For a long time scientists have been carrying out experiments on animals for different reasons. Some experiments can be useful for people's health. But there is an opinion that it is wrong to exploit animals in this way. However, there are both good and bad points in this stage.
Undoubtedly, we have to admit there are many benefits for people, which we have not got without scientists' experiments. At first, cloning animals gives us exciting possibilities.
Secondly, scientists develop drugs to cure different diseases. There are no animal alternatives to test new medicines on. The only reliable method is to experiment on humans, but this is even more inadmissible than to use animals. Thirdly, experiments on animals help us to understand how humans and animals function.
However, many people object to such use of animals. Of course there are shortcomings in using animals in different experiments. For example, many cosmetics companies perform experiments on our small brothers for cosmetics tests. We should avoid it, as such experiments are unnecessary for people. There is point of view that it is morally unacceptable to experiment on animals, especially for those who believe that animals should be accorded the same rights as humans.
In conclusion I would like to say we cannot avoid from experiments on animals as they have proved to be a big benefit for the mankind. But we must to behave kindly and with respect to animals, with the minimum violence and cruelty.
