There are many compelling reasons why we should continue to experiment on animals. The life of a human being is ultimately more precious than that of an animal. Without animal research, drugs as we know them today would not exist. Animal testing has allowed science to advance and find treatments for viruses, produce antibiotics for some deadly diseases, infections, and preventative means in the form of developing vaccines to cure diseases. Furthermore, the moral obligations factor requires the fact that there are excessive structures with laws in place to protect the animal from abuse and mistreatment, as all animal testing proposals must be approved by an institutional care and use committee of animals. According to ProCon animal testing, the report discusses the following aspects. Animals are appropriate test subjects due to their short lifespan which has provided scientists with significant progress in their research, and animals themselves can benefit from research that is directly associated with ethical aspects to prevent the use of human subjects . Animal experiments played a crucial part in the development of modern medical treatments. Researchers continue to rely on animal testing in response to the emergence of new diseases. (www.pro-test.org.uk) At the end of the 19th century, several deadly diseases such as smallpox, rabies, plague, cholera and typhus appeared. As a result of vaccinations developed using animal testing. Furthermore, the experiments have saved millions of people around the world (www.historyofvaccines.org). The work of Louis Pasteur and others has inspired many modern scientists to establish the causes of the virus and to develop vaccines for numerous infectious diseases. His investigation relies heavily on…half of the paper, which includes the black-footed ferret, Brazilian tamarins, and the California condor. (www.animal-testing.procon.org) In conclusion, animal experiments have proven to be an essential part of our society and have shown many changes in results regarding vaccination, antibiotics and modern drugs. These all derive from animal testing and research by professionals, following the laws and regulations put in place to ensure the safety of the welfare of the animals tested. Furthermore, in some cases animals can also benefit from these experiments since particular animal diseases have been prevented. This is directly linked to decent research experiments, as animals are adequate test subjects compared to volunteer human subjects due to the use of invasive experimental procedures that are unacceptable to impose on humans.
