Therefore, animals should not be used in research or to test the safety of products. First, animals' rights are violated when they are used in research. Animals are subjected to tests that are often painful or cause permanent damage or death, and they are never given the option of not participating in the experiment.
that's true, because if we used them for research there's a possibility that the animals we're using is not possible to become extinct, and also they have families, like humans, us.
