克隆的好处与坏处

To clone or not to clone, is that the question?

Advanced technology has already pushed human being to edges, such as the production of weapons of mass destruction, the destruction of Ozone by Freon ,and the application of clone. The heated deabte over whether cloning technique should be used in human reproduc--

tion must be considered as a serious issue.

Clone, to a certain degree, is beneficial to mankind.Such disease as Parkinsons will possiblly be cured in the future in the hope of further applying of clone.However,the abuse of this technology will bring human being unthinkable destruction.

Since the declaration of the death of Dolly,we are more conscious of the

inefficient procedure of

clone.Acorrding to "Dolly's false legacy",the incidence of death among fetuses and offspring produced by cloning is much higher than it is through natural reproduction--roughly 10 times as high as normal before birth and 3 times as high after birth.And even you may argue that this technology will be perfected in the future, i don't see there is any point in whole--being cloning.

Many people consider this technology a promising one as to bring all human being to a new era in which all human reproduction will be accomplished by cloning.Thus scientists in some countries hxdye already started their great plan to clone human.But let's think, what is the practical value in doing so?You may tell me that it can bring hope for those couples unable to

hxdye children because they might choose to hxdye a copy of one of them rather than accept the gene intrusion from a doner.But imagine,if you hxdye a child owning the same apperance as yours or your husband's, will you accept it without any uncomfort?

Don't you think it is embarrassing?Or if this kind of human reproduction is allowed,terrorists may get hold of it and reproduce lots of "American Presidents".Don't you agree that these presidents might bring the world much more chaoes?Besides these terrible aspects,the cloning of whole--being may destroy the diversity of people of the globe.

Of course, there still remains much more disadvantages of the application of cloning reproduction of human being and animals. We should be extremely cautious of what we do and thus remember we will

sure be respondible for all the results created by ourselves

So how do u think about it?

In agriculture, people use "cloning" technology has fostered a large number of drought resistance, lodging resistance, pest resistance,

high-quality high-yielding varieties, greatly increased food production. In which China has entered the forefront of the world's most advanced.在农业方面，人们利用“克隆”技术培育出大量具有抗旱、抗倒伏、抗病虫害的优质高产品种，大大提高了粮食产量。在这方面中国已迈入世界最先进的前列。Cloning of the protected species, especially rare and endangered species in terms of a gospel, has great application prospect. From a biological point of view, cloning is also one of the most valuable.克隆技术对保护物种特别是珍稀、濒危物种来讲是一个福音，具有很大
