Introduction

Genetic Engineering Food Fan Ka Yi, Katie 6S(10) Genetically engineered food, also known as Genetically Modified or GM food, is food that has been altered at the genetic level to produce a better tasting, longer lasting, or more resistant product. Vegetables and other crops are the most common type of genetically engineered food. Corn, for example, has been altered to be naturally insect-resistant, while tomatoes have been modified to slow down the rotting process. A proposed benefit of GM foods is that they can potentially produce higher crop yields, which could help reduceing world hunger. As new species are altered to grow faster or more effectively, they can be used to feed poor nations or chosen for countries where crops may not normally prosper because of less than desirable environmental conditions. Some companies now claim to be producing crops that can help against certain diseases or provide specific nutrients, such as milk proteins and iron, which would otherwise not be available to some populations. ...read more.

However, every issue has two sides. Concerns have been aroused in the public about wheter GM foods could be harmful to health, and wheter their production would bring about adverse effects to the environment. A worrisome issue in GM foods is the ability of a food to trigger an allergy in humans. Some of the genes used in GM technology might be taken from a food that causes allergies in some people. Inserting that gene into another organism could cause the host organism to express that allergen as a trait. Alternately, a new allergen could be produced when genes are mixed across different species. Another potential downside to GM technology is that other organisms in the ecosystem could be harmed, which would lead to a lower level of biodiversity. By removing one pest that harms the crop, you could be removing a food source for an animal. ...read more.

Conclusion

Although supporters of GM foods stated that GM foods can help in sloving the problem of world hunger, I doubt about it. First of all, the "World hunger" is in fact cased by the uneven distrubution of the resources on earth and the problem is especially significant in thrid world conturies. I do believe the GM food can help raising the crop yeild but can the farmers in this countries affort the cost? Also, the technologies is still not mature engough. Lots of back-up is required if we put the technologies in pratice. Again, do these countries proceed the high technologies? This shows that the technology is in fact limited in the well developed countries. However, this countries do have already excess amount of food. The extra crop yield produced may finally become a trash in the landfill site.Therefore, I do not support the GM food. However, as time goes by, this techonogy may be well developed in the later time and can be affortable for third world countries and erased the worries of people. Therfore, we should keep an optimistic mind to this issue. ...read more.

    It is possible to end up creating harmful characteristics - such as toxins - unawares. This doesn't necessarily condemn GMOs but it proves the unpredictability of genetic manipulation. The establishment for GM foods is keen to cover up any findings, which may turn people against GM foods, (possibly due to the huge profits involved).

    Genetic engineering is an unpredictable and imprecise process.

There is concern that these could cause allergic reactions or other negative health effects.
