Second, Non-human animals are imperfect for the human body. Animal testing is not just dangerous to the animals tested on, but to humans as well. Creatures used in experimentation are deprived of everything that would seem natural to them. They are confined to empty cages for hours at a time and caused social isolation, and psychological trauma. Animal testing may not be as accurate as it appears when it comes to the health of people. Pat Thomas said that “many of the drugs approved through animal experimentation have proven dangerous to humans. In order to make experimentation more accurate, scientists should rely on human cells and carefully conducted clinical trials with humans.” Animal experimentation does not work. Unfortunately, scientists have relied on these tests, and as a result, many of the drugs approved through animal experimentation have proven dangerous to humans. In order to make experimentation more accurate, scientists should rely on human cells and carefully conducted clinical trials with humans. According to the Food and Drug Administration (FDA), 1.5 million Americans were hospitalized in a single year due to pharmaceutical drugs given to cure them. 30 percent of those hospitalized suffered further harm from the therapy they were prescribed. The Great Medical Fraud prominent researcher Hans Ruesch adds that approximately 15,000 new drugs are marketed every year, while some 12,000 are withdrawn. The reason that animal testing is causing so much harm to humans may be because of the unreliable results animal testing produces. It is true that animal systems differ from human systems. There are enough similarities to apply information from animals to humans. Animal experimentation cannot predict many of the dangerous side effects caused by new products.
