Research Project Rough Draft:Futuristic Food

Picture biting into a nice big piece of corn on the cob. While it may taste good, there is much more to this piece of food then meets the eye. This particular corn cob has been modified genetically to resist pesticides. Furthermore, the adverse effects of these modifications have not been examined very close. There is no proof that the innocent action of eating corn could have ill effects on the corns consumer. Genetically modified crops are becoming an increasingly popular way to grow food. By modifying the DNA of certain crops, the crops take on new attributes such as the ability to resist pesticides or to grow bigger and faster. With increased popularity among farmers, the implications of genetically modifying food should be examined more closely, especially if genetically modified crops become the preferred choice of product for farmers. Although genetically modified crops have their upside, they are still questionable because there are potential health risks, potential environmental risks, and potential economic risks.
When scientists go in and change the DNA of a food product, they are changing what is going into the consumers body. While studies have been done on the potential health risks of genetically modified crops, the possible long term effects of eating these types of foods has not been determined. “Consumers are eating these foods without any apparent health effects, although some stakeholders caution that greater postmarket surveilence is needed to confirm this.”(Schmidt). The Food and Drug administration is required to do extensive testing to make sure that foods are safe for consumption but so far there is not substantial evidence that there is no possibility for adverse health effects rising from the consumption of genetically modified crops. What is more disturbing is these products are already being sold and consumed without consumer knowledge. “In 2002, The Royal Society itself concluded that GM technology might 'lead to unpredicted harmful changes in the nutritional nature of food'.” (Cook 133). Consumers should at least have a choice. Other potential health risks include the possibility that by eating genetically modified crops, the modifications could affect our own cells in unpredictable ways.The potential health risks of genetically modified crops should be examined before these products are consumed. Alternatives to eating genetically modified crops include eating regualr old fashioned crops. Other options include the eating of all organic crops to avoid these potential health risks.
Environmental concerns are another issue surrounding genetically modiefied crops. “There are a number of issues to consider, including development of resistance in insects against certain crop pesticides, transformation of crops into weeds, harmful effects on non-target organisms, gene flow, and altered uses of agrochemicals on transgenic crops.”(Kupier). Proponents of genetically modified food crops state that one of the advantages of using them is that they reduce the use of pesticides. In reality, the reduction of pesticide use is negligable and may actually result in more pesticide getting on the pesticide resistant crops. Because of this there is a possibility that the consumer might end up consuming crops that have been drenched in round up. Other envriornmental risk factors include the mutation of pests and weeds around the genetically modified crops. “indirect effects of glyphosphate in GRS could have effects on insects and wildlife.”(Cerdeira et Al.). The problems that result from each are the following. Weeds may become cross polinized with the modified crops and develop a resistance to the pesticides themselves. The result of this could have disastorous envrionmental effects. With the mutation these superweeds could choke out not only genetically modified crops, but could also affect non genetically modified crops in the area as well. The effects of this would result in the need for stronger pesticides to kill off the new super weeds. Another possible adverse affect of genetically modified crops is the mutation of pests that eat the crops. Like the new superweeds, pests may evolve to not be affected by the genically modified crops gene manipulation that makes them naturally immune to pests. With this mutation, once again, an increase in strength or use of pesticides would have to be achieved. Unfortuneatly for geneetically modified crops they may fuel what they attempt to prevent. Good alternatives to genetically modifying crops would be to put more money into developing safer more effective pedticides and herbacides. With modern technology chemical engineers may be able to invent pesticides and herbicides that have no impact on the environment at all while still efficiently doing their job.
Another issue brought up by growing genetically modified crops is the ethics behind the act of modifying the plant DNA all together. The idea of man playing god with plant and animal has always been subject to debate. The real ethical argument shouldn't be whether or not it is ok for scientists to modify crops and other food, but the ethical implications of corporations owning the rights to the specifically modified crops or livestock. When a corporation successfully modifies a crop, they then have the right to the patent of the genetically modified crop in question. When a corporation controls a patent, they control how much, when, where, and who can grow their product. They also have the right to take these privlages away. The implications of this could be devastating to global food sources. If corporations eventually control the majority of the food sources, then they ultimately control who can eat. This could be very dangerous in the sense that humanity will have to bend to the whim of whatever th corporations set for food standards. Even if genetically modified crops become the norm, measures must be set to limi the amount of control that corporate entities have over the food supply of the world.
Food is a necessity for human life. Genetically modified food is still really just beginning to become a realistic option for all food sources. More likely then not, genetically modified food will become a more prevelant force as a source of food. Researchers need to be sure that genetically modfied crops will not have any long term health effects on people, especially if genetically modified crops step up from being a minority food source to a majority food sources. Research should also be continued to be sure that irreversable environmental effects won't become a problem. The ethical implications of genetically modified crops must be closely examined and measures must be taken to ensure that food will remain available for all people in the world and not controlled by a select few. Genetically modified foods must be examined closer before they take a place a resonable source of food.
