Genetic engineering Essay Example for Free

Genetic engineering Essay Genetically modified foods (GM foods) have made for big talk in the public lately. Public interest groups have been actively protesting against GM foods for months. In response to the up swelling of public concern, the U. S. Food and Drug Administration (FDA) have held meetings to solicit public opinions and, begin the process of establishing a new regulatory procedure for government approval of GM foods. I would like to research and maybe, explain the reasons why I feel that GM foods are not humanitys solution to our food consumption problem. What are Genetically Modified Foods? Genetically modified foods are foods produced from organisms that have had specific changes introduced into their DNA using the methods of genetic engineering. These techniques have allowed for the introduction of new crop traits as well as a far greater control over a foods genetic structure than previously afforded by methods such as selective breeding and mutation breeding (Wikapedia. com). To date most genetic modification of foods have primarily focused on cash crops in high demand by farmers such as soybean, corn, canola, and cotton seed oil. These have been engineered for resistance to pathogens and herbicides and better nutrient profiles. GM livestock have also been experimentally developed, although as of November 2013 none are currently on the market. There are many reasons to not be a fan of GM foods but, before I explain the reasons not to consume GM foods, let me tell you some reasons why scientists and so-called, â€Å"experts†, are pushing to have developers and, manufacturers of GM foods make sure, that they are various advantages of consuming these foods, as well as, persuade the public to purchase these products. Are there advantages to GM Foods? One advantage to GM foods is that they help to control certain diseases that can cause people to have an allergic reaction to certain foods. With GM foods the DNA system is modified to eliminate the properties causing these allergies (http://www. buzzle. com/articles/genetically-modified-foods-pros-and-cons. html). Another advantage to GM foods is that they are said to be high in nutrients and contain more vitamins than traditionally grown food. They also claim to have a longer shelf life than traditionally grown food, which means less waste. Now that we have heard why developers, manufacturers, and scientists want GM foods massively produced, lets hear about some of the reasons why most of the population is not so accepting. Threats The biggest threat caused by genetically modified foods is that they can have harmful effects on the body (http://www. csa. com/discoveryguides/gmfood/overview. php). It is believed that consumption of these foods can cause the development of diseases which are immune to antibiotics. According to experts, people who consume these foods have high chances of developing cancer (http://www. csa. com/discoveryguides/gmfood/overview. php). Because these are new inventions on food, theres not much known about the long-term effects that genetically modified foods will have on humans. Foodstuffs made of genetically modified crops that are currently available (mainly maize, soybean, and oilseed rape) have been judged safe to eat, and the methods used to test them have been deemed appropriate. These conclusions represent the consensus of the scientific evidence surveyed by the International Council for Science (ICSU) and are consistent with the views of the World Health Organization (WHO). However, the lack of evidence of negative effects does not mean that new genetically modified foods are without risk. The possibility of long-term effects from genetically modified plants cannot be excluded and must be examined on a case-by-case basis. New techniques are being developed to address concerns, such as the possibility of the unintended transfer of antibiotic-resistance genes. Earlier, I mentioned an advantage to GM foods that allows them to be modified to eliminate properties within certain foods, so that people do not have an allergic reaction to them. My question is, â€Å"what in the world makes these developers think that we want to eat anything that has been modified†? Not to mention, knowing that the long-term effects are not certain if I consume one of these products. Thats not comfortably sitting on my stomach! Response These developers and, manufacturers claim that GM foods contain more vitamins and nutrients, along with a longer shelf life than traditional foods. The way the public sees it is the genetically modified anything, cannot be better for you than the real thing. Throughout my research, I have found that most of societys response to GM foods is, â€Å"why fix something thats not broken†? Most of society throws criticisms towards genetically modified foods, criticizing agribusinesses for pursuing profit without concern for potential hazards, and the government for failing to exercise adequate regulatory oversight (http://www. csa. com/discoveryguides/gmfood/overview. php). Concerns The most concerns about genetically modified foods falls into three categories: environmental hazards, human health risks, and economic concern. Environmental hazards are causes of unintended harm to other organisms. For example; the pollen blown around by the wind off of a GM plant, stands a chance of becoming involved with the milkweed plants that often grow near these crop fields. The concern is for the monarch butterfly, monarch butterflies eat milkweed plants and, if the butterflies eat the milkweed plant with the pollen from the GM plant on it, the butterflies then stand a chance of dying if they come in contact with this pollen. This could create a huge problem for the monarch butterflies extinction rate. Human health risks contain allergencity, which are allergies to things like peanuts and other foods. The possibility still remains that introducing a gene into a plant may create a new allergen that will cause someone to have an allergic reaction and, they could possibly die from that. Economic concern is the most talked about category out of all three. Things like, putting farmers out of business and bringing this product to the market is a costly process, as well as the tech companies wishing to turn a profit on their investment. Consumer advocates are worried that patenting new plants will raise the price of seed. When the prices of seed goes up, the farmers in third world countries cannot afford to purchase the seeds each year. No seeds means no crops for the farmers, no crops means no money. Conclusion Consumers may wish to select conventional foods on the basis of several criteria such as methods of production (e. g. organic or fair-trade food), religious principles (e. g. kosher food), or the presence of known allergens (e. g. groundnuts). Labeling of foods as genetically modified or non-genetically modified may enable consumer choice as to the process by which the food is produced. However, it conveys no information as to the content of the foods, and what risks or benefits may be associated with particular foods. More informative food labeling, explaining how food has been transformed and what the resulting changes in food composition are, could enable consumers to assess these risks and benefits (http://www. greenfacts. org). Genetically modified foods is a big deal in todays society, many people have a very strong opinion about GM foods. Many people are also unaware of what a genetically modified food is. Most people consume genetically modified foods on a daily bases and do not even realize it. Nor is the government obligated to inform you that you are consuming genetically modified foods. Throughout my research, I have found out why I feel that GM foods are not humanitys solution to our food consumption problem. Throughout my argument, I have tried to explain the good and, the bad things associated with genetically modified foods. I have come to the conclusion that genetically modified foods are not for me or my family. There are too many health issues and, risks that I am not willing to take because my familys health may lay in the balance.

Down Syndrome Essays -- essays research papers

Sometimes when meiosis ( the division of reproductive cells ) occurs, chromosomes may be lost, left behind, or too many may be passed on, resulting in the birth of a child with a genetic or congenital defect or disease. One of the most common of these genetic disorders is Down syndrome. This disorder takes its name from Dr. Langdon Down, who was the first to describe it formally, in 1866. Down syndrome is a condition marked by abnormal physical and mental development that is caused by a genetic defect. This genetic defect is caused by an extra chromosome. People born with Down syndrome have 47 chromosomes compared to the normal amount of 46, 23 chromosomes inherited from each parent. This extra chromosome originates more often in the mother's egg than the father's sperm. Chromosomes are individual, large DNA molecules in a cell nucleus. They contain the genes along with structures that hold the DNA and aid it in expressing heredity by orchestrating cellular operations. Down syndrome is one of the most common chromosomal abnormalities, occurring in about 1 out of 800 births. However, the frequency of the disorder varies greatly according to the age of the mother. For women in their twenties the rate is 1 in 2,000 but it rises steeply to 1 in 100 by the time a woman reaches 40. Down syndrome is usually recognized soon after birth because of characteristic facial features such as a flattened nose, upward slanting of the eyes, a large tongue that often protrudes from a smal...

Financing of Home Care Essay

In United States of America, health is an interesting topic in the society that does not only influence the well being of millions of Americans, but also influences the strength of Americas’ economy. This nation spends more on health care per person than any other nations. America is said to be having the highest infant mortality rates and a relatively low average lifespan. (Baer, 1989) For many families, lack of Health care is the source of vulnerability for the household’s economic status, as sickness or injury without health care can be a financial burden pushing families to poverty. According to the Census Bureau, the number of Americans having Private health coverage has fallen by one percent in the recent years. Home care is a term that is used to refer to the services that are usually provided in the home. They include giving patients professional services from physiotherapist, social workers and nurses. There is also the use of supplies, inclusion of therapies and incorporation of durable medical equipment. (Baer, 1989) The government has set the rules that have to be followed by each and every home care. In the home care, a range of services are therefore provided to the patients. The services include home making services, medication administration, blood transfusions, physical and occupational therapists among other services. Medicare on the other hand covers the home care services for the patients that have the following characteristics; †¢ They receive services from a Medicare †¢ They are under the physician’s care plan †¢ Those that are homebound †¢ Those that need nursing care that is very much skilled or physical therapy There are various ways through which homecare is financed. They include the following; †¢ Government funds †¢ Volunteers †¢ Commercial insurers †¢ Donations or charities †¢ Patients These are the major ways that home care systems are financed. Research reveals that systems are not for making profits. Looking at the various sources of finance for home care, there are different percentages of income that comes from each source. The government in most cases gives the highest percentage of income to the home care. This is approximately sixty percent of the total amount sourced. Donations then follow next with twenty percent. (Ehrenreich, 1970) Commercial insurers give approximately ten percent of the total amount of money that is used in the homecare systems. Patients are normally charged a small fee when they visit the home system and this amount to approximately five percent of the total revenue. There are normally volunteers who help out in providing some of the services free of charge and this helps to ease the burden of the costs that are incurred. Research reveals that there exists a very good relationship between the financiers and the homecare system. There is no one who ever wants to give his or her money without wanting to know how it has been used. Taking an example of the government as the main source of finance for homecare systems, it is always concerned with the faring on of the home care. (Ehrenreich, 1970) The government is normally very concerned with issues that affect home care especially in relation to the finances therein. The administrators of the home cares normally have the responsibility of giving account of how the finances have been spent in the home care. Looking at it from the administrator’s point of view, they normally wish that the government would do more than just send the finances to them but actually be more concerned with the whole project or the issues taking place in the home care system. To the administrators, the finances that are given by the government are not sufficient to cater for everything in the system and therefore planning becomes very hard in such a situation. The patients on the other hand are very grateful that the government decided to cater partly for their services given in the homecare because they don’t pay a lot of money. Research carried out in the year 2006 May in the United States amongst various patients reveal that patients come from different social status. There are those from affluent families, middle and then low income families. (Schaeffer, 2002) For the low income patients, the amount of funds that are given by the government are not enough because this compels the system administrators to charge them a fee which to them is a lot comparing it to their level of income. The patients who have middle income think that the government’s support is fair and they as patients can now afford it. For the affluent, they do not even feel the pinch of giving the little cash for getting services in the homecare but nevertheless acknowledge that the government is of great help. Donations and charities in form of funds given to the home care are given by organizations and individuals. There are various non-governmental organizations that give their donations to home care systems. According to the administrators in home care systems, donations and charities help a great deal in the smooth running of the systems. They concur that without the help of these non-governmental organizations, and then they could not have managed to do so many things in the home care systems. Patients also as stakeholders are grateful to the invaluable help of non-governmental organizations and individuals for this has enabled very many of them to access services that they could have otherwise not been able to. According to the administrators, the help given by no-governmental organizations though it helps it is not sufficient and therefore much still needs to be done. Looking at the relationship of the non-governmental organizations with the home care systems, one can say that there exists good relationship as the NGOs normally try to catch up on how the home cares are faring on. Research reveals that the relationship of the financier with the homecare is very important. A part from the financial help, there needs to be a mutual relationship between these two parties so that they can understand each other well. Looking at the provider or the financiers’ point of view, there is so much expectation from the home care system. From the government’s point of view, home cares expect so much from the government and there is the tendency to think that the government has got a lot of money lying idle which can be used in the home care system. According to the officials in the government of United States, the administrators have to know that the government is doing its best to see to it that these systems are run smoothly without financial strain. This is done so that every citizen benefits from these services and especially those from low income families per say. (Warren, 2005) Conclusion In home care, mostly the medical services are given in the home. In this case the patients are given professional services by nurses, social workers and home care assistants. These services include physiotherapy. Each and every home care system has to follow the rules that are set up by the government. (Strunk and Gabel, 2002) Home care systems are financed by various stakeholders. They include the following; the government, donations from individuals and from non-governmental organizations, small fee paid by the patients and from commercial insurers. Among these sources the government gives the highest percentage of finances to the home care systems. This is sixty percent of the total finances in the home care systems. According to the administrators in home cares, this amount is not sufficient to cater for all the needs in home cares. They say that the government needs to add more funds. According to the patients, the government is really playing a big role in enabling them to access these important services. (Strunk, and Gabel, 2002) To the low income patients, the funds are not enough and they should be increased so that they (patients) pay much lesser than what they are currently paying. The relationship that exists between financers and the home care systems is good. The administrators however say that the financiers need to be more concerned with all the activities that take place in the home care. Government officials say that home care administrators expect so much from them but they are doing their best to see to it that the home care systems do not strain financially at all.

TRUTH AND HONESTY IN THE MEDIA - 3414 Words

Truth and Honesty in the Media In a world surrounded by mass media, we depend on truthful and honest information to form accurate conceptions of current events and issues. Journalists, editors, producers and broadcasters should do their best to convey information that reflects the truth. Truth and the publics right to information should be the basic foundation for all journalists. One reason for the importance of truth in the media is that it demonstrates a respect for people as ends rather than as tools to be manipulated. In other words, it is not used to influence or control society but rather to benefit it. The public depends on the media to discover and report societal problems and issues that they themselves would never have the†¦show more content†¦Many will argue that regardless of the unethical use of the hidden camera, the end justifies the means. ABC Attorney, Andrew Hurwitz said hidden camera investigations, when used properly...serve good purposes. (Fishcer, 2002). In the case of ABC vs. Medic al Laboratory Management Consultants, the court claimed that the public interest was much more significant in this story and outweighed any privacy issues of the lab. There can be no doubt that information about a medical issue with potential life and death consequences affecting millions of women is plainly of public concern. (Tannenbaum, 2002). Supporters also argue that the personal lives of celebrities and public figures should become part of the media. Such situations have occurred in the life of Princess Diana who was constantly followed by the media. On the night of her death, she was followed by paparazzi in attempting to obtain a picture of the Princess and her new lover. Research published by the Broadcasting Standards Commission shows that the public believes celebrities should accept that all aspects of their life may be made public. (Hodgson, 2002). Many will argue that even the lives of private citizens should be made public in certain situations. In September 2002, Madelyne Toogood of Indiana was caught on a surveillance camera in Kohls department store parking lot, beating and slapping her 4-year-old daughter.Show MoreRelatedMozart Effect Field Research1740 Words   |  7 Pagesdevelopment in children.
