克隆的好处与害处

好处

论据一：美国，瑞士等国已经能利用克隆技术培植的人体皮肤进展植皮手术。曾经有一位美国妇女在一次煤气炉意外爆炸中受伤，75%的体表被严峻烧伤。医生取下一小块未遭损坏的皮肤，送到一家生化科技公司。一个月以后，该公司利用先进的克隆技术，培植出了一大块健康的新皮肤，使患者迅速得以痊愈。这一全新技术防止了异体植皮可能出现的排异反响，给人类带来了福音。科学家们预言，在不久的今后，他们还将借助克隆技术制造出人的耳朵、软骨、肝脏，甚至心脏，动脉等人体组织和器官，供医院临床使用。

论据二：在繁衍许多有价值的基因方面，克隆技术是也有大用武之地。例如，在基因工程操作中，科学家们为了让细菌等微生物“消费”知名贵的药品，如有希望使侏儒症患者重新长高的生长激素以及能抗多种病毒感染的干扰素等等，分别将一些相应的人体基因转移到不同的微生物细胞中，再设法使这些微生物细胞大量繁衍。与此同时，人体基因数目也随着微生物的繁衍而增加。在人体基应被大量克隆时，微生物也随之大量的“消费”出人们所需要的名贵药品了。论据三：在根底生命科学方面，克隆技术使得对基因功能研究从以往只能在小鼠身上进展，到如今在多种动物身上均可得到实现，这有利于更加明晰地提示基因功能和生命本质；克隆技术提供了研究哺乳动物细胞发育全能型以及核质关系最有效的手段之一；克隆技术能够克隆出各种濒临珍稀动物，从而提供基因型完全一致的实验动物，这有利于找到疾病的有效治疗方法，提示发病的机制，并有助于抗衰老及其机制的研究。

总结（好处）：

一、无排挤反响的器官移植。

二、濒危物种保护。

害处：

一、克隆技术如今还不成熟，克隆人可能有特别多先天分生理缺陷。

二、克隆人的身份难以认定，他们与被克隆者之间的关系无法纳入现有的伦理体系。

三、人类繁衍后代的过程不需要两性共同参与，将对现有的社会关系、家庭构造造成难以承受的宏大冲击。

四、克隆技术有可能被滥用，成为恐惧分子的工具。

五、从生物多样性上来说，大量基因构造完全一样的克隆人，可能诱发新型疾病的广泛传播，对人类的生存不利。

六、克隆人可能因本人的特别身份而产生心理缺陷，构成新的社会征询题。 从道德价值的角度：

一、从社会伦理角度，克隆人是对人类开展的一种过强的干涉，可能阻碍人种的自然构成和自然开展。

二、从家庭伦理角度，会加剧家庭多元化倾向，瓦解正常的人伦秩序，改变人的亲系关系，丧失根本的归属感。

三、从性伦理学角度，完全改变了人类自然的、基于性爱的生育方式，使人口的产生与性爱别离，破坏人类的感情。

四、从生命伦理学角度，破坏了人拥有独特基因的权利，有可能导致人种的退化，还会使正常的生与死的观念发生动摇。

从生态层面：

克隆技术导致的基因复制，会威胁基因多样性的保持，生物的演化将出现一个逆向的颠倒过程，即由复杂走向简单，这对生物的生存是极为不利的。 从文化层面：

克隆人是对自然生殖的替代和否认，打破了生物演进的自律性，带有典型的反自然性质。与当今正在兴起的祟尚天人合一、回归自然的根本文化趋向相悖。 从哲学层面：

通过克隆技术实现人的自我复制和自我再现之后，可能导致人的身心关系的紊乱。人的不可重复性和不可替代性的个性规定因大量复制而丧失了唯一性，丧失了自我及其个性特征的自然根底和生物学前提。

篇二：克隆技术利弊英语

TheCloningTechnology

With the development of science and technology, our side appeared a lot of new things，such as clone，The scientific invention of clone has become a hot topic among people，especially among the young and heated debates are right on their way.

Now the cloning scientific has been used for many years to produce plants, it has brought us a lot of benefits but has created some serious problems as well.

The benefit of cloning is cloning human organs or body parts , such as that if a parson in a traffic accident lost his arm or leg ,or someone get a serious heart disease and face danger ,he need a new body parts replace ,At this time we can use cloning technology copy a new parts of body to replace ,in the this way can be ensure that someone continue to live ,so that the clone is benefit for us .

Everything has two sides and cloning is not an exception，it has both advantages and disadvantages. On the contrary，most people are against of cloning technology been used in our life, One of the biggest reason is that human cloning technology will break the gender balance，it will be bring up a great chaos.

As far as I think cloning technology is more much disadvantage for human being ,we should very careful to use it, I believe that only in this way our life will be more beautiful

篇三：英语作文(克隆利弊)

Will cloning be promoted or prohibited?

With word that scientists succeeded in cloning an adult mammal being spread in air, it turns to a heated discussion that whether cloning will bring fortunes or misfortunes to human society.

Many believe that the advantages of cloning weigh over its disadvantages. They insist that cloning can save the rare wild lives from dying out. Also, cloning can throw light on some serious diseases. Maybe it can save people’s lives.

While others argue that world with cloning is disastrous. They hold the view that cloning will destroy the ecological balance and an increasing number of transplants will be sold illegally. From their view of claim, cloning will make our world in chaos.

As for me, I stick to the opinion that every coin has two sides. That’s to say, anything new-born will undoubtedly bring fortunes and misfortunes to the world. Therefore, it is we human beings that depend its trend. We should make full use of its fortunes and carefully avoid its misfortunes. In that way, I believe the future of cloning will be bright.
