Tell me your opinion and basis on cloning.

1. Cloning Technology and Genetic Breeding

In agriculture, people have cultivated a large number of high-quality and high-yield varieties with drought resistance, lodging resistance and pest resistance by using "cloning" technology, which has greatly increased grain output. In this regard, China has entered the forefront of the world's most advanced.

2. Cloning technology and protection of endangered species

Cloning technology is the gospel of protecting species, especially rare and endangered species, and has great application prospects. From a biological point of view, this is also one of the most valuable places of cloning technology.

3. Cloning technology and medicine

At present, doctors can transplant almost all human organs and tissues. But as far as science and technology are concerned, rejection in organ transplantation is still the most troublesome thing. The reason of rejection is tissue incompatibility, which leads to poor compatibility. If the organs of "clones" are provided to "primitive people" for organ transplantation, there is no need to worry about rejection at all, because the genes and tissues of the two are compatible. The question is, is it legal to use "human cloning"? Is it economical?

Cloning technology can also be used to multiply valuable genes. For example, in medicine, it is through "cloning" technology that people produce insulin for treating diabetes, growth hormone for dwarfism patients to grow taller again, drynaria for resisting various viral infections, and so on.

Disadvantages of cloning technology

Theoretically, cloning technology is still immature; In practice, the success rate of cloning animals is still very low, some individuals show physiological or immune defects, and the disability rate of animals is quite high, accompanied by premature aging. In addition, the impact of cloning technology (especially the application of human embryos) on ethics and the strong public reaction to words also limit the application of cloning technology. However, the development of cloning technology in recent years shows that most countries in the world are not far behind, and no one has given up the research on cloning technology. The great theoretical significance and practical value of cloning technology lies in that it urges scientists to speed up their research and make the research and development of cloning technology reach a climax, thus better benefiting mankind.

About people: At present, cloning technology is developing very rapidly. Governments and people in different countries have different views on cloning technology. Cloning technology has shown broad application prospects, including the following four aspects: (1) cultivating excellent varieties and producing experimental animals; (2) producing transgenic animals; (3) producing human embryonic stem cells for cell and tissue replacement therapy; (4) reproduction of endangered animal species, preservation and dissemination of animal species resources. In the near future, cloning technology will be used to treat mental diseases such as diabetes, stroke, cancer, AIDS, heart disease and Parkinson's disease, and will greatly change the existing organ transplantation theory and treatment methods and bring good news to mankind. However, cloning technology also has some disadvantages. Theoretically, cloning technology is still immature; In practice, the success rate of cloning animals is still very low, some individuals show physiological or immune defects, and the disability rate of animals is quite high, accompanied by premature aging. In addition, the impact of cloning technology (especially the application of human embryos) on ethics and the strong public reaction to words also limit the application of cloning technology.

The great theoretical significance and practical value of cloning technology lies in that it urges scientists to speed up their research and make the research and development of cloning technology reach a climax, thus making it better serve mankind.

First, at the ecological level, gene replication caused by cloning technology will threaten the maintenance of gene diversity, and the evolution of organisms will go through a reverse process, that is, from complex to simple, which is extremely unfavorable to the survival of organisms. Secondly, at the cultural level, human cloning is a substitute and negation of natural reproduction, which breaks the self-discipline of biological evolution. It has a typical anti-natural nature, which is contrary to the rising basic cultural trend of advocating the unity of man and nature and returning to nature. Thirdly, on the philosophical level, after human beings achieve self-replication and self-reproduction through cloning technology, the relationship between body and mind may be disordered. The unrepeatable and irreplaceable personality rules of human beings have lost their uniqueness, natural basis and biological premise.

First of all, consanguineous birth constitutes the social structure and social relations. Why are almost all different countries and races opposed to human cloning? The reason is that it is another birth mode. Nowadays, the education of children from single-parent families has attracted much attention, that is, paying attention to an emotional cultivation problem. People's growth is completed in the state of sexual reproduction and parental care. It has been like this for thousands of years. How should society respond to the emergence of human cloning? What should be the relationship between cloned people and cloned people? Second, it is difficult to distinguish between identity and social rights. What if one day, 20 sons suddenly come to share your property, and their fingerprints and genes are the same? Do you have to engrave marks such as Kronchuan A000 1 and Kronchuan A0002 on your forehead like a license plate photo to identify it? Thirdly, people who support cloning have a point of view: to solve the problem of infertility, but the next generation cloned by an infertile person will still be infertile. You think you are excellent, and the people you can clone have the same blood type, looks, fingerprints and genes as you. In the research of human cloning, if something goes wrong, we can't dispose of defective clones at will like cloned animals, which is also a trouble. Therefore, in the current environment, not only the concept and system, but also the whole social structure do not know how to accept human cloning. "

Cloning technology will benefit mankind in the short term, but it will eventually bring disaster to mankind. And can reproduce the dead relatives to reflect grief. But if people are cloned by cloning technology, it will be a double disaster of human spirit and material, and human ethics will be destroyed spiritually. Cloning technology has unknown problems in the body, which may cause human genetic variation after several generations. More seriously, the grown-up transgenic people are also human beings and are protected by law. Their right to freely marry and fall in love will be protected by the Constitution, and their descendants will also blend in with the crowd. From a sociological point of view, after several generations,

Disadvantages: It is easy to be used by people with ulterior motives, causing extremely bad influence and violating ethics.

Cloning organs can bring hope to mankind in medicine,

But if you clone people:

1. will cause great panic to mankind, because those movies about terrible human cloning have demonized human cloning;

2. It will lead to a moral and ethical discussion, because grandma's clone may be smaller than her grandson;

3. It will cause another kind of discrimination, because it is said that unless there is gene mutation or other genes are introduced to become transgenic superman, clones will not be better than humans. Benefits: They can do things for human beings.

Disadvantages: If you clone smarter than humans, thoughtful humans will face extinction! Good thing. Bring the dead relatives back to life, and leave the rest alone.

Just extract a few paragraphs.
