Genetic engineering (GE) is the modification of an organism’s genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. When gene transfer occurs, the resulting organism is called transgenic or a GMO (genetically modified organism).
Genetic engineering is different from traditional cross breeding, where genes can only be exchanged between closely related species. With genetic engineering, genes from completely different species can be inserted into one another. For example, scientists in Taiwan have successfully inserted jellyfish genes into pigs in order to make them glow in the dark. F

Since no genetically engineered animal products have ever been approved by the FDA, the pork products that reached supermarket shelves were technically illegal for human consumption. As a result of the accident, the FDA sent letters in May 2003 to all land-grant universities, reminding researchers that their work "may require" licensing under the animal drug law. F
What are the concerns over GE food?
Many concerns have been raised over the inadequate testing of the effects of genetic engineering on humans and the environment. Genetic engineering is still an emerging field, and scientists do not know exactly what can result from putting the DNA of one species into another. The introduction of foreign DNA into an organism could trigger other DNA in the plant or animal to mutate and change. FIn addition, researchers do not know if there are any long-term or unintended side effects from eating GE foods. F
Critics of genetic engineering believe that GE foods must be proven safe before they are sold to the public. Specific concerns over genetic engineering include:

Genetic engineering may change the nutritional value of food. F
Environmental Damage. Insects, birds and wind might carry genetically altered pollen to other fields and forests, pollinating plants and randomly creating new species that would carry on the genetic modifications.
Gene pollution cannot be cleaned up.
Once released into the environment, genetically engineered organisms cannot be cleaned up or recalled. So, unlike chemical and nuclear contamination, which can at least be contained, genetic pollution cannot be isolated and separated from the environment in which it is spreading.
Superweeds
GE crops can cross-pollinate related weed species, passing on their ability to survive the application of weed killers. Even without passing on that specific genetic trait, the widespread adoption of GE crops that are resistant to herbicides like Roundup has led to dramatic increases in the use of this weed killer, and weeds have gradually developed resistance to the herbicide. This leads to the evolution of superweeds that are very difficult to control. Already, superweeds have infested 12 million acres in the United States. FAt least 20 weed species worldwide are resistant to Roundup, including aggressive weeds like ragweed, pigweed and waterhemp.
Barbara Kingsolver discusses genetic manipulation through generations of different species in her essay A Fist in the Eye of God. These genetic manipulations occur due to the species acclimating to their environment. Diversity in genes is nature’s survival of the fittest. Only the strongest survive and they pass on their strong traits. With today’s technology, we have the capability of altering genes within a species DNA. This paper examines the detrimental repercussions that GMO 's cause to the environment and insects necessary for the progression of crops.
In The Case Against Perfection, Sandel warns us of the dangers that genetic engineering, steroids, and hormones poses to society and the natural order. According to Sandel, this type of control, especially in non-medical settings, violates a respect for life that should be ingrained in all of us. Life is something difficult to predict, something that shouldn’t bend to our every single will and desire. Genetic engineering, and the like, presents an egregious violation of this respect. According to Sandel, this violation serves only to reverse the human march of progress. Sandel weaves a well-balanced argument in his book. The issue of eugenic technology is most definitely not black or white. According to him, the aspects of modification can be applied selectively, so long as it doesn’t violate the respect for life society should hold closely.

Some people have raised concerns to the topic about genetically modified foods, but there are pros and cons to both sides. People worry about their lives being in danger from consuming genetically modified foods and the allergic
...y modified organisms can not only infiltrate our ecosystem and threaten the natural processes but they can also impose health risks for the living in various areas. In closing, it is important to be aware of the benefits and limitations of genetically modified organisms. The real question is do you want them in your life?
Genetically modified foods have a huge impact on our environment. One way that genetically modified foods are hurting our environment is that process can involve the exchange of genes between two totally different species. People are actually putting scorpion toxin into corn and fish antifreeze into tomatoes (De Greef). These changes in the plants make the plant able to with stand the attack of pests and weather, but it is still possible that the plant’s DNA will cross and make bad toxins. If a farmer plants a crop that has the resistance to herbicides, drought, cold, and pests those plants can eventually cross with weeds and then the farmer will end up with weeds that are resistant to everything too. Then the scientists will end up having to make the plants stronger to fight off the weeds, then the weeds will get stronger, and the cycle will keep on going. Another argument for the ban of...
Genetic Engineering has recently become a contentious topic within medical and social circles. Controversial topics such as Sex Selection and Designer Babies are linked to Genetic engineering. They are destructive in every circumstance. Genetic Engineering is detrimental towards the individual and all posterity.
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
Modern technology has taken amazing strides in the past few years. We have changed the way we deal with food production, agriculture, and many other aspects of life.. Scientists have begun utilizing these advances in technology and knowledge to gain insight as to how the human species functions. They are on the verge of manipulating the way humans relate to the natural world. This revolutionary breakthrough is what is known as Genetic Engineering. Genetic Engineering is the process of manually adding new DNA molecules into an already existing organism. A simplified version of the process works by physically removing a gene from one organism and placing it into another. This is being done in an effort to
Genetic engineering, sometimes called genetic modification, is the process to alter the structure and nature of genes in humans, plants, and animals (what is genetic engineering). Because DNA is a code that is universal, genes can be manipulated
Genetic Engineering is the deliberate alteration of an organism's genetic information (Lee 1). The outcome scientists refer to as successful entitles the living thing’s ability to produce new substances or perform new functions (Lee 1). In the early 1970’s, direct manipulation of the genetic material deoxyribonucleic acid (DNA) became possible and led to the rapid advancement of modern biotechnology (Lee 1).
Human Genetic Engineering: Designing the Future As the rate of advancements in technology and science continue to grow, ideas that were once viewed as science fiction are now becoming reality. As we collectively advance as a society, ethical dilemmas arise pertaining to scientific advancement, specifically concerning the controversial topic of genetic engineering in humans.
Genetic engineering has been around since the 1960’s although major experiments have not been really noticed until the 1990’s. The science comes in different forms the two major being cloning and genetic reconstruction. Cloning is the duplicating of one organism and making an exact copy. For example in 1996 the creation of the clone sheep named Dolly the first mammal to be cloned which was a great achievement. The other form, genetic reconstruction, is used to replace genes within humans to help or enhance the life of an unborn child for a medical reason or just for the preference of a parent.
Scientists and the general population favor genetic engineering because of the effects it has for the future generation; the advanced technology has helped our society to freely perform any improvements. Genetic engineering is currently an effective yet dangerous way to make this statement tangible. Though it may sound easy and harmless to change one’s genetic code, the conflicts do not only involve the scientific possibilities but also the human morals and ethics. When the scientists first used mice to practice this experiment, they “improved learning and memory” but showed an “increased sensitivity to pain.” The experiment has proven that while the result are favorable, there is a low percentage of success rate. Therefore, scientists have concluded that the resources they currently own will not allow an approval from the society to continually code new genes. While coding a new set of genes for people may be a benefitting idea, some people oppose this idea.
Genetically Modified Organisms (GMO) is an organism, such as a plant, animal, or any microorganism who’s had its DNA changed in different ways through genetic engineering that is not natural. It is an organism like every other organism, which produces thousands of proteins, but one or two of them are proteins that were chosen were specifically by humans. It creates unstable combinations of plants, animal, bacterial, and viral genes that do not occur in nature or through traditional crossbreeding methods. Majority of Americans in the US consume nearly 200 pounds of GMOs each year. 90% of US crops are genetically modified.
