Expressing an opinion-1

Many people insist that it's necessary to use animals in laboratory experiments, but I disagree with it for the following reasons. First of all, we can’t deprive the animals of their lives. These animals have the rights to live as humans do, and nobody can take others lives to do some cruel medical experiments. Besides, animals are different from humans in many ways. Therefore, we can’t make sure if these experiments would have the same effects on humans.  Furthermore, immoral scientists would do some experiments which can be avoided on animals. Thousands of animals die of these dispensable experiments every year. In light of all the points mentioned, it is obvious that laboratory experiments in which animals are used should not be carried out.
