Oppose (disagree with cloning):
A few days ago, an American scientist revealed to the outside world that scientists from many countries are preparing to jointly clone human beings, and ten infertile couples have signed up for the experiment.
Scientists plan to combine ordinary male cells or main cells with a female egg, and the genetic information stored in the female egg will be eliminated in advance. The embryo formed by cell division should only carry all the genetic information of this man, and finally the embryo should be transplanted into the female uterus. Of course, a couple can also clone women if they want.
Scientists further said that in the practice of animal cloning, it usually takes hundreds of failures to create a living embryo, and the key to the success of human cloning lies in the stability of genetic information. The experiment will be conducted in a Mediterranean city.
Before the birth of human cloning, people had better not jump to conclusions. It is necessary for us to correct the wrong conclusions in our minds. The following lists several wrong views about human cloning, followed by correct comments.
1. The cloned human is not normal.
No matter how cloning technology develops and how clones are produced, they are all human beings, essentially brothers and sisters of different ages, which makes it difficult for people to deal with the ethical relationship of clones.
2. It is God's duty to clone and create people.
Cloning does not create life, but creates life from present life.
3. Cloning is not a natural process
Cloning takes advantage of naturally occurring reproductive processes. Although some people say that cloning is not a natural form of fertility, it can be said that it is a fertility process with the help of artificial environment.
4. Clones have no brains.
Clones have the same feelings and feelings as normal people, but they have different feelings. A well-known example is the cloning of Hitler. Will he create a massacre? Although a person's personality is partly determined by genes and is born, the external environment plays a greater role in the formation of a person's personality. If the cloned Hitler lived in present-day America, the whole world would be in a stable and prosperous state. This Hitler is different from Hitler who lived in post-war Germany and was full of hatred and ruins.
5. Cells in any part of the body can be used for cloning.
No, the researchers are not sure about the details. They think that a kind of cell called stem cell is easier to make. This kind of cells all over the body can produce many other cells, even in hair.
6. Everyone can have a clone.
Although cloning is considered to be a good way to treat infertility in the future, basically, cloning is made by parents, and not someone can clone it casually. Many people think that human cloning can do a lot of work like slaves, but don't forget that human cloning has the same rights and obligations as human beings.
7. If a vegetative person and other unconscious people are cloned, the cloned organs can be provided to human beings.
On the one hand, it is immoral to clone unconscious people, on the other hand, it must be admitted that cloning unconscious people requires more keen knowledge and technology. Consciousness does not have the characteristics that can be taken away casually through genes, and there is no independent DNA to determine whether consciousness exists or not. Besides, it is difficult to prove that a clone has no self-awareness. Even a vegetable, we have to admit that he is conscious inside.
Some researchers have theoretically confirmed that only some human organs can be cloned. Scientists believe that the cloned organs have the same genes as their mothers, so there will be less rejection during organ transplantation.
8. Great historical figures and heroes can be reborn
At present, the technology of human cloning is nuclear transfer, which requires the combination of two living cells: eggs and cells containing DNA to be copied, and even frozen dead people. At present, it is unlikely that cloning dead people will succeed in the future. Even if these people are cloned, as we mentioned earlier, their personality development is inseparable from their external environment, so the cloned Hitler will not be like the devil Hitler in World War II, and the cloned Einstein will probably not become a great physicist.
9. putting a person's nucleus into a sheep's egg will have a miracle.
This is impossible, because when the genetic material put into the egg begins to divide, it works according to the instructions given by protein in the egg. If the egg and DNA come from different substances, the related instructions can't cooperate, just as people can't understand the language of sheep.
10. People can be cloned endlessly.
Dolly the cloned sheep was born, but its chromosome tells us that it was several years old when it left its mother.
Scientists at the Roslin Institute in Scotland have carefully studied Dolly's chromosomes and found that telomeres at the ends of chromosomes are shorter than those of ordinary sheep of the same age. Scientists believe that telomeres are the main factor that determines cell senescence. The shorter telomeres are, the closer cells are to death. Shortening telomeres may indicate that the genetic blueprint will age over time, and it is impossible to clone an animal endlessly.
No matter how many people object, maybe we should start to learn to say hello to clones.
Italian and American scientists have joined hands to study human cloning. With the support of a country and volunteers, there is 5% confidence that a clone with unknown name will be born.
1996, a lamb named Dolly caused a sensation in the world. Since then, people have a hunch: will we follow the sheep? Almost everyone is uneasy about the idea that human beings are in science.
There is no room in front of me. The active opposition did not resist the scientist's insistence. Since it is possible in theory, it is also possible in fact. Nothing can really stop science. However, despite my rich imagination, I still don't know where mankind will go. Since the clones are coming to see us, let's get ready.
Regardless of the intention, cloning reduces human life to a commodity, which is created and destroyed for civilization. No matter what the purpose of human cloning is, this action itself will turn human life into a commodity, a commodity that is only made and destroyed for someone's convenience.
