1.Some people think animal experimentation should be stopped because it is cruel.Others think it is neceary for the development of science.Discu both view and give your own opinion.范文 一

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 neceitates 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 outer-space 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 neceary.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.相关话题解决

1.个人不能对环境保护做不了什么，同意不同意

2.给出解决办法 2.动物保护(动物实验)

1.共同生活在一个地球上，应该保护动物，maltreatment to animals is barbaric and uncivilized practice.但是说动物濒临灭绝是exaggerated，禁止动物实验更是irrational

2.Select the superior and eliminate the inferior, the survival of the fittest 是一个natural rule can not be violated，有些specifies缺乏生存技能，就应该被淘汰，如果人们的过渡干预反而会造成坏的作用对ecological system.当然，如果是因为人类破坏了其habitat而导致的endanger,另当别论。

3.动物实验是indispensable for medical research, all of which 是为人类造福，没有人不希望在全球范围内消灭AIDS，而这一切需要大量的生物实验来完成。而且目前还没有有效的alternative methods,计算机还不足以仿真整个生物实验，或许以后有替代方法了，就可以取消动物实验。目前能做的只能是减小痛苦，relieve pain.4.有人说吃动物的肉很残忍，让大家都做vegetarian, 在我看来很可笑，动物有生命，植物就没有生命了？这么说人类就该饿死starve to death。因此，只要不是虐待动物，将他们作为食物和衣服 is not blameworthy.5.因此我不赞成…
