It’s commonly argued that animal testing has or hasn’t increased the average lifespan of humans by 23.5 years? Facts of Why animals are used in scientific research
Over 100 million animals are used every year in the United States as models in biological and medical research to study human disease, injury, development, psychology, and anatomy and physiology. Research involving animals has played a vital role in virtually every major medical advance of the last century. Even today, there is no complete alternative to biomedical research with animals. The vast majority of research animals are mice and rats bred for this purpose. Dogs, cats, and non-human primates together account for less than one-half of one percent of the total, and this number has declined for more than 25 years. Since 1979, the number of dogs and cats needed in animal research has declined by more than 50%. The number of non-human primates needed represents less than .2% (.18% in 2004) and has remained relatively constant—in the 50,000 per year range—for the past decade. History
The history behind animals being used in scientific research is that is started In Europe and in the US by the early 1900's and especially during and following World War I the benefits of animal research continued to be recognized. Following the Nuremberg Trials for atrocities by the Nazi's during World War II, society spoke loudly demanding no research on humans until animal research had made such research a reasonable risk. Today, the majority of people in our society do agree with the idea of the humane and responsible use of animals in research.
There is safeguard standards for scientific studies on animals * The USDA has set forth federal regulations governing the care and use of animals in biomedical research that are considered even more extensive than those covering human research subjects. * The Animal Welfare Act sets standards of care for research...
