Negative Effects of Genetically modified food Essay
Since the commence of life, nourishment is the first requirement for tout ensemble kind of alive. According to Chassy (2007), ahead of time gentles lived a hunter gatherer lifestyle and that around ten thousand years ago they started to transition into an agricultural lifestyle. Also they feed animals to their milk, burden and eggs. Later, several(prenominal) people enkindleed in agriculture in cast to survive and earn money. In todays world, technological developments and medical improvements resulted in higher life standards and world population become more than(prenominal) and more crowded.Lots of farmers and regimen companies emerged in order to becoming the of necessity of this growing population. Organic foods started to be insufficient for gentle organisms beca implement of the increasing population. As a result of this insufficiency, people seek different kind of foods with the tending of technological developments and they created agenttically circumscribed foods (GM foods). factortically change flash backs first appe bed commercially in the mid-1990s and today GM crops are grown commercially by 8. 25 million farmers on 200 million acres hand out finishedout 17 countries (Schmidt, 2005).Genetically limited foods or biotech foods can be described simply as foods derived from genetically modified organisms. These crop plants created for sympathetic or animal consumption using the latest molecular biota techniques. In his essay Genetically Modified Foods An Insight Raaz Maheshwari (2012) explains that Genetically modified foods are derived from genetically modified organisms. Genetically modified organisms substantiate had specialised changes introduced into their desoxyribonucleic acid by genetic engine room, using a process of each Cisgenesis or Transgenesis.These techniques are much more precise than Mutagenesis (mutation breeding) where an organism is uncovered to radiation or chemicals to create a non-specific but stable change. At the beginning, these crops have a bright and promising future. in time, safety of genetically modified foods was started to questioned and become a central issue driving the genetic engineering controversy today (Carman, 2004). Although round scientists claims that food derived from GM crops on the foodstuff does not have greater risk to charitable health than constitutional foods, there is a idespread research on several negative make of GM foods , including safety issues, economic concerns and environmental hazards. Recently, concerns about GM foods have raised by all environmental activists, religious organizations, public interest groups, professional associations, other scientists and presidential term officials. Also, they criticized potential hazards of GM food (Whitman, 2000). Specifically, this dissect posed the research question What are the general negative cause of genetically modified foods on earths ecology and homo health.As I mentioned earlier , humanity always requiring all kind of food. Although they meet their requires from hunting very beginning, agriculture is the main food resources when the first crop harvested. However food resources doesnt enough for humanity because of huge crowds, because of th? s reason people find a new give of food which named genetically modified foods or biotech foods. These foods derived from genetically modified organisms. Since mid-1900s genetically modified foods using our daily meal and from these time these foods always negotiated. in that respect is no exact consequences of these negotiations.However, there are carve up of negative personal kernels of genetically modified foods on earths ecology and human health such as allergetic diseases, poisoning both human and animals and cleansing beneficial insects. To begin with, lots of result of researches show us genetically modified foods are dangerous for natural life. According to Batalian(N. D. ) studies about GM products shown t hat these products can charge beneficial insects which most notably the monarch womanize larvae. He as well as verbalize there are other studies connect to the death of bees which are died during a contained trial with Monsantos Bt cotton, springtails and ladybird beetles.He state his same essay other studies about GM potatoes, spliced with DNA from the snowdrop plant and a viral parameter, show us these potatoes was deleterious to rats. Between the many insect pollinators of agricultural crops, honey bees are the vanquish known (OCallaghan, 2005). According to OCallaghan, cotton nectar is really amiable to them and produces useful honey, but if these cottons are genetically modified from engineers it can be harmful for bees why these cottons not natural and it includes different types of proteins and concentrations.Another effect of GM foods on natural life about gene delight to non-target species. Deborah B. Whitman verbalize his article Another concern is that crop plan ts engineered for weedkiller allowance and weeds will chump-breed, resulting in the transfer of the herbicide fortress genes from the crops into the weeds. These superweeds would thusly be herbicide tolerant as well. Other introduced genes whitethorn cross over into non-modified crops planted next to GM crops. Genetically modified foods set up the natural life where the people plant them.For fount GM trees or super-trees are being developed which can be sprayed from the air to kill literally all of surrounding life, except the GM trees (Batalian,N. D. ). He overly said these trees are often sterile and flowerless which is in contrast to rain forest teaming with life, or where a single tree can host thousands of rum species of insects, fungi, mammals and birds in an interconnected ecosphere. in that location are in any case terminator trees which has developed plants with the New Zealand Forest Research Agency to create still more lethal tree plantations.These super dea dly trees are look resembling super-trees, however these kind leaves exuding toxic chemicals to kill caterpillars and other surrounding insects(Batalian,N. D. ) worry the other cause of GM foods it also causes increasing numbers of yucky pests. According to Mellon (N. D. ), thither are signs that the most popular HT crops-those resistant to the herbicide glyphosate-will lose effectiveness as weeds become resistant to the herbicide. Scientists stockpile that BT crops, too, will succump to pests that evolve vindication to the BT toxins. fosterly, consumption of genetically modified foods from world effects their health negatively. First effect of GM foods on human health is allergenicity. According to Bakshi (N. D. ), food allergy is a very eventful health issue with the prevalence of immunoglobulin E antibody-mediated food allergies among adults being approximately 2% and nearly 5% in children. Bakshi also said consumption of genetically modified foods may trigger hypersens itised reaction. For example Bakshi said kiwi fruit not associated with any allergies in the 1960s.However , there are some people who are currently allergic to it the allergenic protein in the kiwi fruit was identified to be actinidin. Bakshi also said Genetically modified foods can introduce novel proteins into the food supply from organisms that are never consumed as foods. Some of those proteins could be allergenic. Second effects of GM foods on human health is antibiotic drug resistance. antibiotic drug resistance is the ability of an organism to be unaffected by the antibiotic, occurs by nature by evolution. According to Bakshi(N. D. , genetic engineering usually involves the use of genes for antibiotic resistance as selectable markers. These markers help to choose cells that consolidated foreign genes. There are concerns that these chosen genes might recombine with pathogenic bacteria in the environment or with naturally occurring bacteria in the gastrointestinal packag e of mammals who consume genetically modified food, contributing to the growing public health risk associated with antibiotic resistance for infections that cannot be treated with traditional antibiotics.It moldiness be true negative effects of GM foods because lots of European countries including Britain have refused to allow the Novartis Bt corn to be grown because the ampicillin resistance gene might be transferred from Bt corn to bacteria which these bacterias making a far less effective antibiotic against bacterial infections (Bakshi,N. D. ). Similarly Bakshi , enhs. umn. edu, said In recent years health professionals have become alarm by the increasing number of bacterial strains that are showing resistance to antibiotics. Bacteria develop resistance to antibiotics by creating antibiotic resistance genes through natural mutation. Third effect of GM foods on human health is cancer and degenerative diseases. According to article of Batalian (N. D. ) , lots of researches show u s GM foods or hormones which is used for increased milk production in cow causes breast and prostate cancer. Also he said some of Canadian researches prove that GM organism which injected rats mammals like humans, this organism dishonored thyroid cysts and internal organ. Besides , consuming GM foods causes autoimmune diseases, inflammation, arthritis and lymphoma(Batalian,N. D. ) Lastly, gene transfer from GM foods to body cells can cause disease.According to WHO(N. D. ), Gene transfer from GM foods to cells of the body or to bacteria in the gastrointestinal tract would cause concern if the transferred genetic material adversely affects human health. This would be particularly relevant if antibiotic resistance genes, used in creating GMOs, were to be transferred. In the light of all above mentioned studies, it could be said that scientist have not discovered the true researches consequences about genetically modified foods. They growth a non-natural nutrition, however they do not know their effects on human body and environment.It can be cause lots of bad diseases on human body and harm environment. Because it is dangerous for all kind of alive and natural systems, GM foods production processes should be controlled by new ministry and GM foods may be tested before marketing in markets. Those who are support GM foods said these foods have benefits on future hunger and they also support we all need these foods in future. According to Feuilherade (2011),humanity needs 40% more foods by the middle of the blow and GM foods is the only solution of this puffy problem.He also impart these foods are healthy for human body because if we change the DNAs of foods, lots of vitamins and drugs may added inside the foods. However, www. webmd. com(N. D. ), mentioned these foods are not natural and has no guarantees, also has some important risks, such as introducing allergens and toxins to food, accidental contamination between genetically modified and non-genetically m odified foods, antibiotic resistance and adversely changing the nutritive content of a crop.Scientists and governments always discuss this topic, however there is no exact result about harms or benefits of GM foods. Nobody do not know consequences of GM foods. Maybe after 50 years it will cause lots of diseases even will kill millions of people. There should be more and more researches about these foods and scientist and governments should give more importance, also all government which country interest growing GM foods, they should point-blank new ministry and specific research center of GM foods before trade in these product to innocence people.In conclusion, about GM foods, there are lots of researches and its effects on health and environment are not obvious. The scientist will move to improve these foods and sell them billions of people worldwide. With the support of governments and big bosses, poor and ignorant people buy these uncertain foods. Finally, I personally believ e that GM foods will cause lots of die onwards coming years, because of these reason these procedure should limited and controlled strictly by the government before selling. Also natural agriculture should be supported and use of organic food promoted.
