    Medical testing on animals is a debatable issue in the entire world and most people discuss about. This complex issue has created a common controversy between people long time ago and it is still exist until this moment. Of course there are people who completely disagree with animal testing, because they think that there is no benefit from these tests at all.  Also they allege that it is only looting of animal's life, in other words, animals will extinct soon if medical research continue. On the other hand, there are many people who agree and encourage testing on animals. They believe that this is an efficient way to discover new medicines that decrease the number of being sick and also to improve the health researches. In addition to that, they believe that animals have the same body as humans which will help scientists to study diseases. Using animals as models can help researches in learning new procedures and avoid future mistakes. According to Is Animal Testing Necessary article," Without the ability to use animals in their research, scientists' efforts would be massively hampered in the fundamental research."(2011). So, animals medical testing must be continued no matter what happens. Science researches will expand by using animals and that is why animals medical testing must continue.

      People who disagree with medical testing on animals allege that there are a lot of disadvantages from it on our lives. For instance, it is going to cost a lot of money to do medical researches on animals and it will affect the economy. A writer from neavs organization said, that there were 2.9 million mice in a research center that has been sold by 98.7 million dollars to another research center. Furthermore, ". . . for testing a chemical to determine if it is carcinogenic is the rodent bioassay, which takes up to five years from planning to evaluation and review, at a cost of up to more than $4 million per substance." 

Another reason why they want to discontinue animal's medical test, is because of their emotions. In other words, they think about the pain and how animals suffer instead of thinking about the benefits that could help people who are suffering from many illnesses. They also think that when scientists use animals in medical testing, animals will start to disappear and extinct. However, the thing that opponents do not know about, is that scientists make animal experiments to generate more and more of their kinds to prevent the extinction from happening. Besides, there are couple of advantages that people who argue against animals testing do not know about. First, using animals help scientists to find new medicines that cure many different illnesses. Second using testing animals as models help researchers to study new diseases. 

The first advantage of testing on animals, is finding new medicines that can cure many diseases around the world. Animal's body have the same complexity as human's body which help scientist finding cures for illnesses. A YouTube video have presented some researchers, and one of them has said that those living creatures are used in researches because they have the appropriate structure (Thompson). For instance, cancer treatment has developed from animals testing in the last 40 years, and the survival people from cancer have increased (Scott). Another example, it has helped researchers how to create body internal parts such as hearts, kidneys and many others. Animal's examination have made our treatments improve and help many people in getting better. So,  people who disagree with medical research on animals must know that we would not be able to find treatments for diseases if we did not do animals testing.  Furthermore, a lot of humans will die because they will not be able to get a better treatment. Isn't that a looting for human's life too? Also, if we did not do it, scientist might use humans in their tests and that could cause decreasing in population around the world. According to Rebecca Robinson who is a part of three different organization, Commissioner's Fellowship Program, Center for Devices and Radiological Health, Center for Biologics Evaluation and Research, researching on animals is a very important way important because the products of regenerative medicines need to be tested on animals before using it on humans. Based on a YouTube video that include several researchesr,it is impossible to know whether the new product is safe or works unless it went through some tests and these tests should be done first on animals(Steward,2015). Animals researching is considered as an efficient method to see the side effects of medicines(Knight and Breheny). So, what can we infer from these evidence is that medical testing on animals has helped us with finding new cures that vanished many kind of diseases in this world.   

The second advantage, is helping researchers to study illnesses that exist in every human body. The genes in human's body are similar to the ones in animal's body and that can help scientists in studying and discovering new diseases. Also, humans and animals are sharing the same diseases such as diabetes, cancer, hemophilia and so many other illnesses. Bullock, Ross, Lyeth, Bruce, and Muizelaar, believe that animal's experiments have given the chance in treating human brain injury traumatic disease before it spread and they already found new methods to beat it (1999). When scientists do these kind of examination, they will protect people and other animals from getting sick and that is because researchers will have already studied the disease before it spreads out. Animal testing have helped in curing some of the animal's diseases such as canine parvovirus, distemper, and feline leukemia virus (How Do Animals Benefit from Animal Research). Scientists will also expand their knowledge about diseases and advise people on how to protect themselves from these dangerous illnesses. Some of the opponents said that why researchers do not use computers? Well, scientist can do that but there will not be any benefit from it because animals are the only creatures that share the same genes with us. Studying animals as models for human illnesses has led to many discoveries such as new technologies, new treatments methods that will help people in the future. Moreover, it will make veterinarians help animals to recover and also to protect them from the same illnesses that infect most people. 

Finally, animals researching can help scientists in learning new procedures that can help humans. According to Rachel Hajar, in the past there was an Arab physician called Ibn Zuhr, and he used animals as models and learned new surgical procedures that can be done on humans. Using animals will improve new techniques that save people's lives and will help scientists in avoiding future mistakes.     

   

In summary, medical animals testing has a big part in the development of health researches. These tests have helped scientists from around the world to evolve medicines and find new methods of treatment to cure sick people. Moreover, animals model have helped researchers to study diseases and give them a picture about how to protect people from these new illnesses. Furthermore, using animals as models will help in learning new techniques that will save humans. An American medical progress website said, "animal research plays a crucial role in scientists' understanding of diseases and in the development of effective medical treatments."(Animals Research). So, when scientists do these tests, they do it for helping us, they do not do it for having fun. To the People who are against animal's examination must know that most of these developments in the health researchers are because of animals testing not from something else. They have to think in a rational way not in an emotional way because when they think emotionally, they will not see the benefits. In other words, they do not think with their brains, they think with their hearts. But, no matter what opponent's people say, the people who agree insist that medical researches on animals must be continued so that the developments in the health path keep going.
