Abstract This paper discusses the newly discovered phenomenon of geneticallyengineered and genetically modified foods that are being produced, sold and consumed in the United States of America. First, the paper describes and explains this phenomenon by using media sources. Then, it discusses various media sources and the concerns and questions they have regarding geneticallyengineered or modified foods. Finally, the paper notes concerns that neighboring countries, in this case Mexico, have for their own people and environments.
From the Paper "Throughout the history of the United States, science has played a large part in the foods and products that the nation's citizens consume. From new foods that are imported and incorporated into the national crop and diet, to older, standby foods that are improved or used in new or different ways, American eating and consumption has long been shaped by technology and scientific advancement. And, as such shifts and innovations have made their way into the country's fields and barns and supermarkets and onto its dinner tables, the American media has also had much to say, for good or for bad, about how science is helping or hurting the consumers that depend on and utilize such developments."
Abstract The paper explores the dangers of geneticallyengineered food products in the marketplace. It traces activities of anti-geneticengineering groups and their relationship with biotech corporations. Legal and political implications of the industry are also studied.
From the Paper "The new biotechnology of genetic engineering initiates thoughts of a glow in the dark bunny, plants that eat poison, plants that contain pesticides and some medicines. New cures for diseases or solutions to problems that plague the world, such as starvation, are the promises made by the many supporters of this technology. However, many people are skeptical, because they know little of the potential side effects it may have on the people who eat or use the genetically modified products. An article printed in the Christian Science Monitor entitled "Europe Invites Biotech Debate" by Peter Ford on September 11, 2001, explains the position of the public and the European Commission concerning genetically modified products while keeping his view of the issue from influencing the way that he writes. Karen Charman, on the other hand, lets her views of government control give her a clear agenda as to how she states the United States? position in this debate in her article, ?Spinning Science into Gold.? Comparing the biotech issues between ?Spinning Science into Gold,? and ?Europe Invites Biotech Debate,? one sees that, unlike European nations, corporations in the United States maintain exclusive control over genetically engineered products. Clearly there is a need for government intervention to regulate corporations."

Bibliography
From the Paper "In recent years, Indonesia has liberalized its trade regime and taken a number of important steps to reduce protection. Since 1996, the Indonesian Government has issued deregulation packages that have reduced overall tariff levels, simplified the tariff structure, removed restrictions, replaced non-tariff barriers with more transparent tariffs, and encouraged foreign and domestic private investment. The GOI issued a deregulation package in July 1997, which introduced additional tariff reductions."
Abstract The following paper discusses the issue of genetic cloning by looking at its origins and scientific advances.The paper examines the research on geneticengineering and cloning that was used to clone plants, unicellular organisms, amphibians and simple mammals. It looks at significant advances in agriculture, industry and medicine. Although there are many potential benefits to this technology, the prospect of cloning humans has raised many practical, ethical and religious dilemmas that are discussed in this paper.
From the Paper "Genetic engineering is the changing of an organism's DNA, genetic material to eliminate unwanted traits or to produce desirable traits. The earliest form of genetic engineering dates back to the scientist Gregor Mendel who did experiments with peas. He bred only the peas with the most desirable traits in order to achieve a healthier and stronger pea (McCuen 8). This method, called selective breeding, is still used today with plants and animals in order to increase food production. Corn plants are selectively bred in order to produce a larger tastier kernel. Another type of genetic engineering called hybridization or crossbreeding involves breeding animals of different species in order to obtain the most desirable traits of both. Male donkeys are crossbred with female horses to produce mules, which are good work animals (Levine 1). Genes are made of DNA, deoxyribonucleic acid. The discovery of DNA in 1953 by Drs. Watson and Crick led to a much better understanding of the structure and function of genes. Since that scientific discovery many scientists have developed techniques to manipulate the DNA in genes in order to control different genetic processes. In the 1970s, scientists discovered restriction enzymes, which are enzymes that are able to cut and splice DNA. This led to the scientific technique known as recombinant DNA, which has paved the way for more sophisticated types of genetic engineering (McCuen 8)."
Abstract This paper argues for the rights of consumers to know which food products they purchase have been geneticallyengineered. The writer first explains this concept and examines the potential health hazards that people are afraid of when buying such foods. It also looks at opinion of the food producer who is against such labeling due to unbiased fears amongst the consumer population. The paper also addresses the benefits of bio-engineering in certain fields which helps the production process of many food-groups.
From the Paper "In the twenty-first century, with all the pressing issues at hand, there is bound to be controversy and disagreement. There are many important issues, which face the world today, issues like abortion, the death penalty, gun control, censorship, women in combat and even genetically engineered food. With all the modern scientific advances we are making now, especially in the United States there are positive effects as well as negative effects. Genetically engineered foods are very controversial because there are just as many experts who say they are safe as there are experts who say they are unsafe. In the United States about two thirds of all produce on supermarket shelves is genetically engineered; now the problem we, as a nation, face is awareness. Our most relevant issue is whether it should be required to label these unnatural, possibly unsafe foods. And, the answer is yes; the public has a right to know what they are eating and choose whether they want to eat genetically engineered foods, mainly produce."
Abstract The following paper examines the controversial issue of genetically modified foods - particularly as it exists within Canada. The paper discusses how. at present, no law exists to compel labeling indicating that a consumable product is genetically altered. The writer explores how there is a growing sense - and it has existed for nearly a decade in earnest - that such labeling should take place, as well as a more transparent testing process for biotech goods.
From the Paper "In recent years, the furor sparked by the growing popularization of foods that are genetically engineered has led to calls for a serious re-assessment of how in-store products are labeled for consumers. As this paper is written, there are a multitude of everyday foods - cereals, baby food, even ice cream - which contain genetically modified ingredients which have not been tested for human or environmental safety. Quite simply, this is an affront to the right of Canadians to be protected from potentially harmful foodstuffs, and it is also an affront to the right of Canadians to be informed of what precisely they are purchasing for consumption."
Abstract This paper examines the advantages and disadvantages of geneticallyengineered crops and food. The author argues that they have a potentially negative impact on the ecosystem and human health.
From the Paper "While the twentieth century may be known as the century of chemistry and physics, the twenty-first century may well be known as the century of biotechnology. Current technologies enable scientists to create genetically engineered organisms by using the basic building blocks of living matter genes. This ability offers the world a number of advances from curing diseases to human cloning. One of the biggest advances according to some is already here --- genetically engineered crops and foods Genetically engineered crops are new kinds of ..."
Abstract This paper discusses how geneticengineering refers to a number of biotechnologies that are used to combine or manipulate genes or genetic material to produce new physiological traits in the organism or in the next generation. The paper then looks at how geneticengineering includes some aspects of gene therapy, stem cell research, and cloning as well. It also discusses how geneticengineering has come under fire when it has been used in the production of new foods because of the fear that these foods may have unfortunate and unforeseen consequences for the population eating those foods. In addition, the paper discusses other research that has sought to splice genes and manipulate genetic material so as to cure diseases by changing bodily characteristics to fight off the causes of disease. The paper continues with a look at the benefits of geneticengineering and concludes that The field is really in its infancy, and the possibilities are increasing by the day. Each new line of research opens new possibilities for more research tomorrow.
From the Paper "Stem cell research is related to cloning and is also called therapeutic cloning, a term that refers to the cloning of cells the removal of stem cells from the pre-embryo in order to produce tissue or a whole organ to be transplanted back into the person who supplied the DNA. The reason for this is "to produce a healthy copy of a sick person's tissues or organ for transplant," which "would be vastly superior to relying on organ transplants from other people" ("Embryo Cloning, Adult DNA Cloning and Therapeutic Cloning" paragraph 4). For one thing, the problem of rejection is overcome in this manner without the need for specialized drugs. The supply of tissue that could be cloned is virtually unlimited, and this would eliminate waiting lists for transplants."
Abstract This paper provides insight into geneticengineering and gene therapy, the changing of an organism's genes in order to remove unwanted characteristics within an organism or to add other characteristics. In particular, it examines how geneticengineering techniques can be used to identify and treat certain diseases as well as aid doctors in creating custom-made drugs for specific patients. It shows that while the current application of geneticengineering on humans is limited, the hope is that geneticengineering will be able to treat many common diseases. It also describes the controversial issues surrounding its use with doctors, ethicists, religious groups and politicians and examines why science should be careful when applying this technology.
From the Paper "The use of gene therapy began on September 14, 1990 and was use to treat a four-year old girl who was suffering from adenosine deaminase (ADA) deficiency. This is a fatal disease that attacks the immune system. The problem was that her cells were not creating the ADA enzyme necessary for the immune functions of the cells. Doctors at the National Institute of Health in Bethesda Maryland removed blood cells from the patent and modified them with a viral vector from normal ADA genes. When the blood was infused back into the girl's blood stream, the ADA gene programmed the cells to produce the missing enzyme. This helped the girl to develop a resistance to infection, albeit temporarily (Isasi, 2002)."
Abstract This paper explains, starting from the basics, what geneticengineering actually is, and how it is carried out. It details its uses in society and explains the risks involved and how to overcome them. Ethics and social values are included in the discussion.

Introduction
Principles of GeneticEngineering Applications of GeneticEngineering Hazards and Ethical and Social Implications of GeneticEngineering
From the Paper "Restrictions have become less severe over the years, and genetic engineering is being applied more and more as public approval is constantly being sought. Nevertheless, this does not diminish the potential dangers of creating transgenic organisms. For example, consider the use of genetically modified organisms - GMO's - in the general environment, such as crop plants. Can such organisms be used safely? Suppose the pollen of these plants are transferred to wild relatives, thus injecting the gene into a different species. These plants may now act as weeds, and if the crop plants were engineered to be herbicide-resistant, then the weed will be similarly so. When a new type of oilseed rape resistant to the herbicide Basta was produced by the Belgian company 'Plant Genetic Systems' in 1994, there were concerns that rapeseed would act as a weed in hedgerows and would be impossible to control with Basta."
Abstract This paper gives an insight into the principles of geneticengineering since its first concept by an Austrian monk named Gregor Mendel. It discusses how selective engineering of genetics is invaluable to the health and happiness of humans and how the importance of this issue has played second fiddle to the arguments, for and against geneticengineering for years. Examples are provided to argue the positive side of regeneration and to show how in time, genetic disorders such as "Down Syndrome" and "Multiple Sclerosis" could be made diseases of the past.
From the Paper "Even though there are a lot of risks, the possibilities of what we can do are endless. Genetic engineering should be allowed to progress because of the benefits for human beings outweigh the consequences. For example, cows could be genetically cloned to produce milk with medications in it. This means that vaccination shots and pills would become obsolete. Babies could be brought up immune to diseases by simply being fed milk. Imagine what this could mean for people who live in countries like Somalia. Whole countries could be made healthy and immune to disease."

Abstract In recent years, medicine has been so greatly affected by technological advances that it has gone beyond therapy and towards the limits of our imagination. Unlike a few years ago, when conceiving a baby girl or a baby boy was a matter of chance, today's prospective parents can choose to alter the genetic make-up of their children in order to enhance their offspring's well-being in the future. This paper shows, however, that it is not clear if modern society is ready to face the consequences of geneticengineering. On one hand, scientists agree that, from a medical standpoint, genetic technologies do, in fact, hold promising potential. The paper shows that, on the other hand, geneticengineering focused on improvement of the human species involves profound ethical and political risks that are to be taken into serious consideration. The paper argues that not until we become fully aware of the issues surrounding genetic technologies should we pursue the illusion of creating a "perfect baby" and intrude upon our children's lives by intervening with their genes.
From the Paper "What does modern germline engineering have to do with eugenics of the past? Obviously, contemporary genetic technologies are nowhere near encouraging or discouraging certain groups of people from reproduction. However, the science seems to be turning away from its primary purpose of bringing human beings to life free of diseases towards enhancing otherwise normal human beings. This trend looks like a resurrection of eugenics at a more advanced scientific level. Daniel Wikler confirms that people are clearly worried about genetic engineering moving ?from "medical" concern for the individual to "eugenic" ambitions for improving the gene pool in general?(because) this move was accompanied, early this (last) century, by great wrongs, harms justified by the greater good?? (14). Is germline engineering simply a new name for eugenics? "
Abstract This paper gives some background on the geneticengineering of food. The author focuses on the dangers that stem from geneticallyengineered food such as possible medical side effects and repercussions to the environment. The author advocates mandatory labeling of foods with geneticallyengineered ingredients and looks at regulations in other countries.
From the Paper "By far the most severe environmental repercussion of GE crops is that they are a Pandora's box, once they are planted, there is no way to control or recall them. Pollen from GE plants is spread in exactly the same manner as regular pollen, and, therefore, their genetic material will quickly spread to any surrounding fields. This is one of the main reasons why is truly impossible for people to know what they are eating. An organic tomato grown a mile away from a farm that grows GE tomatoes may or may not be infected. Scientists have no way of determining what kind of effects the release of all this genetic pollution will have on the ecosystem (Davis)."
Abstract This paper examines how geneticallyengineered food is food that is produced from geneticallyengineered crops or animals and how the process of geneticengineering occurs when genes from one organism are spliced into the DNA of another organism, creating a new organism that could no come to pass through traditional breeding methods. In particular, it looks at how, because GE foods can be produced in larger quantities and at lower costs than traditional foods, the trend to embrace them seems inevitable and how opponents of GE foods are pushing to ban them, arguing that these foods are dangerous to human health and to the environment.
From the Paper "The argument that GE foods are potentially dangerous, that they may possibly be harmful in some unknown way at some unknown time cannot support the proposal to ban GE foods. For example, recent charges that a type of GE corn found in corn snacks could cause nausea and anaphylactic shock failed to provide the necessary evidence to support this accusation. No clinical case demonstrating such allergic reactions was ever reported. In addition, the quantity of this type of GE corn found in Taco Bell tacos was only one percent?an amount too small to be of any consequence."
