Abstract


Genetically


modified


food


is


a


kind


of


food


that


people


apply


modern


molecular


biotechnology,transfer


some


biological


gene


to


other


species,


transform


the


genetic


material


of


living things. Through the application of biotechnology, a broad and significant increase of food


production can be happily seen at global agricultural production. This essay tells readers the basic


knowledge of the GMF and discusses the GMF in a critical GMF can help to solve


the food shortage problem,and it also can create new it brings us a lot of benefits,it


also leads to many safety problems. Firstly,The potential for GM foods to cause allergic reactions


is the most obvious health concern associated with these ly,although in developed


countries like American the law of the GMF is complicated,the new grain law have same more


rigorous


rules



in


China


and


other


developing



the


GMF


still


has


some


safety


problems


unseen.


we


argue


that


the


genetically


modified


technology


can


bring


more


advantage


and less disadvantage to us if it is used appropriate and r, it is essential to have a


critical attitude toward GMF until it is proved that the GMF is no harm to our essay can


help readers to know the GMF critically.



Key Words:




transgenic technology Genetically modified food food shortage;safety



Introduction


In biology class in high school,we first got in touch with transgenic,and we approximately


learned the basic transgenic can reform and make the use of the natural lives on the


ingredient of them by taking advantage of the research finds in life sciences,and can greatly follow


the will of its purest form,the term


or their products to modify human health and the human stingly, we learned the


fluorescent



s more,I can still clearly remember a fantastic ideas,that if we import the


chlorophyll gene into the dairy cattle,we might can make the caw in the sun and can get the milk.


Of course,that is a nice ,let



s scientifically learn the genetically modified food.


Biotechnology in one form or another has flourished since prehistoric times. When the first


human


beings


realized


that they


could


plant


their


own crops


and


breed


their


own


animals,


they


learned


to


use


biotechnology.


The


discovery


that


fruit


juices


fermented


into


wine,


or


that


milk


could be converted into cheese or yogurt, or that beer could be made by fermenting solutions of


malt and hops began the study of biotechnology. When the first bakers found that they could make


a soft, spongy bread rather than a firm, thin cracker, they were acting as fledgling biotechnologists.


The first animal breeders, realizing that different physical traits could be either magnified or lost


by mating appropriate pairs of animals, engaged in the manipulations of biotechnology.



Genetically


modified


food


is


a


kind


of


food


that


people


apply


modern


molecular


biotechnology,transfer


some


biological


gene


to


other


species,


transform


the


genetic


material


of


living


things,change


the


shape,


nutritional


quality,


consumer


quality


to


the


target


of



people's


needs.


The


GMF


can


help


to


solve


the


food


shortage


problem,and


it


also


can


create


new


it brings us a lot of benefits,it also leads to many safety problems. The potential


for GM foods to cause allergic reactions is the most obvious health concern associated with these


products,and


the


GMF


still


has


some


safety


problems



is


essential


to


treat


the


GMF


critically for ordinary people.



Advantages



We all know that the food shortage has been a serious problem around the Middle East and


many developing most important reason why We develop the GM is that it can help


to solve the food problem.


The most important contribution of the GMF


is that


it


can help to solve the food shortage



1983


when


the


first


time


human


got


transgenic


tobacco,


potato


by


using


recombinant DNA technology,the plant genetic engineering technology in the world has achieved


rapid development of transgenic plants for research and development,which has made a series of


remarkable


progress


and


has


nurtured


a


number


of


crops


with


disease-resistance,insecticide


resistance and even an incredible the help of them,we can feed another more than


millions of people,According to statistics,up to now ,no less than 1.6 billion people have benefits


from the area,our mother country China has made tremendous contributions to


the


world's



must


be


mentioned


is

cotton


and


hybrid


rice

Yuan


Longping.




The nutrition implications are also often cited as an obvious benefit for consumers, since the


bioengineering


could


create


plants


that


could


produce


more


nutritious


food. An


example


of


one


such product is


and iron. Developing countries that rely on rice as their major food source are often are the same


countries to suffer from high rates of childhood blindness and maternal anemia. Iron and vitamin


A have been shown to aid in the prevention and treatment of maternal anemia and blindness, so



Rice


might


help


to


reduce


the


rates


of


these


problems.

crops

1996,including


Soybeans,


cotton,


cereals


and


oilseed


crops now occupy 10% of global arable land. In 2010,81% of worldwide soybean, 64%


cotton, 29% and 23% of the grain is genetically modified oilseed y,29 countries grow


GM products all over the top three country with the largest area of cultivation is United
