The California Biomedical Research Association states that nearly every medical breakthrough in the last 100 years has resulted directly from research using animals. Animals are extremely important to medical testing. Without animals to complete this research, people wouldn't have the vaccines and treatments for sickness and diseases. Experiments in which dogs had their pancreases removed led directly to the discovery of insulin, critical to saving the lives of diabetics. Animals testing also isn't as inhumane as it might seem. Animal medical tested has contributed to help understand a numerous amount of illnesses like breast cancer, brain injury, childhood leukemia, cystic fibrosis, and malaria. People often wonder why we use animals instead of humans to do our research. One of the reasons is because even the most powerful supercomputers are unable to accurately simulate the workings of complex organs such as the brain. Factors as well as lifespan come into play too. so researchers can study the effects of treatments or genetic manipulation over a …show more content…
Many animals can suffer from the research depending on the nature of the subject, but, the AWA (Animal Welfare Act) also requires regular inspections by veterinarians. All proposals to use animals for research must be approved by an Institutional Animal Care and Use Committee (IACUC) set up by each research facility. According to Nature Genetics "stressed or crowded animals produce unreliable research results, and many phenotypes are only accessible in contented animals in enriched environments, it is in the best interests of the researchers not to cut corners or to neglect welfare issues." Also, animals may even benefit from testing in the end. Animal testing has also been instrumental in saving endangered species from extinction, including the black-footed ferret, the California condor and the tamarins of
