Scientist use living animals to carry their research. Some people think it is
interesting, while other people think it is cruel. What do you think?
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 favor of carrying out
experiments on animals.
Firstly, scientists can do initial experiments on animals to test the effect of
new medicine. Scientists have founded so many milestones on the way to
medical development. But they can not find effective treatment to some
diseases like cancer and HIV, 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 to these diseases, making great breakthroughs in the field of
medicine.
Secondly, by using living animals in the laboratory, lecturers in universities
or in some research institutes can demonstrate the anatomic knowledge to
the students who are 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 could 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’ lives.
However, researches on living animals face a moral problem because
animals are also creatures in the nature which possess equal rights as human
beings. On second thoughts, it is worthwhile for the purpose to accelerate
the development of science and the progress of human civilization.
