Some people think that the use of animal for experimentation is cruel. Other think it is good for the development of science. Discuss the two sides and give your opinion.
Animal testing in some medical tests is debatable for some reasons. This public debate arouses people's interest to come up with their idea that experimentation on animals is unethical because humans have no moral right to do experiment on faunas. However, critics claim that animal testing is necessary to advance medical and scientific knowledge in some important medical discoveries. Therefore, I strongly believe that both arguments have different perspectives in terms of animal testing.
With regard to the experiment of animals, people believe that it is understandable to use animal in important scientific research as scientists need experimentation to test a new drug in order to cope the rare disease. Take scientists in America as an example, they have to find out a drug to cure a danger disease, Ebola in 2015, which kills many people in the South Africa. In this study, scientists use mice to advance the medical research and analyse the product before the drug is taken by the sufferers. As a result, animal testing helps in medical tests on a new medicine in order to combat the bacterial infection of Ebola disease.
On the other hand, others argue that animal testing should be banned for moral reasons. Firstly, experiment on animals is unethical because animals have a same right as humans, and the live of animals should be respected. Regardless of this reason, the use of animal for experimentation cannot be justified by suffering caused as there are some alternative ways that can be used to invent a new drug in medical discoveries. Finally, humans have no right to use animals in some experiments because the more the scientists use animals on medical research, the more the animals lead to extinction.
In the light of the aforementioned facts, I personally believe that the reason of animal testing cannot be accepted because scientist enable to take other means of experiment with using plants which have the similar substances like animals. While using animals as object of experimentation is cruel, in the some crucial medical tests animals are allowed so as to prevent the widespread of danger disease using a new drug. Where possible, animal testing should be restricted with the strict policy which controls the experimentation.
Therefore, I strongly believe that both arguments have different perspectives in terms of animal testing.
You don't really give your opinion, right from the beginning. I think you should have the last sentence of your introduction as a clear, concise opinion, on one side or the other. If you can't decide one way or the other, I think you should not just mention diversity, as that's weak. You should end your intro by saying, there are meritorious points on both sides of the argument.
Regardless of this reason, the use of animal for experimentation cannot be justified by suffering caused as there are some alternative ways that can be used to invent a new drug in medical discoveries.
[/CORRECTED: Regardless, the use of animals for experiments cannot be justified. The suffering it causes can be alleviated by using alternative ways. font]
[/Your sentence is way too long, and the ideas need to be clarified and condense for better readability. I broke the sentence into two shorter ones, and added word choices, which serve to simplify the read.
I think you should say, in your intro that you find either choice too black and white, and that a solution can only be reached by compromise. It seems you find it acceptable to use animals to solve major scale epidemics, but think philosophically that plants might make just as good a contribution, with equally good results. I think that's an interesting point, not many people know about.
In general, you writing is strong, and clear in presenting both sides. Your grammar and punctuation need some attention, in the ways, I mentioned; but in the end you need to make your own opinion a little clearer, right from the beginning.
