Should animals be used for scientific researches?

    In the past, humans used to use many animals for various activities like transportation, agriculture, security, or eating. Today, people are sharing the world with animals and they do not use animals for these activities no longer. We are using animals to feed at homes, blind people and researches. Nowadays, using animals for scientific researches subject is occupying our minds. Some people are saying that animals should be used in scientific researches for human health and other people are saying that animals should not be used for scientific researches.

     At the present time, a lot of important discoveries and inventions have discovered and invented  thanks to animals. Why should we use animals for researches? For example, serum has produced thanks to horses. Scientists are using mouses for scientist researches for human health. In this way, many people’s life was saved by animals. In Cold War, louses, dogs and monkeys were used for space researches. Thus, they have helped to humans about space obscurity. Thanks to animals, many researches have succeeded. Especially, animals used for cancer help to cancerous people. Also, technology has developed and scientist do not mistreat animals. If animals are not used for researches, should scientists use humans? Which one is better?

     On the other hand, many people are saying that animals should not be used for researches. Because they are alive. They have soul. They have a lot of rights. This situation is not correct ethically. They are not used for researches because of they do not have any will and mind. They believe that animals suffer during researches. In addition, many establishments have established for this aim and  many people are working for protecting animals. Cannot scientists use technology instead animals?

     In conclusion, although many people say that animals should not be used for researches, I believe that human life and health is more important than animals. Using animals for researching is cheaper than using human for researches. Therefore, animals can be used for the sake of human life. My advice is people should not compare animals and humans because they are different presence.
