Expressing an Opinion - 2

Do you support that researchers use animals in laboratory experiments? In my opinion, I regard it as a crult thing. First of all, it is not fair for the animals on account of they are still have their rights. Owing to the activity, there must be many protesters who are against to the behavior for the rights of the animals in the law. Moreover, the results of the animals in the experiments which are conducted by the researchers don't always correspond those are done on people. If the consequence on people doesn't meet the results done on animals, then the animals are just sacrificed. Eventually, the animals' gene is possiblely changed during the experiments. If some of the animal escape one day, then they may reproduce their generation and develope the strange gene. That will casue a big problem for other creations to be disturbed by the mutation animals. For the views above, it is very improper for the researchers to perform the experiments on animals.
