Scientists use living animal to carry out research. Some people think it is interesting, while some other people think it is cruel. What is your opinion?
You should write at least 250 words.
You should use your own ideas, knowledge and experience and support your arguments with examples and relevant evidence.
Model Answer :
Concerning the issue whether scientists should use living animals for scientific research, people hold different views. Some people claim that it is cruel, while some other people argue that it is beneficial to the development of science. As far as I am concerned, I am in favour of carrying out experiments on animals.
Firstly, scientists can do initial experiments on animals to test the effect of a new medicine. Scientists have achieved so many milestones on the way to medical development. But they can not find any effective treatment for some diseases yet, like cancer and AIDS, which are fatal to people’s health. Through experiments on animals, scientists can not only understand the pathology of some diseases but also try the effect of medicine and find the most effective treatment for these diseases, making a great breakthrough in the field of medicine.
Secondly, using living animals in the laboratory, the teachers in the university or some research institutes can demonstrate the anatomic knowledge to the students majoring in medicine, rendering students a direct understanding of biological knowledge, which can improve the level of medical research and make great contributions to the medical science. Without experiments on living animals, genetic technology would not have developed so quickly. Actually, most scientists attribute their success and breakthroughs to experiments on animals.
Finally, Some animals can provide human beings with essential organs for transplantation. Genetic technology will change the genes of some animals. In the near future, organs of animals will take the place of artificial organs like heart pumps, prolonging patients life.
However, research on living animals faces a moral problem because animals are also living which possess equal rights as human beings, according to many. On a second thought, it is worthwhile for the purpose to accelerate the development of science and the progress of human civilisation.
