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
