The history of earth has witnessed numerous remarkable epidemics, which were the reason for millions of human deaths. These tragedies did not distinguish between an animal and a human, even children suffered from them. One example of these epidemics was the Black Death, which had killed approximately seventy-five million people in 1350. Until now, neither human beings nor other creatures have a guarantee against the re-emergence of these epidemics, or against the spread of a new one. For this reason, we should secure some precautions to ensure the well-being of our species and the permanence of all living beings on Earth. Hence, the importance of animal experimentations arises. Since 1906, the rate of using animals has increased by 38%. In

Many people have died in the past because of taking unsafe drugs, which were not tested for their safety and usefulness for humans. However, indicating the therapeutic dose is important to assure that its degree of toxicity is low enough, and it will not cause the organism death. For example, a widely used drug, called aminophylline, which is used to treat bronchial asthma can disturb the heart rhythm because the difference between the therapeutic dose of this drug and the toxic dose is narrow, thereby damaging the organism instead of curing him. For these reasons, animal testing is essential to conserve human lives by assuring the drug’s utility and indicating its appropriate therapeutic doses. Moreover, some medications may have a fatal side effect on people, especially on pregnant women. Thus, demonstrating these effects is critical to prevent tragedies. The thalidomide tragedy is obvious evidence that illustrates the importance of identifying the side effects of a drug before introducing it. In 1957, a drug called thalidomide entered the markets as a treatment for vomiting in pregnant women. This drug has affected infants’ development and caused their birth either with shortened limbs or without limbs completely. This tragedy was a tough lesson that drugs companies had to learn. Therefore, before getting another painful experience like the thalidomide tragedy, testing the drug safety on animals is a necessary procedure that proceeds making the decision of launching this
