TOPIC: Scientists use living animal to carry our research. Some people think itis interesting, while some other people think it is cruel. What do you think?


Scientists use living animal to carry our research had been arousing a heated debate.Views on this issue vary from person to person.Some people think that animal in vivo experiment is not only unnecessary but also evil and curel. Other people think it is interesting and necessary. As far as I am concerned, I side with the latter one for the following three reasons.


Though it seems as if animal in vivo experiment is curel and even abnormal, it is do a short cut for scientits to find out effective ways to tackle with serious and unknow diseases. If scientists just research in the lab with out test in/on living animals, it is hard for us to even think about how many lifes will be take away by the the unknow diseases.


An equally import factor is lots of diseases are originate in animals. AIDS is a good example. If scientists want to discover the detail of this kind of diseases, living animal test is not only necessary, but also essential for they to find out the efficient way to prevent the diseases spread.


Last but not least, comparing with doing experiment on human beings directly, living animal test is a much safer and more effecient way to discover the best method to cured the patients.


From above analysis, it is not difficult for us to make a certain conclusion that using living animal to carry our research is do necessayr for our human beings. Althouht it is considered cruel outwordly, it is essential for scientists to fight against with diseases and save lifes.
