Genetically modified organisms in agriculture essay
Genetically modified organism definition
Furthermore, the pharmaceutical industry has struggled for over a decade to develop oral medications based on RNA-mediated gene regulation without success, because it is extremely difficult to persuade the human body to absorb these molecules in a functional form because of the significant degradation that takes place in the gut. It is known that uncontrolled attacks of corn borers Ostrinia, Sesamia facilitate the growth of Fusarium moulds in corn grains leading to the accumulation of dangerous levels of fumonisins. With all that being said, GMO foods are one of the most frowned upon food sources in the world The willingness of consumers to pay a premium price for organic foods food not genetically modified has come at a time when genetically modified foods have come under scrutiny. Even if this company is taking steps to reduce the risks of GMO foods, it is apparent that GMOs are not ready to be produced commercially. Are GMOs, then, a risk or an opportunity to maintain the health of the environment? GMO foods may be a solution to combat the hunger crisis in these countries. The GMOs also affect the animals that are injected with these hormones. For instance, an excerpt from an article states how many countries require GMO labeling. However, the approval delays in the EU do pose a definitive and quantifiable risk for the safety of humans and the environment as they contribute to the perpetuation of older and less safe technologies, such as the use of chemical pesticides. So, while in large farms airplanes can be utilized to spray herbicides, certainly our farmers have to rely on manpower working directly in the field. Another example of the effect that GMOs have on the genetic makeup of humans is shown in an article by Better nutrition. However, more statistics support the fact that they are not only bad for the environment, but for human health
Catacora-Vargas, G. Darwin in his treatise on worms, plants are connected through reciprocal exchange of nutritional components with the microbial flora and fauna, both liable to be affected by all agricultural practices from the use of chemicals, soil management, water distribution, etc.
GM crops are currently submitted for risk assessment on a case-by-case basis using science-based risk assessment procedures, and it is acknowledged that as with all other technologies and, indeed, in all other areas of life we cannot expect zero risk.
The political implications on genetic engineering in the world of science and around the world are a controversial topic.
An example that provides evidence that the American public would like to see GMO labeling is provided by a photograph published by Consumer Reports. Finally, these GMOs are a danger to the natural genetic makeup, which puts humans in risk of genetic abnormalities in themselves and their children.
Genetically altered foods need to be removed from everyday agriculture because of the threat of health implications that they cause.
Genetically modified food essay conclusion
It increases the levels of the allergy causing proteins that found in the plant. Therefore the energetic burden of producing unnecessary detoxification enzymes and the genetic burden of possessing inefficient herbicide target enzymes can often make such plants less fit than their weedy and wild counterparts, naturally selecting against them in wild ecosystems where herbicides are not used, or in rotational agricultural ecosystems where the herbicide is rotated Gressel Buiatti: After the development by M. The active ingredient in this chemical is glyphosate, which prevents the plants from synthesizing the essential acids it needs. The consequences that technology of genetically modified organism could have on the environment is not known and a system as complex as genetic codes is not something to take lightly and should not be taken for granted without knowing all the facts. We will discuss throughout the rest of this paper the advantages and disadvantages of genetically modifying foods and crops. Consumers should be limiting the amount of genetically modified foods in their daily diet. Christou: GM food crops were first planted commercially in and in they were cultivated on million ha of land James In the first category, several new approaches have been developed to achieve pest resistance in addition to the current reliance on Bt genes, because Bt genes do not exist to counter the effects of all known pests. The impressive safety record of Bt crops is unprecedented, yet Bt crops in Europe are subject to draconian rules which even the EC has admitted make no sense Ramessar et al. Finally, the selective antibiotics are no longer used in a clinical setting, so even if resistance did jump to human pathogens, it would have no impact at the point of care. This technology dates back to the early s and in Deoxyribonucleic acid DNA was first discovered by Andrei Nikolaevitch Belozersky a Russian scientist. The question is can genetically modified foods be a good solution to help feed the growing population and what are the pros and cons associated with the social, ethical and scientific implications? Is an organism which has had its genetic makeup altered by removing part of its genetic makeup and inserting a modified gene from another organism or the mutation or deletion of the biome. Consequently it is then believed to be unethical by some.
Even if GMO labeling would be a detriment for the producer, it would benefit the customer immensely. The biological complexity of life is narrowed down to a single gene and shoot at with foreign substances that change a genetic trait of an animal or plant.
