The moral issues on animal experiments concern the need to protect human life. The gains in human’s health and well-being has out weight the cost in animal suffering. Research on animals may be deemed necessary for a variety of reasons; to develop vaccines and or cures for diseases. Animals have been studied since the ancient Greeks in the 4th and 3rd centuries BCE, with Aristotle (384–322 BCE) and Erasistratus (304–258 BCE) who are among the first to perform experiments, on living animals to advance human knowledge. Five centuries after Erisistraus used animals to study body functions .Today, animals are used in laboratory research studying cosmetics, drugs, household products and equipment. Animal experimentation and dissection also take place in schools and universities. It is a type of research that plays a key role in medicinal and biological research. It has provided us with countless medical breakthroughs and continues to provide the scientific community with medical advances, yet it is still a very controversial topic in society. Medical research involving animals has dramatically improved the health of the human race over a significant period of time. Advances in antibiotics, insulin, and other drugs have been made possible through research done on animals. In order for scientists to create new drugs, that help cure diseases, they have to be able to test them. Scientists have found that many animals have similar physical processes to humans. Observing and examining how a new drug affects an animal makes it possible to find out how new drugs might affect the human body. Animal testing saves human lives. It would be wrong to test new drugs on humans. I would not want to get into a situation where some people, like prisoners or soldiers, were forced to be part of medical experiments which has happened in the past due to a lack of volunteers "Biomedical advances depend on research with animals, and not using them would deprive humans and criminals of the benefits of research" (American Media Association74). I also wouldn’t want to put people’s lives at risk by not properly testing new drugs and cures before giving them to patients. Throughout our history and research medicine it has been proven that animal testing has helped to develop vaccines against diseases like rabies, polio, measles, mumps, rubella and TB, antibiotics, HIV drugs, insulin and cancer treatments rely on animal tests.
