While cloning provides many immediately obvious benefits, it also opens a Pandora box that will destroy social orders as we know it.Human society functions based on succession of generations and on each generation's DNA being different from the previous.With cloning, both of those will be changed forever.Cloning will allow those who can afford to produce fully transplantable organs to replace their aging organs and therefore possibly live to be hundreds of years old.Some may attempt to clone a complete copy of themselves and it means two generations will have exactly the same genetic composition.With line of generations blurred and unique genetic compositions across generations no longer a guarantee, human society as we know it will no longer be possible.And once this Pandora box is opened, it can never be closed again.
Cloning
Today’s technology develops so quickly that many impossible things become true; the cloning technology is the example. What is cloning? Cloning is a process used to create an exact copy of a mammal by using the complete genetic material of a regular body cell. Different from the common propagate, cloning need only one cell and without sex. In 1997, the great news shocked the whole world that the British scientists created a lamp named Dolly from a single cell, miraculously; the cell had been taken from the udder of adult sheep, which show the first cloning experiment was successful.
When the cloning technology improves so quickly, many scientists and doctors have different opinions, someone think it is good but someone think it is bad. Cloning can bring many benefits to the human, such as rejuvenation, helpful for Defective genes, Liver failure, Kidney failure and Leukemia. These disease are very different to cure, if we use the cloning technology we can change the Gene’s DNA order, so we can save lots of people.
But cloning still has some problems. The scientists found that the cloning animal’s Gene has a little different from the original animal. So the life will shorter than the real life. The fact proved that, the cloning sheep Dolly has died. It only has the half life of the common sheep.
In my own opinion I agree to clone the endangered animal and disagree with cloning human. Because I think the cloning technology should be respected. It really can bring us many benefits; further more it can develop the science of human. If clone the human, there will, however, be many problems, the population is the biggest problem. May be some people will use the cloning people to start the war. So I am against cloning human.
Also many countries disagree to clone people. The government makes the laws about cloning. There are laws against human cloning in Canada, Denmark, England, Norway, Spain, and the UK. Even in the USA, the government doesn’t allow to clone human. (Because in USA, the human right is higher than everything)
In the end, I think cloning is new technology, it should be accepted, how to look upon this technique, first we should know the advantages and disadvantages, then we should know the effect of cloning for human and the animal, third we will take the action: To advocate the animal cloning but be against with the human cloning.
Society
Increased food security for growing populations
If the low success rates can be improved (Dolly was only one success out of 276 tries), reproductive cloning can be used to develop efficient ways to reliably reproduce animals with special qualities. For example, drug-producing animals or animals that have been genetically altered to serve as models for studying human disease could be mass-produced.
Reproductive cloning also could be used to repopulate endangered animals or animals that are difficult to breed. In 2001, the first clone of an endangered wild animal was born, a wild ox called a gaur. The young gaur died from an infection about 48 hours after its birth. In 2001, scientists in Italy reported the successful cloning of a healthy baby mouflon, an endangered wild sheep. The cloned mouflon is living at a wildlife center in Sardinia. Other endangered species that are potential candidates for cloning include the African bongo antelope, the Sumatran tiger, and the giant panda. Cloning extinct animals presents a much greater challenge to scientists because the egg and the surrogate needed to create the cloned embryo would be of a species different from the clone.
Therapeutic cloning technology may some day be used in humans to produce whole organs from single cells or to produce healthy cells that can replace damaged cells in degenerative diseases such as Alzheimer's or Parkinson's. Much work still needs to be done before therapeutic cloning can become a realistic option for the treatment of disorders.
I want a clone of myself.Because if I cloned myself one day.I would let him do a lot of work for me .I would be relaxed .We could talk each other and help each other .After all, two heads are more clever than one . If he did something wrong , I would think of myself and avoid doing the wrong things.Above all , I find it interesting to have a company who is identical to me .

With the repid development of technology, clone comes to the world. It can duplicate creature, which means it can make contribution to the production. People can pay a little and get a lot in the end. However, it also has disavantages. I think as the development of the high-tech, people can use clone to copy humen beings. It’s so horrible for me to know that there is someone the same with me. But in general, clone has more advantages than disadvantages.
