With the spread of diseases that are still considered to be a nightmare not to people but also to biochemists, long-term experiments play the paramount role in the development of cure methods. A coterie of the masses believe using living creatures like animals as laboratory's testing objects will bring potentials to save human lives; however, those who disagree think that doing such a thing is nothing but wasting time and investment. From my perspective, I acquiesce in that having fauna tested using chemicals and biological substances will benefit the future ability to survive of humankind.
