关于转基因的英语作文

Recently, a debate about genetically modified foods between Fang Zhouzi and Cui Yongyuan has attracted many people’s eyes.

Fang appealed to people to come and enjoy genetically modified foods at micro-blogging which he thought is no harm towards human. Of course, this is not only his idea. It represents part of human who have great confidence and determination to make GM food become popular. Meanwhile, Cui’s question represents the worry and anxiety of the general public on GM, because no one can guarantee what will happen if people eat genetically modified foods for a long time. Such debate has both been in China and international. This time, the two celebrities put this issue in front of people again , I think we have to get more knowledge about it.

Firstly, genetically modified (gm) refers to the artificial separation(人工分离) and modified genes（修饰过的基因）imported into the purpose of the genome of the organism, so as to achieve the purpose of the modified organisms. Genetically modified (gm) is generally done by sexual reproduction. People often say "genetic engineering", "genetic engineering"（基因工程）, "genetic transformation"（遗传转化）are synonymous with genetically modified (gm). And then the genetically modified foods are produced in such way.

Then let’s look back to the history. In the early 1990s , the first genetically modified foods was produced in the United States that was a fresh tomato. Since then genetically modified foods become more and more popular. In March 2000, the cloned pigs were born. Followed, whether to eat genetically modified food becomes a debate both in Europe and America. According to the statistics , the U.S. Food and Drug Administration (食品和药物管理局) has identified 43 kinds of genetically modified varieties which makes The United States the largest country in genetically modified foods. In America, 60% of the processed foods contain genetically modified ingredients, including 90% of soybean, 50% of corn, and wheat are transgenic. There is not much difference between genetically modified foods and ordinary food, but genetically modified plants and animals have a distinct advantage, such like high-yield(高产) , insect resistance（抗虫）, anti-viral（抗病毒）and anti- herbicide（抗除草剂）. What I have to say is that with the application of transgenic technology the food shortage problem has been solved to some extent, the use of pesticide has been reduced, and the environmental pollution can also be avoided.

From the above, we may think the U.S. seems to advocate eating genetically modified foods. But it is undeniable that even in the United States, the debate around the genetically modified food has not been eliminated. Japan has even promoted organic foods vigorously to try to reduce genetically modified food. Europe has also adopted a strict market access system. Even in the United States where extremely reassure for genetically modified food, there are no direct transgenic technology for human staple food.

Although genetically modified foods have many advantages, there are also many studies showing that genetically modified foods have many flaws. In December 22, 2009,the Supreme Council of the French biotechnology (法国生物技术最高委员会) declared that cultivation of genetically modified maize is " more harm than good ."In the end of 2009, the U.S. Department of Health（美国卫生部）made a science paper that genetically modified foods can cause damage to internal organs. In May 2009, American Institute of Environmental Medicine (美国环境医学学会) issued a statement strongly to recommend
