Genetically Modified Food †Pros & Cons Essay

never before in history has mankind so master entirey commanded its nourishment chain. Thousands of years ago, much of our species make the leap from a hunter-gatherer level of subsistence to an untaught society. With agriculture, late precisely surely rough another(prenominal) adaptions were made to fixs and animals hold and domesticated by us for the purpose of feeding ourselves. New specialized varieties with precise desirable traits slowly emerged with the advent of knowledge of hybridization, this butt against was greatly expedited. By today, much has changed in the demeanor we shape the solid feeds we prepare into our bodies.With upstart provender science has come the dawn of patrimonial modification. Food scientists working in bicycle-built-for-two with genetical engineers mint now isolate the genes for specific desirable traits from an entirely unrelated organism and splice them into an organism that we exact traditionally abs piece of groundsumedsay he llo to frankenfood. As a practice, genetic plan is the paying attention modification of a living organism done by essentially rewriting its DNA, thus fast-flyingener its genetic makeup in a dash that does not occur naturally (Domingo 535).The process of genetically modifying a plant entails inserting genes into plant cells by injecting vir spends which copy specialized DNA into the cells. The end goal is that specific traits deemed beneficial become newly expressed in the GMO (genetically modified organism). The movie Food Inc. , narrated by known authors Michael Pollan and Eric Schlosser (authors of The Omnivores Dilemma and Fast Food Nation, respectively), dedicates a large portion of condemnation to the modern use of genetically modified foodparticularly soybeansin American agriculture.The film hints at the various personal effects of using GM soybeans in agriculture, yet seems to be mainly focused on the economic electric shock the Monsanto GM soybean has on Midwestern farmers. It does at times indirectly suggest round doable wellness effects, though, at the time the movie was produced (2008only four years ago), not nearly as much was known ab fall out such ill bodily effects. The pro-GMO food camp often boasts of the feats of this distance age engineering in terms of productivity, efficiency, and wellness well-beings.Skeptics, on the other hand, see how this practice can wreak havoc on the environment, exploit the economically disenfranchised, and also pose many risks to human health. Here, by means of the scope of the critical, food-safety concerned (people identifying with the questions raised by authors Pollan and Schlosser), we pull up stakes explore these various cl accounts about human health as they pertain to the more than or less current technologies in frankenfood. One of the main purposes of genetically modifying crops is to im strengthen nutrition. in that respect is simply less food to go around in todays world.With the gr owing population and lessened crop yields due to drought (a likely implication of climate change), the price of wheat and lemon has tripled (Bourne) in recent years. Multitudes of people sire been disconfirmingly affected by this. The frightening shortage has prevented many of the worlds poorest citizens from getting the basic, nutritious food staple they need to survive. In some of the hardest walk out places, food riots have broken out in response to the startling scarcity. One of the clear potentially benefits of genetic modification in plants is its capability to lessen hunger worldwide.genetically modified crops could help annul the decline in yield growth by change magnitude drought tolerance, nitrogen efficiency, pest resistance, and photosynthesis rank (Crosson and Anderson). The challenge of putting enough food in nine billion mouths by 2050 is daunting (Bourne) with the increasing prevalence of food shortages. Genetic engineering of plants on a global scale whitet horn prove to be pivotal in averting a Malthusian catastrophe that is, necessary for the survivalor at least temporary sustenanceof humanity.Companies involved in the genetic modification of crops, such as Monsanto, believe that biotech ordain make it possible to double yields of incumbrance crops of corn, cotton, and soybeans by 2030 (Bourne). Introducing such crops to malnourished regions will potentially help alleviate the rising demand for food the world is currently facing. In Uganda, where gari, a potato-like tuber, is the primary food staple for the masses, a destructive plant virus struck the nation in the early 1990s.The pathogen devastated the cassava plants yield, damages many farmers livelihoods, led to near economic ruin, and, most importantly here, jeopardized health and nutrition of many thousands of native Ugandans. In some of the hardest hit areas of Sub-Saharan Africa, the cassava yields had been halved, all while the population of the continent continued to gro w at a precise fast pace. In terms of health, this disaster has led to, among other deleterious effects, widespread malnutrition and starvation.In 1999, scientists genetically engineered the plant to resist the devastating virus (Hand). Since then, there has been appreciable improvement in the situation. The recent political situation in Uganda (and many other famine-stricken, war-torn African nations), however, has prevented such ambitious implementations of genetically modified crops from reaching their full potential in helping to solve the global food crisis. In addition to alleviating this hunger crisis, the genetic modification of plants can foreseeably further advances in modern medicine.One truly practical use for genetic engineering is to turn bacteria into factories to make proteins and other compounds that are useful to humans. Researchers at Harvard University, for example, have late added a few genes to E. colis solitary circular chromosome, coaxing the organism to produce lycopene (Bacteria into Biotech Factories). In bacteria, this process allows for useful and vital products like insulin to be produced much more easily, and at lower costs. Likewise, genetic engineering of plants can be used to increase the concentration of beneficial botanical compounds used in medicine and health supplements.Although certainly not without risk, GMO technology has been around for almost two decades now, and has had much fewer negative implications on human beings than, for instance, newly developed cancer discussions. Yet trial and error for cancer treatment does not get the negative worldly concernity that the genetic modification of plants does, despite the fact that both aim at improving health for people who are otherwise very sick (be it cancer or starvation). In the United States, where opposition to frankenfood has steadily grown over the past decade, many scientists revere public suspicion regarding genetically engineered foods (within the countr y and abroad) could derail further research and development of them.Skeptical public thought whitethorn hinder the advancement of such crops that could potentially improve nutrition and overall health in regionssuch as famished Sub-Saharan Africathat could desperately use it. In addition to resoluteness the modern world-wide hunger epidemic, a more indirect yet very meaning(a) positive impact on human health owing to the implementation of GMOs in agriculture would be the lessening or boundary of mass deployment of harsh, toxic pesticides over acres upon acres of cropland.Pesticides have long been cited as producing many unwholesome effects with regards to human health. One of the largest indirect positive health implication of implementing GMOs in agricultural is the trim down use or end of pesticide application on food crops. First and foremost, pesticides ultimately cause propose organisms to develop resistance (Lu and Cosca) to their chemical components. In the end, this l eads to increasingly larger, more widespread use of pesticides and the need for more serious, more expensive, and more toxic pesticides to be applied to food crops.Studies have specifically demonstrated that agricultural workers exposed to pesticides on a routine basis developed higher incidence rates of cancers of the nervous, lymphatic and hematopoietic systems (Lu and Cosca). Furthermore, it has been documented that among infants whose mothers were exposed to routine pesticide use, there has been a significant association between in utero organophosphate (a very common agricultural pesticide) exposure and abnormal reflexes (Lu and Cosca). For this same commonly used pesticide, researchers have detect a severe and widespread incidence of neurotoxicity among the exposed (Lu and Cosca).Less severe yet nonetheless very sad effects of muscle pain, weakness change in taste eye pain, headaches, drowsiness tremors encumbrance in breathing, palpitations, throat irritation, and sweating (Lu and Cosca) have been linked to pesticide use as well. Many of these symptoms and conditions have been check to merely the level of pesticide levels found in soils (Lu and Cosca), and have not only affected agricultural workers, but also individuals living within relatively close proximity to intensely farmed areas.If (and/or possibly when) genetically modified food crops designed to resist pests naturally are introduced on a significant scale, the use of these chemical pesticides and their harmful effects on human health will inevitably be curtailed. scorn the growing yet relatively mild opposition to the genetic engineering of crops in the United States (as hostile to Europe), many scientists in the United States assertincluding former Greenpeace co-founder Patrick Moorethat genetic engineering isnt fundamentally variant from traditional breeding.Amidst objections raised by opponents concerning health risks, scientists such as Moore have questioned the honesty of the envir onmental third houses arguments on biotechnology and denounced such arguments as scare tactics (Lacy 195). To this groups way of thinking, the benefits of genetically modifying food in terms of health have so far outweighed the risks. As is unbowed in the scientific community, thought processs on GMOs vary widely among different groups and individuals.In the interviews I conducted, public opinion ranged from I think its good and yes, I think its safe from a health perspective to I dont like it, It is unethical, and it cant be too safe. much people were uneasy with its use than those who were not. One person even stated his belief that genetic modification can cause unnatural cell division and spread bacteria. From a scientific stand imply, this persons former claim is very plausible yet the latter is a little more unknown. scorn the likely benefits of increase yield and its effect on mitigating the world hunger crisis, as well as indirectly preventing many health problems assoc iated with the use of pesticides on non-genetically modified crops, there are also many valid health concerns surrounding this young biotechnology. Many researchers and experts have conveyed their legitimate apprehension over the potentially negative effects on health due to the consumption of genetically engineered agricultural products.Myriad studies have indeed found many potential health risks associated with consuming GM food products. Most of these con findings and opinions are not merely hypothetical and based on sociobiological models either rather, they are largely based on true scientific studies conducted in labs. In Food Inc. , author Michael Pollan is quick to point out that, contrary to the oft-cited plus of switching to genetically engineered crops that less harmful pesticides will be used, some GM crops are actually merely designed to better withstand pesticides.The film makes an example out of Monsantos Roundup Ready GM Soybean, which has been engineered to withsta nd much larger quantities of glyphosate, the highly toxic main chemical element in that particular pesticide (Food Inc. ). This fact directly contradicts the common claim that the implementation of genetically modified crops will lead to less pesticide use, at least in some very significant cases. given Monsantos mammoth market share within American agribusinesswhich produces much of the worlds food in our bread basketthis finding is all the more disturbing.More pesticide (the dangers of which being previously mentioned), not less, coupled with the finding that many GM foods have some common toxic effects (Dona and Arvanitoyannis 172), may compound health issues in the near futures. For good reason, this combination seems at least somewhat likely to prove to be quite a venomous cocktail. In addition to allowing for increased pesticide usage in certain circumstances, one of genetically engineered crops demonstrated direct detrimental effects on the body is the increased incidence o f allergenicity.Findings show that the introduction of novel proteins into foods may elicit potentially harmful immunologic responses, including supersensitized hypersensitivity (Dona and Arvanitoyannis 168). Due to the inherently complex biochemical nature of cultivated food crops, the introduction of a gene-expressing, nonallergenic protein may not always result in a product without allergenicity (Dona and Arvanitoyannis 168). That is, allergies to foods that were otherwise unknown or non-existent could arbitrarily crop up as a result of this unnatural exchange of proteins used to alter the core nature of a food crop.Generally speaking, many adverse microscopic and molecular effects of some GM foods in different organs of tissues have been reported (Domingo 537). Other than allergies, more serious health effects of GMOs include the potential that they may cause hepatic, pancreatic, renal, and reproductive effects and may alter hematological, biochemical, and immunological param eters (Dona and Arvanitoyannis 172). Through GMO consumption, humans are being exposed to an unprecedented come in of dangerous anti-nutrients such as phytoestrogens, glucinins, and phytic acid (Dona and Arvanitoyannis 165).These were proven to cause marked infertility in laboratory animals (sheep and cattle). Moreover, inflammation of the GI tract due to GM foods may lead after many years to cancer (Dona and Arvanitoyannis 169). Of utmost concern, however, is the disturbing finding that maternally ingested foreign DNA could be a potential mutagen for a developing fetus (Dona and Arvanitoyannis 170). Given these findings, it is clear not enough regulation is imposed and not enough research is made open and/or taken seriously by companies involved in the genetic modification of food crops. right off that this new leap in biotechnology has been available for over a decade and a half, scientists have had time to study the health implications of genetically engineered foods on the bod y more in-depth. The results the scientific community is convocation are startling. Pointing to a prior lack of extensive research on the subject, scientists underscore that the lack of leaven that GM food is unsafe cannot be interpreted as proof it is safe (Dona and Arvanitoyannis 164).We should also expire with the production of such genetically modified food as every single GM food through the food chain will eventually reach the consumer (Dona and Arvanitoyannis 164). In order to ensure food safety, many concerned researchers reaffirm the assertion that every genetically modified food crop containing a new marker gene should be tested for toxicity with long term studies, since GM food will consumed for a life time (Dona and Arvanitoyannis 167).Although the technology, as mentioned above, has been available to us for over fifteen years, this amount of time has not been sufficient enough to draw any such long-term conclusions. Until that is done, its implementation should be li mited to reasonable, unbiased experts assessments of what is necessary, or situations in which the likely pros would outweigh the likely cons. It is human nature to fear the unknown. As yet, genetically modified foods are still largely unknown to us.While these fears may lawfully stymie progress with regards to such a new, potential human health panacea, at the same time they also protects us as a species from over-ambitiously and haphazardly playing God, thus potentially opening a biological Pandoras Box of sorts. It can only help to push us further into solving our food dilemmas if we adopt a fundamentally cautious and critical mind-set regarding food safety, a la Food Inc.Because there are so many disconcerting findings regarding negative health effects on the human body with current GMO technology, it is imperative we continue to aggressively and objectively study it. And, given the very plausible positive effects of using GMOs in agriculture en massesuch as a well-nourished wo rld exposed to fewer carcinogenic and neurotoxic substancesthe key to harnessing this technology to our species benefit as a whole is a slow, careful, unbiased approach to its research, development, and testing.In any event, frankenfoods are charging their way into the modern world of agriculture and will almost certainly be a very significant hallmark of the near-futures era of food science, technology, and agriculture.Works Cited Bourne, Joel K.
