Scientists should be allowed to use animals for medical research . Do you agree or disagree?

The use of animals in scientific research has long been the subject of heated debate. From my point of view, they are crucial for allowing scientists to learn more about human biology, health and for developing new medicines but animal testing is cruel and inhumane. For some following causes, we will know the reasons why scientists should not use animals in research. Firstly, no animal model is ever perfect and there are still many differences between model organisms and humans. The anatomic, metabolic, and cellular differences between animals and people make animals poor models for human beings. Secondly, drugs that pass animal tests are not necessarily safe. The National Institutes of Health (NIH) has noted that 95 percent of all drugs that are shown to be safe and effective in animal tests fail in human trials because they don't work or are dangerous. Next, animal tests may mislead researchers into ignoring potential cures and treatments. Some chemicals that are ineffective on (or harmful to) animals prove valuable when used by humans. Aspirin, for example, is dangerous for some animal species. Intravenous vitamin C has shown to be effective in treating sepsis in humans, but makes no difference to mice. Finally, it is definitely unethical. The scientists have to sentence 100 million thinking, feeling animals to life in a laboratory cage and intentionally cause them pain, loneliness, and fear. In conclusion, it should be optional to use

animals in drug testing and we have to find out alternatives solutions as soon as possible and develop them instead of researching experiments on using animals.
