of Gregor Mendel, the father of genetics. When plants exhibited a desirable trait, they were bred together so that more of the offspring would have that trait. Genetic Modification is manipulating the genome of the plant, but humans have been doing that for years. Modifying the genes is a more precise way to do this. Genetic Modification improves food and is safe.
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.
The question “Is this product genetically modified?” has gained increasing popularity among the health concerned and those who worry about where their food comes from over the past couple of years. A decade or two ago, this question had no meaning and has no significance in society. However, thanks to the development of technology and a larger understanding of the underlying properties of foods, down to the molecular scale, humans have created a new field of engineering to combat worries that have plagued the food industry to centuries upon centuries. And as always, the advent of a new a product or procedure that changes the way we think and create will always usher along with it self opinions from every strata of society. The genetic modification of food in the United States of America has become a pertinent topic of debate, just recently gaining its popularity in the past couple of years. To modify or not to modify? There are both pros and cons to whether or not change the DNA sequences of foods in order to better them in some way or another. However, like every other major, groundbreaking change in this country comes regulation in hopes to appease everyone in the country and give each participant a fair chance in the race, in particular, the race for the production and distribution of foods. Such regulation in the United States has been done in order to protect and support people that have not devoted their time and money to the biological nuance and also to give every consumer in the country products that are labeled, identifying what they are putting into their systems on a daily basis. As time and society progress, how we view tasks that have been usually kept hidden and now placed onto a pedestal for everyone to se...
"Whoever could make two ears of corn, or two blades of grass grow upon a spot of ground where only one grew before would deserve better of Mankind, and do more essential service to his country, than the whole race of politicians put together." -The King of Brobdingnag, Gulliver's Travels by Jonathan Swift, 17271
The term ‘genetic engineering’ covers several methods of manipulating genetic material, otherwise known as genetic manipulation; recombinant DNA technology and gene therapy in humans (Atkinson, 1998). This technique is not only used for genetic transfer between plants but, genes from non-plant organisms can be used as well. A known example of this is the transfer of the B.t gene found in corn and other crops. The B.t gene, or otherwise known as ‘Bacillus thurngiensis (Bt)’; is a naturally occurring bacterium that creates proteins with crystals that are fatal to insect larvae (Whitman, 2000). These B.t genes have been transferred into the corn, allowing the corn to effectively produce its own pesticides against insects.
According to scientists, genetically engineering crops contributes to their quality. Crops that have been genetically modified to have a particular trait can decrease the amount of herbicides needed for growing that crop. Additionally, genetically modified (GM) crops can help third world countries, where malnutrition is common. For example, to help diminish nutrient deficiencies in developing countries, “plans were underway to develop a golden rice that also has increased iron content”(Whitman 2). In addition, GM crops can be modified to be able to “withstand the environmental challenges of drought, disease, and insect infestation” (Swenson 1). Growing GM crops can also result in fruits and vegetables that stay fresh for a prolonged period of time and taste better.
Genetically modified organisms (GMOs) are a cause of continuous debate. What would be the purpose of producing genetically altered food? Many argue that GMOs could prove to be very beneficial, the use of GMOs could lead to advances in medicine, and agriculture, and they could also prevent famine in poor underdeveloped countries. Genetic modification offers many benefits: pest control, disease resistant crops, drought resistant crops, no use of insecticides, nutritional beneficial foods, and less contamination. This is only a short list of the many benefits offered by the used of GMOs. With so many benefits why are we opposed to such a miracle? (NERC 2005)
There are several benefits of genetically modified foods. The world population has reached to seven billion people and it is predicted to become double in the next 50 years. Ensuring an adequate food supply for this booming population is going to be a major challenge in the years to come. Genetically modified foods can make it possible to meet this need in a number of ways such as strong plants, improved nutrition, high crop yields, reduced allergenicity, medical benefits, healthier farm animals, environmental benefits, food safety improvements, and economic benefits. Genetic engineering has been successful in producing plants with increased pest and disease resistance, while retaining high yields, taste, and processing attributes. Fo...
Genetic engineering increases the agricultural economy, the yields of agricultural produce, and also causes negative effects on the ecosystem. Genetic engineering enhances plant resistance to drought, salinity, disease, pests and herbicides. The aim is to try and enhance the growth, productivity, nutrient value, and chemical composition of the plants. Chemicals are constantly being developed or improved to enhance the competitiveness and adaptability of crops, and to kill the parasites and weeds that plague the agricultural sector. . This however is not always good as the plant and the pests then become resistant to these new chemicals, defeating the purpose of it being used.
