Some people believe that using animals to test the safety of human medicines is cruel and unwarranted, whereas others feel it is a medical necessity. Discuss both views and state your own opinion.

Nowadays, medicine plays an important role in people's lives to prevent diseases. Creating a drug requires a process of research and safety testing, including testing on animals. Many people consider it cruel and unwarranted to use animals for drug research while others see it as necessary. In my opinion, testing on animals is pretty quite cruel, but it is an important stages for medicine research. The use of animals in drug testing is cruel because newly created drugs are often based on diseases that can be toxic and harmful to animal health or even death. Not only that, the animals kept in the laboratory are also treated badly, causing them not only physical pain but also mental pain. In addition, animal testing often does not give completely accurate results, so human testing is still required before release, so animal testing is not really necessary. Although many people think that testing drugs on animals is unjustified, in fact, this is very necessary. Since drug testing on animals can be carried out on large numbers, it is possible to quickly find methods for diseases. Testing on animals first will limit the harmful effects that can affect humans. In addition, the animals that are often used as research subjects are small animals with fast reproduction rates, so they will not greatly affect the ecosystem. In conclusion, the use of animals for drug testing is inevitable, but this research needs to be tightly controlled to protect the animals.
