Today a lot of companies test the safety of their products on animals. Because some people think animal experiments are morally wrong and it is cause animals to suffer, they divided into two groups. The first group thinks that experiments on animals should be banned, while another group believes that these experiments have a lot of benefits to humanity. Firstly, I guess that these experiments are morally wrong, but I disagree with the statement that they should be stopped, because if they do not test their products, they can harm someone. However, I believe that in the future, scientists will be able to improve the production technology and these immoral experiments will be stopped.
