One more argument that proponents for animal testing have is that since scientists use the “three R’s” method, it prevents animals from being abused. Proponents claim that scientists all over the world are taught this method. One of the goals is to reduce the amount of animals used in experiments. Scientists do this by “improving experimental techniques, improving techniques of data analysis and share information with other researchers” (“Experimenting on Animals”). Another goal is to refine the experiment to lower the suffering animals have to endure. Scientists achieve this by improving living conditions and medical care and using less harmful techniques. Lastly, scientists strive to replace animal experiments with alternative methods when possible by using cell cultures, computer models and the various other alternative methods. 54% of animal tests in the US did not involve any distressful situations according to USDA ("Animal Welfare Act") and proponents claim that this fact proves that scientists really do use the “three R’s” method.
