Animal testing has also led to substantial medical benefits to animals. "Over 80 medicines originally developed for humans are now used to treat pets, farm animals and wildlife, including anesthetics, tranquilizers and painkillers" (Americans for Medical Progress, 2002). Treatment for parasites; prevention of heart worm; vaccines for rabies, distemper, feline leukemia, tetanus, parvo virus and infectious hepatitis; anthrax skin grafts for wounds, and surgery for traumatic injuries are just a few benefits that would not be available to animals without animal testing. It is undeniably true that a large number of medical advances could never have been made without research performed on live animals. These advances include treatments for anthrax, rabies, rickets, rheumatoid arthritis, whooping cough and leprosy; the prevention of polio, diphtheria, measles, tetanus and rubella; the discovery of insulin and Rh factor; the development of antibiotics, anticoagulants, modern anaesthesia and open heart surgery; advances in organ transplantation; and the sequencing of the human genome (Americans for Medical Progress, 2002). For instance, studies involving the use of "approximately 9,000 monkeys, 150 chimpanzees and 133 human volunteers ... were necessary to solve many problems before an oral polio-virus vaccine could become a reality", according to its developer, Dr. Sabin (cited by Americans for Medical Progress, 2002). Animal research also lays the foundation for treatment of other diseases. While it is true that HIV causes AIDS only in human beings, it is also true that "we would be in absolute, utter darkness in AIDS if we hadn't done decades of basic research into animal retroviruses" (C. Everett Koop, former U.S. Surgeon General, cited by Americans for Medical Progress, 2002). Additionally, medicines taken by AIDS patients would not have been developed without animal testing (cited by Americans for Medical Progress, 2002). Arguably, human mortality rates would be much higher if animal research had never taken place. Smallpox and other epidemics would continue to kill large numbers of people worldwide; tens of millions would die prematurely death from heart attack, stroke or kidney failure due to lack of medication to control their high blood pressure; most people with insulin-dependent diabetes would die; children with acute lymphocytic leukemia would die in the absence of chemotherapy (Americans for Medical Progress, 2002)
Animal testing is not alway about drugs there are also unnecessary animal testing when they test cosmetics on the animal. For example according to Peta there are experiment around the world where they test makeup such as mascara on bunnies, Mascara has many chemicals in it that irritates the eyes of the bunnies in the experiment causing the eye to redden and even make the bunnies completely blind. Also when it comes to drug testing 92% later fail human trials. in other words 9 out of 10 drugs do NOT pass the FDA. Furthermore animals have many differences to us for example the animals that are mostly used in experiment are rats mice birds dogs and cats. Did you know that the pill Tylenol actually can kill cats while it helps humans every day and is used daily. Many scientist say that we will go back to the "dark days" if we do not use animals. However this is not entirely true there is new technology we can use instead of animals. For example we have the technology to actually create human tissue animals don"t have to be used consistently in experiments at all but scientist don"t always seem to realize that and just continue to use animals in experiments that can be painful.
