Scientific associations reveal many treatments against human protection, results from studies with animals. The developed drugs are tested on animals before they are put on the market and used by everyone. The examination is usually tested on animals after undergoing various tests. While many would find this ethically inappropriate, testing chemicals directly on humans would provoke much more backlash. For this reason, newly produced drugs are always tested on experimental animals before being put on the market. For these processes, the business distributes the animals closest to the human by metabolic or using them. However, these rules have certain rules. The rules to be followed when working with experimental animals and what to do are explained in international regulations and guidelines for the use of experimental animals. So basically scientist test the products on animals to find out if the product is safe or not, they do some tests on animals but it cause a great harm and it hurts or even kills the animals. That’s why I think it is such a bad thing to torture and use the chemical materials on animals. There are a lot of ways to check if the materials are safe but people do not use it because it costs more. I think people shouldn’t use those brands which hurts the animals.
