Advantages and disadvantages of cloning

Cloning technology will bring great benefits to mankind. For example, the ewe bred by British PPL company contains A- 1 antitrypsin for treating emphysema. The price of this goat's milk is $6,000 a liter. A ewe is like a pharmaceutical factory. What is the most effective and convenient way to breed this kind of sheep? The best way is to "clone". Similarly, the Dutch PHP company has bred cows that can secrete human lactoferrin, and the Israeli LAS company has bred sheep that can produce serum albumin. How can these high value-added livestock breed effectively? The answer is of course "cloning". A mare and a donkey can get an animal with a particularly strong heterosis-a mule, but mules can't reproduce. So, how does an excellent mule expand its reproduction? The best way is also "cloning". The giant panda in China is a national treasure, but its natural mating success rate is low and it is on the verge of extinction. How to save the large-scale cloning of this rare animal provides a practical way for human beings.

In addition, cloning animals plays an important role in studying cancer biology, immunology and human life span. Undeniably, the appearance of "cloned sheep" has also aroused many people's interest in "human cloning". For example, some people are considering whether they can clone an embryo from their own cells and freeze it before it takes shape. One day in the future, when something goes wrong with one of our own organs, we can take this organ out of the embryo for culture and then replace our diseased organs, which is to provide ourselves with "accessories" through cloning.

Human cloning has always been opposed by the overwhelming majority of people all over the world. First of all, it is difficult to identify the identity of clones, and their relationship with cloned people cannot be incorporated into the existing ethical system. Secondly, the process of human reproduction no longer needs the participation of both sexes, which will have an unbearable impact on the existing social relations and family structure. Third, human cloning technology may be abused and become a tool for terrorists. Fourth, in terms of biodiversity, a large number of clones with identical genetic structures may induce the widespread spread of new diseases, which is not conducive to human survival. Fifthly, human cloning may have psychological defects due to its special status, which may lead to new social problems.

The discussion about "human cloning" reminds people that scientific and technological progress is a mixed March. The more science and technology develop, the wider and deeper it penetrates into society, and the more likely it is to cause many ethical, moral and legal problems. I want to end this article with a sentence from J.D. Watson, a famous molecular biologist who won the Nobel Prize: "It can be expected that many biologists, especially those engaged in asexual reproduction research, will seriously consider its significance and start scientific discussions to educate people all over the world.
