In recent years, as the technical agriculture is developing rapidly all over the world , the appearance of Genetically modified food is also to add the qualities to crop which the traditional breeding could.and we get a amount of benefits from it. However the genetically modified foods in the marketplace has resulted in a public debate, scientific discussion, and media coverage,which is come with the human health and a variety of ecologogical problems.There are , therefore ,.many arguments both for and against the issue. In my essay,I ¡®d like to discuss these effects in turn:

The main argument against is that whether GM food is benefit for us or not in generally

First of all, the power of genetic modification techniques raises the possibility of human health, environmental, and economic problems.

At the very beginning ,I think ,we should know what is GM food:¡°The techniques of modern genetics have made possible the direct manipulation of the genetic makeup of organisms ¡­Recombinant DNA technology thus has brought a new precision to the process of crop development¡±.

In addition, GM food also cause some financial problems. In most case, the benefit of the GM food does not belong to the farmers who plant the GM food on their own land. The government introduce the GM food to the farmers tohelp with the benefits of the low cost of it. And they have their own choice to the crop what they will plant. here i mean GM crops or non-GM crops. Actually, the farmers also want to produce the safe, high quality foods and make profit on it. As a result ,it has a big problem---cross contamination from the GM crops to Non-GM crops in the field. Once it occurred ,both trade are destroyed .On the other hand,in order to survive ,farmers have to plant what the people what to buy,and make a fair living,but there are so many public scepticism towards GM food,and the retailers drive down the price of it,which have a great effect on the farmers who plant GM food. these lead the farmer to lose in the competition instead of reducing the cost on farming which is claimed by many people. Therefore,it makes farmers much more poor than before ,and cause a serious financial problem for the poor .Here is an example to prove it:Many poor children often suffer from Vitamin A deficiency. that is because the poor families can not afford to grow more expensive crops and consume crops rich in Vitamin A,such as beans,pumpins,ivy gourds and leafy green vegetables .they eat little else besides rice.however ,a child would need to eat about 7kg aday(about 20 bowlfuls)to obtain the required of Vitamin A.

So in conclusion, although there are so many benefits of GM food , what we should consider , is the disadvantages of GM food when we decide to make GM food in the commercial trade. Because this is connecting not only human beings ,but also the environment where all the life are living in .

Although there have not been reported health problems linked to GMF, there are concerns that the possible transfer of new and unidentified proteins from one food to another may trigger allergic reactions to the altered food. Also, there has been no research regarding whether genetic engineering changes the nutritional content of food, nor have there been studies on the human safety of consuming genetically engineered foods. Although the biotechnology industry is quick to claim that no deaths or illnesses have been linked to genetically engineered food, how is it possible to be sure? Without labeling, there is no w
