Very good in medicine. Although human cloning has many disadvantages, it can also make many infertile people realize their dreams.
3. Now the scientific community divides cloning into therapeutic cloning and reproductive cloning. The former uses embryonic stem cells to clone human organs for medical research to solve the problem of insufficient donors for organ transplantation, which is supported by the international scientific and ethical circles, but there is a premise that the embryos used for therapeutic cloning cannot exceed the limit of pregnancy 14 days. As for reproductive cloning, that is, human cloning, on the whole, it violates the principles of bioethics, so the mainstream opinion of scientists is firmly opposed. UNESCO, the World Health Organization, the International Human Genome Ethics Committee and governments all expressed their opposition to reproductive cloning very clearly.
Modern science and technology is a double-edged sword, which will bring some negative effects while benefiting mankind. This raises a question for us: should modern science and technology, especially modern life science and technology, respect ethical principles or listen to ethical voices? Professor Shen pointed out: Now some scientists suggest that it should be done as long as it is scientifically possible. Actually, this is a wrong view. If technically we can create super life that seriously harms human beings, can we also create it? Some scientific lunatics are doing things that are harmful to mankind under the banner of "scientific freedom". Therefore, we should be wary of modern science and technology being used by some people with ulterior motives. In addition, the freedom of science and ethics cannot be opposed. The fact of the development of modern life science shows that there is no restraint in the regulation and guidance of ethics. Listening to the voice of ethics is conducive to the healthy and smooth development of science.
6. When the head of the company Clonaid, which claimed to have successfully manufactured the world's first cloned baby, announced the news to the world, the mass media expressed people's views on whether this technology would be misused in the future. Many people predict that this technology will lead to terrible consequences: arrogant hegemonists or dictators will use this technology to clone groups of ontologies in order to continue to control the developing world of science.
7. Cloning is absolutely good for human beings! 1984 The extinct spotted donkey was cloned successfully, which proved that cloning is not only good for human beings, but also good for animals! If people use this technology to clone more extinct animals, including cattle, wildebeests, pigeons and so on. Then this technology will make greater contributions to humans and animals.
