Many people debate that all experimentation on animals is bad and should be made illegal, while others are of the opinion that crucial scientific innovations can be derived from experimenting on animals. In my opinion, it is justifiable to experiment on animals as long as it is done ethically . Clinical trials are done on animals to help produce vaccines, medications , which in turn help human well being. Furthermore, humans and animals share similar physiological similarities , which has supported the eradication of certain diseases as medications are first tried on animals before being used for human consumption. By doing this, the lives of human volunteers have been spared greatly.
