Recommended: Environmental impacts of GMOs
For thousands of years, humans have transformed their surroundings and neighboring organisms to suit their needs. The transformation first took place when humans spread seeds onto the earth to grow their own food, and continued when humans reached out to provide food and shelter to other animals in exchange for labor, companionship and sustenance. When early agriculture proved successful, the best and strongest animals and crops were chosen for the next generation. This was the dawn of genetic modification, and it is as old as agriculture itself. When speaking about genetically modified or genetically engineered organisms, an important distinction must be made. This new breed of technology does not use traditional means of gene selection where similar organisms are cross-bred, or where random mutations are used to create a new variety of crop. Genetic engineering technology relies on decoding the DNA of an organism and making delicate adjustments to single genes within a sequence. In many cases, genetic material from vastly different organisms are inserted into the genome of another to produce desired traits. Less than two decades ago, this technology was a controversy that was still in its early stages of development. Today, genetically-modified (GM) crops account for a majority of many crops grown in the United States. GM crops are regarded as one of the most successful commercial applications of transgenic biotechnology (Powell, et al., 2009) and the most widely adopted varieties are those that provide herbicide-tolerance and insect-resistance (USDA, 2009). Although the United States Food and Drug Administration has established that the food produced with this new technology is considered “substantially equiv... ... middle of paper ... ... 1 July 2009.

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.
The technological advances are increasing each year, and electronics are not the only things upgraded. The food eaten in the United States has also been touched by science in the form of GMOs. Although GMOs have been in the US food industry for almost twenty years, consumers should have the right to know what is in our food with mandatory GMO labeling.

Genetically modified organisms are “an organism whose genome has been altered in order to favour the expression of desired physiological traits or the output of desired biological products.” http://www.merriam-webster.com/concise/genetically%20modified%20organism%20(gmo). The United States were first approved for human consumption of genetically modified foods in 1995. The techniques used for producing the genetically developed organisms include cloning recombinant DNA technology. Primary uses of genetically modified organisms are mostly in areas of agriculture and biomedical research. GMOs compromise numerous aids to society, including enlarged crop yields and the development of fresh therapeutic agents which prevent and treat a wide variety of human diseases . However there are some concerns around the use of genetically modified organisms which include the risks stood to human health and the initiation of insecticide resistant superbugs. This essay will provide evidence to support the evidence that the genetic modifications of crops produces better results than selective breeding or mutation.
“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.

Eating is extremely important, it is also important to eat healthy. Most Americans eat without any concerns; they are not questioning or researching what they are feeding themselves or their family. A lot of that has to do with their financial stability, not having the time to prepare a meal due to their time-consuming work schedule, also lack of knowledge and education on what they are consuming. In this bibliography, I will go over all three articles and explain what they are about.
Genetic modification assign to the manipulation of the DNA by humans to change the fundamental characteristics of plants and animals. Genetic modification process happens by taking genetic material from one species and putting it into another, to allow the production of a new quality in a crop or an animal. Qualities such as: new color, new shape and new size. “In North America and Europe the value and impact of genetically engineered food crops have become subjects of intense debate, provoking reactions from unbridled optimism to fervent political opposition.” (Ackerman ,J.A, 2010) .Some people think about genetic modification that it is an essential tool for solving the starvation problem. On the other hand some people think of genetic modification as it has a huge negative effect in the human health and the environment. Genetically modified foods are everywhere around us, they are used by many people daily, although they cause dangerous health problems. Genetically modified foods affect human beings’ health and have huge negative environmental impacts.
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 inserting it into another plant. The new genetically modified plant will now have gained drought tolerance as well.
Not many people have heard about GMOs, heaven knows Elena didn’t. The truth is even though you haven’t heard of them, you have probably eaten GMO foods at some point in your life. From being called frankenfood, to maybe ending hunger in certain countries, GMOs have many benefits and many drawbacks. Whether or not you are pro GMO or say no to GMOs, you have to know what they are first.
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.
In this day and age, Genetically Modified Organisms (GMOs) have become a topic of large interest in the media. GMOs are defined as an organism whose genetic structure has been altered by incorporating a gene that will express a desirable trait (Dresbach et al. al. 2013). Often times, these traits that are selected are either beneficial to the consumer or producer. Currently, GMOs are being created at a higher rate than ever before and are being used in the foods that we eat.
If crops were affected by droughts, disease and insects, having destroyed many acres across America’s Midwest region, the use of Genetically Modified Organisms (GMOs) would not be beneficial in regenerating new crops. Genetically modifying foods (GMOs) “are plants or animals that have been genetically engineered with DNA from bacteria, viruses or other plants and animals that cannot occur in nature or in traditional crossbreeding” (nongmoproject.org). Most research done has concluded no positive benefits in using GMOs. There are serious health risks associated with eating GM foods based on scientific research done around the world. The purpose of GMOs are to increase production of crop yield and reduce pesticide use but research says otherwise. If farmers wanted to continue using GMOs to produce crops, labeling should be mandatory to allow consumers to have a conscious choice whether or not to eat GM food. Through research it has been proven that the use of GMOs to increased production of crops during a time of drought or disease have no benefits, just risks.
The most wonderful activity a human being can experience is new flavors and foods. For example, the first time a person tastes a delicious juicy piece of prime rib or a delightful hamburger with cheese and ham, his world is never the same. However, since the beginning of the twentieth century, the production of food has been supplemented by science. This has triggered an angry dispute between the people who support the advances of biotechnology and people who love nature. In order to understand the controversy, we have to know the meaning of genetically modified foods. With new technological advances, scientists can modify seeds from a conventional seed to a high tech seed with shorter maturation times and resistance to dryness, cold and heat. This is possible with the implementation of new genes into the DNA of the conventional seed. Once these "transgenes" are transferred, they can create plants with better characteristics (Harris 164-165). The farmers love it not only because it guarantees a good production, but the cost is also reduced. On the other hand, organizations such as Greenpeace and Friends of Earth have campaigned against GMO (“Riesgos”) because they think that they are negatively affecting the earth (Gerdes 26). Both the advocates and the opponents of genetically modified foods have excellent arguments.
...ound in the organism. An example would be that organisms are currently on the market and also include plants with the resistance to some insects and also plants can also tolerate herbicides and also crops with modified oil contents. (Biosafety, 2005) Genetic engineering was found to be a changing of an organism. The first big success of genetic engineering was found to be the production of insulin which is a hormone which is produced by the human’s pancreas by something called genetically modified bacteria. Then today’s genetic engineering techniques are used in a lot of different areas.
