Some people think animal experimentation should be stopped because it is cruel Others think it is necessary for the development of science Discuss both view and give your own opinion
Animals were friend of foes of humanity at different times of the human history In modern times experiments upon animals have long been a breeding ground for spirited debate Some animal right activists argue that we should ban animal experiments altogether because putting animals through experimentation is unjustifiable on moral grounds Yet some other people contend that the advancement of science necessitates animal testing Personally I believe both their views have merit and demerit
Granted empirical evidence suggests that many animal experiments are performed callously without any attention to the discomfort or pain that laboratory mammals endure First and foremost improper confinement of test animals such as locking them up in cramped cages is inhumane It can gravely disrupt natural biological functions of the test animal Further the effects of vaccination and vivisection conducted on live mammals can be chilling They may in some case even constitute sheer torture of live animals
However from a more pragmatic perspective evidence bounds that animal subjects are still an indispensable part at this point In the first place it is manifest that drug experimentation on live mammals is far more effective than experimentation on bacteria or on other lower species in testing drug safety Drugs that have severe potential side effects on Homo sapiens must be tested by pharmaceutical companies on live mammals first to ascertain their toxicity In the second place in space research live animals are still the only practical alternative to humans in testing living creature reaction to outerspace experience on a flight not considered to be sufficiently safe for human astronauts Lastly lab research about the behavioral tendencies of chimpanzees gorillas and other members of the primate group is also necessary It produces outcomes consistently advancing anthropological and genetic studies
To conclude I concede that experiments upon animals may induce suffering to the test animals However I am convinced that there are no feasible alternatives to this methodology at the current stage of scientific development On balance I think that we should allow animals testing to be continued but at the same time we use techniques such as anesthetic to minimize the pain of the test animal
