" The reliance on results from animal testing for serious diseases such as Diabetes and Cancer is not only a waste of time, money, and resources, but is also extremely dangerous and inaccurate as well. This is because it is virtually impossible to produce an exact replica of any human disease in an animal. Instead, it must be re-created, thus altering its original, natural data, even if it is only by a marginal degree. Also, researchers freely acknowledge that many experiments conducted on animals contribute nothing to the well being of humans. A perfect example of this is a lung experiment that was done on foxhounds at the University of Texas Southwestern Medical Center in Dallas. After having sixty-eight percent of their lungs removed, the dogs had masks placed over their faces and were forced to run on treadmills. To accommodate the masks, scientists ground down the dogs" canine teeth. When the experiment was completed the dogs were terminated and their lungs were examined. When asked about this experiment, R. Hamlin, D.V.M. said, "The only conclusion I can reach is that tremendous pain and suffering are being inflicted upon helpless dogs under the guise of research, and the results being attained are admittedly of no benefits to mankind." Over time some of our greatest minds have spoken out against animal abuse. Ancient Greek philosopher, Pythagoras, said, "As long as man continues to be the ruthless destroyer of beings, he will never know health or peace. For as long as men massacre animals, they will kill each other." Centuries later, Charles Mayo, founder of the highly regarded Mayo Clinic said, "I abhor vivisection. I know of no achievement through vivisection, no scientific discovery, that could not have been obtained without such barbarism and cruelty. The whole thing is evil." .
Two of the most infamous testing methods used on animals - the Draize test and the LD-50 test - prove that Charles Mayo was indeed correct.
