Greenpeace

I am sorry that I have been unable to add for the past few months, but here I am again! I will start on a subject that I feel an interest in, and that is scientific testing. I am under the belief that if you are to develop a medicine or other product would it not be best to test it on the subjects that are the target group? I mean why test makeup on animals when they are going for humans? Or why test dog food on cats, or humans if it going for dogs?
