It is no doubt true that a large quantity of different experiments and observations are being done on animals so as to design new medications. Some people argue that these experiments are not morally, whereas others state that this approach is essential for humans better life. While I tend towards the viewpoint that it is wrong to cause pain on any alive creature, I would have to support the idea that these measures should be done by scientists for preventing disease in human beings.
On the one hand, mankind have had to perform a reach variety of medical tests on animals. Firstly, this is only way to keep and enhance the rate of health in communities, because our health condition is almost relied on new medications that are made by scientists. Secondly, health providers should persuade governments that a medication is safe for human populations, hence they have to observe new medications effects on other creatures. Taking COVID-19 as an example, scientists had to examine new vaccines on animals, so as to prevent more decease in mankind societies ,subsequently if they did not sacrifice some animals in laboratory, a disaster could happen in humans societies.
On the other hand, it would be wrong to exert pain on animals. They are a alive creatures and feel pain as well as humans. According to a study, which was carried out by a group of American researchers, emerged that animals pain mechanisms are similar to humans. Furthermore, the rights for living is not exclusively for human in other words all creatures should live naturally.
In conclusion, it could be stated that various experiments on animals are morally wrong, but scientists do not have an alternative way to keep humans healthy.
