Some people claim that it is acceptable to use animals in medical research for the benefit of human beings, while others argue that it is wrong. Discuss both views and give your opinion. Animals, from the fruit fly to the mouse, are widely used in scientific research. They are crucial for allowing scientists to learn more about human biology and health, and for developing new medicines. While many people believe that animals should be used in medical researches, some others are strongly against this, reasoning that it is a clear violation of animal rights. Those who are not in favor of undertaking so-called medical testing on animals claim that such tests are inhumane and unethical. They opine that we are not allowed to sentence confine innocent creatures who can feel pain and pleasure in laboratory cages poisoning, shocking, burning and kill them atrociously. In addition to cruelty of such tests on animals many reports are indicating that a large portion of medicines tested on animals did not have the same effect on humans. In view of this, more humane alternative technics such as sophisticated computer modeling, cell culturing and using volunteers is proposed. However, proponents of animal testing argue that not only is are limited tests under specific condition necessary to develop medical science, but it is also mandatory to pave the way for further advancement in the boundaries of other sciences such as space explorations and psychology. Admittedly, a shorter life span of animals than of that of humans is another green light for scientists to conduct their research on animals. Advocatesd, however, claim that alternative solutions are still limited, and they cannot rely on new methods to do necessary tests. I personally, opine that although scientific research on animals can be done in a cruelly inhumane way it was necessary during old ages. I do not see any reasonable ground torturing defenseless animals for industrial purposes. That humans at this day and age is are slaughtering animals for financial benefits is an undeniable fact. While I do agree with limited tests on animals under certain humane regulations, I am strongly against animal testing freely without specific rules.
