In fact, the main reason why people can't accept human cloning experiments is the obstacle of traditional ethics. For thousands of years, human beings have been following the way of sexual reproduction, but human cloning is a product in the laboratory and a life created under human manipulation. Especially in the west, cloning "abandoning God to divide Adam and Eve" has been opposed by many religious organizations. Moreover, the relationship between clones is also contrary to the traditional ethical way of determining kinship by blood. All these make it impossible for clones to find a suitable place to live in traditional human ethics.

Science has always been a double-edged sword. However, whether a scientific and technological progress is really beneficial to human beings depends on how human beings treat and apply it, rather than choking on it just because it is temporarily unreasonable. Cloning technology may indeed be the same as atomic energy technology, which can not only benefit mankind, but also cause endless harm. But the essence of "fear of technology" is the fear of misuse of technology, not the fear of technology itself. Nowadays, all countries in the world have ambiguous attitudes towards human cloning. Last year, Britain passed a bill allowing the cloning of early human embryos with more than two-thirds of the votes, while in the United States, Germany and Australia, voices calling for relaxing restrictions on therapeutic cloning gradually sounded.

It can be said that which country has mastered the technology of human cloning first means that it has the advantage and initiative, and the country that started late may suffer unpredictable losses. Just as the United States first mastered atomic energy technology, although this technology showed its evil side from the beginning, later countries had to step up research and experiments in this field. From this point of view alone, it is also worth discussing to adopt a simple negative attitude towards human cloning experiments.

Introduction to human cloning:

Human cloning is no longer a dream in science fiction, but a reality. At present, three foreign organizations have officially announced that they will conduct human cloning experiments. Professor zavos of the University of Kentucky in the United States is working with an Italian expert named Antinori to plan to clone a human within two years. Because human cloning may bring complicated consequences, most countries with advanced biotechnology have adopted an attitude of explicit prohibition or strict restriction.

Meaning:

The first advantage of human cloning is that infertile patients who are in great pain because they can't have children can have their own children. Secondly, such cloning only uses the husband and wife's own sperm and eggs, avoiding the ethical and psychological shadow. In addition, cloning can also save endangered animals, maintain a reasonable population gender balance and protect the genetic genes of ethnic minorities. More importantly, human cloning can be used in research to compare and prove which is more important: human growth, environment and heredity.

Of course, there are some scientific facts in what you said, but they have not been completely confirmed by science. Some scientific experiments have come to the opposite conclusion. For example, Yang Xiang, a scientist from China, Connecticut, USA, successfully cloned 10 calf from the somatic cells of a cow aged 13. From DNA analysis, it was found that the telomeres of cloned cattle were much longer than those of their donors, and there was no difference between them and calves born naturally at the same age. This shows that the biological age of cloned cattle is exactly the same as that of cattle with natural sexual reproduction ability, which proves that cloned offspring have no premature aging.

Human cloning is a way and right of human reproduction. There are 70 million men in the world without any form of fertility. Human cloning is the last way of human reproduction. To overcome male infertility, cloning technology may be the last sword. Moreover, there are also many infertile people who ask scientists to use cloning technology to help them conceive children because they can't produce mature sperm. They also have the right to raise children and enjoy family happiness.

One kind is people who are not utilitarian and utilitarian. They just want to see if cloning can produce life and what kind of results it will produce. Another advantage of human cloning is that it can add a way of life to mankind. Today, drugs and environment have a great influence on human fertility, and in the future when human Y chromosome may disappear, human cloning will be a means of human survival.

Cloning human beings can help human beings to reproduce and cross a new process. It is reported that in 50 million years, men on earth will face extinction. If there are clones, all living things on the earth will not become extinct, as long as their genes are preserved.

Technical and moral issues:

Now cloning technology can only clone sheep, cattle and other animals. Although some scientists claim to have successfully cloned human beings, due to technical, moral and legal factors, there should be no real human cloning, even if possible, it is kept secret or not recognized by the mainstream media.

Although genes are thought to affect human behavior and cognition, the same genes do not mean that everything is the same; Basically, no one will deny that although a pair of twins are naturally "cloned" through the same DNA, they are not the same person, and they have their own experiences and incomplete personalities. But what seems normal is that the relationship between the cloned person and the cloned person is like twins who grew up in different places. Although they have the same DNA, they have different growing environments.

If a person copies a person with the same gene as himself as his "child" by cloning, it can be passed down from blood to blood. The ethical meaning of "carrying on the family line" is inconsistent with the traditional meaning, because it actually creates its own twin brothers or sisters. However, the current cloning technology is not very developed, which may produce clones with serious physical defects, and human cloning will also cause great opposition from public opinion.

Legal status:

Human cloning has the legal subject qualification of a natural person, which brings social chaos to the legal subject. Human cloning research is illegal, and human cloning researchers are suspected of intentional homicide and injury. The guardianship and custody rights of clones are not protected, and the rights of life and health and marriage personality of clones are not protected. The study of cloning is a temptation to commit further crimes, which violates the unchangeable ethics of human beings and is also a trap for human beings.

Disadvantages:

The disadvantages of human cloning are endless. The first is the technical imperfection. At present, many countries have successfully mastered animal cloning technology, but the success rate is only about 2%, and once the operation is wrong, the cloned animals are likely to be born with disabilities or even die. For example, Dolly, the world's first cloned sheep, was found premature. Assuming that there are clones, the life span of clones is generally lower than that of ordinary people, and their IQ and physical strength are also defective. Therefore, it is "very inhuman" to apply this extremely immature technology to humans. If human cloning has physical defects, human cloning will be blamed.
