Genetically Modified Crops
1. Introduction
It is ironic that some individuals, strongly supporting fresh, organic natural vegetables to be delivered to their dinner tables, enjoy purchasing genetically modified crops that make their lives easier. The United States of America is one of the most prominent countries where genetically modified crops are widely adopted, in contrast to Europe where genetically modified food has never gained approval from the public, and Japan where no genetically modified crops are grown commercially. Despite the significant improvement in agriculture since the introduction of genetically modified crops, little is known to the common about its specifics and arguments for its use. Genetically modified crops are a positive influence to the society, which can be seen through understanding its fundamentals and comparing the pros and cons of such technology.
2. What are GM crops?
The term genetically modified (GM) crops or GMOs (genetically modified organisms) or even GM food is most commonly used to refer to animals, plants or microorganisms that have had their genes altered through the insertion or deletion of transgenic genes to produce desired traits. These plants are genetically modified to enhance or even introduce desired traits such as increased resistance to herbicides and pests, improved nutritional content and adaptations to harsh or hostile environments. The enhancement of desired traits of crop plants is not something new. This had been done millennia ago through selective breeding and grafting, but this conventional process can be very time-consuming and are often ineffective or inaccurate. On the other hand, through genetic engineering, crop plants with desired traits can be cultivated qui...

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...

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.
Thesis: Genetically modified organisms have the potential to benefit the field of agriculture as they are continuing to make advancements that should not be hindered. GMO foods should be supported because they are safer, since they utilize fewer herbicides and pesticides, produce larger yields that can reduce world poverty, and can help fight vitamin deficiencies and malnutrition.
We see the fruits of years of genetic research all around us. Genetically modified foods are everywhere. Biotech seeds yield a hefty portion of the corn, tomatoes, soybeans and other agricultural products and derivatives consumed by the American population on an annual basis (2000, Sunstein). Over 70% of the items Americans find on their supermarket shelves contain genetically modified content (1999, Wastell). We did not get to this point without endless hours of research and testing by dedicated scientists and researchers. This technology however is not without its opposition, in Europe genetically modified food products are aggressively regulated and labeled (2000, Sunstein). Papers have been written that allegedly show these crops not only damage the ecosystem as in the case of the Monarch butterfly but also are a danger to the animal or human who would ingest them as cited by Dr. Arpad Puzstai (1999, Lean).
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.
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 Organism was introduced to the public approximately fourteen years ago. Genetically Modified Organism was brought about through Plant Biotechnology, which has been researched for centuries. Farmers’ crops are everything to their business, and wanting to preserve their product is top significance. A solution to the numerous possibilities of hindrance genetically modified organism was spawned. Traditional breeding included different processes, such as sowing seeds from the resilient plants in order to produce a new generation. Farmers would grow plants with higher yield and resistance to pests, naturally alternating the genetic makeup of plants. Consequently, a vast majority of plants today bare resemblances of their lineage (Biotechnology Industry Organization 2010). Plant biotechnology allows breeders to sel...
“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 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)
Food has played a vital role in our lives since the beginning of time. It gives us energy to live, supplies us with nutrients, and helps us grow and develop. However, with our growing population, growing enough food for everybody has become tough. In the past few decades, scientists have been formulating new ways to boost the benefits and quantity of foods by altering the genes inside the food. These “frankenfoods” are called genetically modified organisms, more commonly known as GMOs. GMOs have some benefits, for example, creating extra vitamin A in carrots to improve the eyesight of people in less developed countries. They can also aid in the production of food, such as creating resistance to pests and herbicides. Although this technology is quite helpful, there is a large debate going on discussing the safety
Several decades ago farmers used to grow their crops naturally using traditional methods until the early 1990’s when a Californian company established the first commercially genetically modified food which was a tomato. During those days it was commonly referred to as the flavrsavr and it had been genetically altered so that after it had been harvested it would last longer before it decomposed. Nowadays it is becoming common to find scientists and farmers working together in this growth industry of genetic modification. There is certainly no doubt that nearly three quarters of the Australian people are unaware that they are consuming genetically modified foods. With the increase on debates regarding whether genetically modified foods cause health risks to humans there is no doubt how controversial this issue is.
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.
Consuming foods that have been genetically altered have serious health risks based on research done on rats by The American Academy of Environmental Medicine (AAEM), an international organization of physicians. Risks include infertility, immune system problems, accelerated aging, disruption of insulin and cholesterol regulation, gastrointestinal problems and organ damage. Many AAEM physicians have prescribed non-GMO diets for all patients to improve health conditions. Jeffrey M. Smith, an advocate for non-GMO, says scientific research shows the link of GM food to thousands of sick, sterile, and dead livestock; thousands of toxic and allergic reactions in humans; and damage t...
