Absolutely, I think it doesn’t give as accurate information on what is actually good or bad for humans as if you tested things on volunteer humans. There are plenty of sick people that would be willing to participate in research. Beyond that, science has found other ways of knowing what’s good and bad without actual testing on living things. Molecular sciences offer reverse engineering of medicinals from plants known to have beneficial effects. Since I’m not a scientist I can offer other proof only knowledge in general that there are ways of obtaining knowledge necessary without testing on live creatures. Where is our humanity?
