Genetically modified organism - DNA Essay Example for Free

genetically change organism DNA Essay1. Introduction Genetically modified pabulums ar foods derived from genetically modified organisms (GMOS). GMOS have had particular turns led to their DNA by genetic engineering techniques. In fact,GM foods are already get a part of our life. (Maessen, 1997) The 2010 estimate, the most recent, says that 925 million people were undernourished in 2010 (FAO 2010). There are clearly some very real issues that need to be resolved. The purpose of this paper is to discuss whether GM foods can solve the problem of world hungry . It covers two advantages of GM food which are increasing deed and effects of environment defendion,finally it will cover a disadvantage for human health. 2 . Advantages 2. 1 Increase in food production GM food should be consider as a solution to slove world hunger as it unveils much higher yield than conventional crops. Firstly,Crops are genetically modified in order to make them pest-resistant, drought-resistant, high er yield per acre, faster maturing, or some other improvement over natural crops.They are likely to be safer than ordinary crops since they dont have chemical pesticide on them , they are more likely to be picked and sent to market at their peak of ripeness, and are likely to proceed longer once you have them home in refrigerators. Its helping to resolve the worlds hungry problem. 2. 2 Advantages for environment protection One effect of GM foods is to protect environment. Genes could also be manipulated in trees, for example to absorb more CO2 and reduce the threat of global warming.Genetic Engineering could increase genetic diversity, and produce more variant alleles which could also be crossed over and implanted into other species. (Friends of Earth,2003) 3. Disadvantages of GM foods potential negative human health There are also critics objected to potential negative human health. As it has a Genetic engineering may actually counteract the processes of nature by reducing the und erground of the species to environmental extremes and diseases by creating ideal traits. Furthermore, new viruses would be encouraged to mutate into more dangerous, virulent forms that would be unstoppable.Even more horrifying is the possibility that genetically engineered products have the capability of being toxic and threatening to human and animal health. (Royal Society. 2002)Some scientists believe that introducing genetically modified genes may have an irreversible effect with consequences except unknown. (Food Standards Agency. 2002. ) 4. Conclusion In conclusion,this paper discussed the effects of GM foods. Therefore, according to these passage that the genetically modified technology can bring more advantage and slight disadvantage to us. It becomes a tendency to eat genetically modified foods.So we just be at ease to eat unless the productions are counterfeit and modest and it is not qualified by the standard department and the GM foods almost can solve food crisis.
