Against cloning


After people have fully understood the mysteries of life, assembling and modifying life at will has become a matter of dreams that many people dream of. This is neither "the Arabian Nights" nor as simple as people think. However, something like this has happened. That is the cloning technique that ignores life. Its appearance has upset the world, and now a voice of justice is shouting: respect life, against cloning!

Life is the most respectable thing in the world. For thousands of years, people only know that it is unique. However, in November 1986, an unparalleled boar was born at the Agricultural Experiment Station in Beltsville, USA. The pig is about the same size as a normal pig, but with reddish-brown hair. A two-way squint eye squeezing on a wrinkled big face, swollen legs and legs, and severe arthritis. Originally, the researchers embedded a cow's growth hormone gene in the embryonic cells of the boar, instructing the boar's cells to grow the cow's growth hormone. The original intention of the researchers was to hope that the boars would be as big and strong as cattle, but they did not expect it to be counterproductive and frustrating. This genetic pig has no tempting value for humans. However, it has since announced to the world that the uniqueness of life is facing challenges.

Ten years later, in August 1996, another horrific event occurred in the biology community: the cloned sheep, "Dolly", came to the world at the Luslin Institute on the outskirts of Edinburgh, the capital of Scotland. It was not until February 27, 1997, that scientists at the Luslin Institute suddenly announced to the world that they had successfully cloned a sheep in the world using somatic cells first. The message came out and it was awesome. Some people cheered that this was an epoch-making breakthrough, and some people exclaimed that cloning would become a weapon to destroy humanity... In short, the little cloned sheep "Dolly" made the relatively quiet world of 1997 live for a while. When "Dolly" officially began to face the world, it has been seven months. At this time, "Dolly" was white, with slender and curved wool, a puffy nose, and a small red card with a distinctive identity on the right ear. It weighed 45 kilograms. Why is the little "Dolly"? Has it caused such a big sensation? It is the first mammal in the world to replicate using somatic cells. In the past, mammalian cloning technology only took the embryos out during the embryonic period and moved them into another egg, so that many twins could be produced. The "clone sheep" was different. As long as the living cells of the sheep were found, it is possible to copy a few sheep. , dozens of sheep...

"Clone pig" has, "clone sheep" has also, "copy people" will be far behind? Although technically, "replicating people" is not yet possible, but who can guarantee that one day in a small corner of the earth will make such a panic voice: the copying person "Dolly" has been born, The world has officially entered the era of cloning! However, human beings are not fully prepared for all aspects of psychology, physiology, and ethical systems. Once the "replicating people" come to the world, human beings will be helpless. Imagine: thousands of Hitler and bin Laden come out overnight, or themselves. Being "pirated", and... it goes without saying that life is no longer unique, life is no longer precious, and the world will become chaotic.

For this reason, biotechnology has been subject to legislative restrictions. In the United States, human cloning experiments have been banned, and countries such as Japan, the United Kingdom, and France have introduced similar regulations. Some countries even ban research on cloned animals. Of course, scientists themselves are not willing to be accused of being mad. Dr. Vimut, the father of Dolly, has repeatedly claimed: "We never thought about copying humans. 'Replicating people' is meaningless for research." In short, it’s hard to explore the meaning of the cloned sheep “Dolly”. It doesn’t seem to have much value, because its appearance is far from rising to the height of the milestone. For the entire 21st century biotechnology, this is just a A small prelude, although "Dolly" is so likable and world famous. However, one must see the fact that the only thing that makes Dolly becomes history.

People are seriously pondering the question: What will the world look like when biotechnology develops to the omnipotent day? When a copying person appears, life becomes a copy, but a clone is a replica and can never replace life. Life should be unique in the world. Cloning is the invention of the world, the contempt for life, and cloning is the weapon of destruction of mankind. We must do our best to respect life, against cloning, against the copy of life! Let life be the only and precious synonym.
