In this blog post, we take a balanced look at the scientific possibilities that human cloning technology could bring, along with the ethical and social controversies that accompany it.
In 1997, Ian Wilmut and his fellow scientists succeeded in giving birth to Dolly, the cloned sheep. This event sent shockwaves through the scientific community and sparked a debate on human cloning. Human cloning technology, which had previously seemed possible only in science fiction, had emerged as a technology that could become a reality in the not-too-distant future. Of course, there is no doubt that as cloning technology advances and human cloning becomes a reality, it will bring many benefits to humanity. It will enable the development of genetic treatments for various diseases and offer hope to infertile couples wishing to have children. Furthermore, it could prevent children from suffering due to genetic disorders and be of great assistance in producing organs needed for transplants.
However, despite the many benefits that cloning technology can offer, the risks it poses cannot be ignored. Human cloning raises ethical, social, and legal issues, and these are not problems that humanity can easily resolve. Therefore, in this blog post, I would like to discuss why humanity should not yet pursue human cloning.
First, cloning can be viewed as a form of creating life. However, the case of Dolly has already clearly demonstrated that this process is not simple. Ian Wilmut produced 29 embryos from 277 oocytes; while three sheep were successfully born, ultimately only one cloned sheep survived. The fact that all three sheep born successfully were afflicted with large-fetus syndrome demonstrates that current cloning technology remains inefficient and risky. Furthermore, the possibility that these issues observed in animal cloning could apply equally to humans is a major cause for concern. If we recklessly apply this high-risk cloning technology to humans in pursuit of the infinite possibilities human cloning might bring, it could result in countless sacrifices and tragedies.
Furthermore, even if human cloning were to become technically perfect, it is doubtful whether human society could accept and adapt to the existence of cloned humans. Human cloning technology grants humans the ability to create another human being. This is a highly controversial issue ethically and conflicts with many religious beliefs. Various religions believe that only God can create humans, and based on this belief, human cloning technology is likely to be viewed as an evil technology. Consequently, the development of cloning technology—which could help people with genetic diseases and offer hope to infertile couples—may be delayed due to religious opposition.
Furthermore, there is a risk that human cloning technology could be misused for commercial or personal gain. Some people may attempt to create cloned humans for purposes such as organ transplants or clinical trials, which could lead to cloned humans being treated as mere commodities. Such commodification of humans would undermine human dignity in a manner similar to the slavery of the past. Of course, there may be legal attempts to prevent such acts, but history shows that laws alone cannot completely prevent all forms of misconduct. This could ultimately lead to serious social problems arising from the indiscriminate use of human cloning technology.
I am not arguing for a complete ban on human cloning research. However, the field of human cloning still carries many technical and social risks, and we must fully recognize these and approach the matter with caution. Considering that only about 20 years have passed since the first successful cloning of a mammal, I believe we still do not fully understand the limitations, side effects, and potential of cloning technology.
Therefore, I believe it is appropriate to proceed with research on human cloning only after further deepening research on cloning technology as a whole and ensuring its safety. Through this approach, we will be able to minimize the potential side effects of human cloning and maximize the benefits that the technology can bring.
