Download this Essay in word format. Genetically modified or genetically modified foods have been calling global attention for both their benefits and risks. The change is done by infusing a gene into the organisms from another or different organism. Most genetically modified foods are recently produced from plants.
Genetic manipulations can result in unanticipated harmful effects, and because genetically engineered foods are not tested sufficiently, this experiment not only jeopardizes the health of individuals, but could also lead to global food shortages and extensive ecological hazards.
It is impossible to predict the impact of genetic food, it is a matter of waiting for and observing future consequences. The cross-species transfers being made, such as between fish and tomatoes, would not happen in nature and may create new toxins, diseases, and weaknesses.
An example of a possible health detrimental effect is resistance to widely used antibiotics. A new type Genetic modification of crops essay maize is currently being produced in the UK. Maize is attacked by the corn borer mite, that chews through the stalks. We will write a custom essay sample on Genetic Modification Of Food Order now More Essay Examples on Genetically modified maize has been produced to be repellent to the mite.
The marker gene in the new maize is resistant to ampicllin, an antibiotic.
Scientists are concerned that when this maize is eaten, the gene will come in contact and be passed to bacteria living in the human gut. These bacteria would then be resistant to the antibiotic. There is only a slight chance of this occurring, but there is always a first time.
Transferring animal genes into plants also raises important ethical issues for vegetarians and religious groups. It may also involve animal experiments that are unacceptable to many people.
Once a genetically modified organism has been released into the environment it can reproduce, move and even mutate.
After its release, it cannot be recalled. Unlike chemical or nuclear contamination, genetic pollution is perpetual. It can never be reversed or cleaned up; genetic mistakes will be passed on to all future generations of a species. The huge areas of genetically identical crops will influence the evolution of local pests, plants, wildlife, and disrupt surrounding ecosystems.
There is no way of stoping genetically engineered plants from breeding with wild plants and contaminating them with foreign DNA strains. Pollen from genetically engineered crops can be transferred to cultivated and wild plants up to a mile away.
What would happen if the genes for insect and weed killer resistance, that have been introduced to crop plants, found their way into weeds?
If we allow the development of genetically modified food to continue we are consequently handing our lives over to the Biotech companies.
This practice would be prevented with genetically engineered crops under the terms of a license. There is also a possibility of companies selling sterile seeds. The companies developing genetically modified plants and animals wish to legally own these new life forms in order to protect their investments.
Supporters of genetic engineering say the gene splicing process is accurate and precise. In fact, the process of inserting genes is quite fortuitous and can damage normal genes. Many weaknesses in plants, animals, and humans have their foundations in minute flaws in the genetic code.Furthermore, many of the crops that are frequently genetically modified are subsidized by the U.S.
government so that if the market value falls below a certain price, the farmer will still receive a fixed rate on that crop (Cunningham, ). The Genetic Modification Of Today 's Plants Words | 4 Pages. The genetic modification of today’s plants. Good or Bad? In today’s society more and more commercial farms and food manufacturers are starting to grow and use genetically modified their crops in their products, is this a .

The huge areas of genetically identical crops will influence the evolution of local pests, plants, wildlife, and disrupt surrounding ecosystems.
The genetic modification of crops in the United States began in the s in California when scientists discovered recombinant DNA. Without going into too much detail, the recombination of DNA proceeds as follows: DNA responsible for a particular phenotype sought after is identified and isolated.
"Genetic Modification" just takes the process one stage further, allowing agricultural scientists to produce new varieties with specific required qualities. One of the main objectives in altering the genes of certain plants is to make them resistant to disease and to pests, and thus reduce the need for pesticides.
Published: Mon, 5 Dec Genetic modification of crops and food stuffs is one of the major controversial debates in the world.
There have been doubts on the safety of genetically modified foods especially in the area of human health and environmental degradation.
