This problem of inadequate knowledge regarding a gene's complete function applies also to the use of genetic engineering in food production. Be it livestock or crops, the alteration of genes, for example to boost growth, could have side effects such as weakening resistance to a particular disease. The inserted gene could even code for something harmful to humans. These problems may not even be immediately noticed and are hard to stop once cattle have been bred, crops sown or distributed. A more controversial technique is the genetic alteration of gametes which causes a permanent change for the organism as well as for subsequent generations. Of course if the gene is corrected without further negative effects, the genetic disorder has been GENETIC ENGINEERING - The benefits and problems An extreme idea of the future of meat production (Man Made Life- Jeremy Cherfas) involves the engineering of entirely new forms of meat: "a vast organ culture of immortal muscle cells supplied with a steady stream of crude nutrients (perhaps from other engineered cells) and harvested by hacking off a slab". Personally the idea of this is extremely unappealing but it is clear that the efficiency of meat production would rocket as the result of such an advance. In addition really good custom written essays, the resources saved in such forms of meat production could be used elsewhere for human benefit. healthy person as well as advance preparation time for the transplant to minimise the risk of rejection. The main problem consists of the possible introduction of new diseases to humans. A particular retrovirus has been discovered which, harmless to pigs, has the potential to cause severe ill effects in humans. - 'World Book' Encyclopedia The solution is to change the antigenic properties of the pig tissue by genetically introducing human DNA that won't be rejected by the human immune system. Hence a breed of pigs containing human elements in their DNA was created. The obvious benefits would be a ready supply of organs not dependant on the death of a - Encarta encyclopedia (CD ROM) 2. Murphy, Tom. “The Arguments for and Against Genetically Modified (GM) Food.” N.p. 15 06 2009. Web. 22 Apr. 2013. <http://voices.yahoo.com/the-arguments-against-genetically-modified-2487771.html > Another advantage is the modification of genetic traits in human beings. Human genetic engineering science modifies human beings genotypes before birth. This process can be utilized to manipulate some traits in people. Genetic engineering can be employed to suppress negative traits while boosting positive ones. Positive genetic engineering is concerned with the enhancement of positive individual traits. This includes increasing human capacity or longevity. Conversely, negative genetic engineering is concerned with the quelling of negative human traits such as some genetic diseases. As seen in the discussion, genetic engineering is beneficial but it manipulates the natural. It alters what is natural to produce completely new “creatures”. Human beings ought to consider the pros and cons of genetic engineering before using it. Genetic engineering can in the modification of human DNA. If discovered assignment writing service australia, genes responsible for particular human qualities can be inserted into the genotypes of other humans by artificial means. This brings about desirable functional and structural changes in such individuals. Genetic engineering entails manipulating an organism’s gene indirectly using techniques such as molecular cloning to alter the nature and structure of genes. It can change an organism’s characteristics through DNA manipulation. Human beings ought to consider the pros and cons of genetic engineering before using it. In my opinion, this is more than just a scientific issue because to me it sounds like an interference with the work of nature and creation. The environment I believe is at serious risk, more so when scientists take out genes from animals. They are living essay on the holocaust, breathing things with a mind, instincts, and impulses. This is mind boggling because no one really knows what will happen to something that’s modified and given new characteristics it is not used to. The environment had withstood a lot but nothing to the degree of changing the genetic make up of a species that have existed for years.
In a world where the land mass cannot be modified to accommodate more, increasing population and more people demanding more food for less money it may be difficult for some to understand why biotechnology is considered to be something that will destroy the earth. It is a very controversial topic that is growing in interest to all with pros and cons that both sides must acknowledge. Here you will find also different types of samples such as persuasive / argumentative, critical, descriptive, narrative, cause and effect, exploratory, expository, compare and contrast, 5-paragraph, classification, definition and even scholarship / admission essay papers for your application. All academic essays are formatted in any citation style: APA, MLA, Turabian and Harvard format. Third, GM crops are being forced on the whole world by biotechnology multi-nationals seeking monopolies for their products. After Green Revolution, agriculture in many countries reorganized their own farming industry to increase productivity and tried to change to be the mechanization of agriculture and depended gradually on the petrochemical industry. It is a true agricultural output has risen, but agriculture is subjugated to Multi-nationals rule forever. By having a lot of output, consumers and farmers get a profit, but companies such as Monsanto, Novartis and Aventis get a lot of profits. Their rules of food have been far more serious. In Monsanto case, the company developed herbicide Round up, Roundup Ready Soybeans which only work on Round up and have made unreasonable profits by them. So, when farmers buy their products, they should buy both of them. Moreover, Roundup Ready Soybeans use 2-5 times more herbicides than non-GM plants. This way, multi-naturals have encroached on the whole world food markets. When all food in the world becomes GM foods or their products, we could not imagine what will happen to human from a point of view of the food problem. People who advocate GM crops and some people affirm that it is an obvious fact to be guaranteed to solve the food problem because of improvement productivity. However, the fact is definitely not true. There is no relationship between the prevalence of hunger in a given country and its population (Lappe, 1998). The real reason of hunger and famine is the public are poverty, unequal division and limited foods in developing countries. The food problem is not about how yields increase, it is related to the fair distribution of food.
