Animal Testing: The Positive Effects Of Animal Experiment

For hundreds of years, human beings insist on finding means to create possibility for progresses in the scientific and medical field. In order to meet the expectation of people to develop skills for the bright future in researches, teaching, testing, safety evaluation and achievement evaluation in the field of life science, human beings start to use animals for experiments. Even though some people argue that sacrificing the innocent animals for experiments is merciless, animal experiments for human use should be kept based on the positive effects of animal experiments, which include the indispensible achievements in medical science, the advantage of animals’ simple body structures and the enacted laws to protect experimental animals.

To begin

As we all know, the structure of human body is extremely complicated with eight systems and thirty-six essential organs. Hence, human have difficulty applying their research results on human body even with accurate computer simulation. “It is possible to do basic tests on cell lines but this does not replicate the complex interconnected processes of a live body and can never predict potential side effects on different organs within the body”(Anderson). In addition, animals, especially mammals, share a common ancestry with human being in fact, thus their organs, nervous system and other constructional details work similarly as human body does. “The DNA of mice is 98% similar to that of humans. Chimpanzee DNA is 99% similar” (Anderson). As a consequence, animals with simpler internal body structure can be the more suitable choice to complete medical

Human beings have no right to violate experimental animals’ life since life is equal in our moral values. Nevertheless, their argument fails to recognize that human beings have already set laws to regulate treatments to animals. The limited laws are able to assure that experimental animals are treated rationally so that animals can avoid from being maltreated in labs. Take the 3R Principle as an example, the validation and implementation of the principle can safeguard experimental animals’ health. In the principle, 3R represents “reduction”, “replacement” and “refinement” respectively. First, institutions should reduce the number of experimental animals as many as they can. Second, researchers must use insensible materials instead of living animals when it is possible. Third, researchers need to be kind to animals not only by improving their living environments but also by ensuring particular care to keep them from pain and panic. In this way, laws are able to assist in protecting animals and promoting the reasonable animal
