关于动物做实验癌症的研究英语作文
Perhaps no subject in the moral community is as controversial as animal testing. Animals, many people believe, merit more humane treatment. When animal-bad experiments have long been the centre of criticism, I am of the opinion that such experiments are esntial to both the well-being of human beings and that of animals.
There is little doubt, first of all, that most of the animal-bad experiments are conducted for the development of technology and to date, there is little chance of finding satisfying substitutions for animals, Animals are ud mainly becau they bear a clo remblance to humans, either in behaviour or in cell structure. They respond to external disturbances (such as electrical shock) nearly in the same manner as humans do. There is much evidence that most of what people know about themlves, including pain, stress, reproduction and nutrition, is bad on findings of animal-bad experiments. Animal testing proves one of the main approaches to predict the risk when drugs or other products are ud on humans.
Another fact to support animal-bad experiment is that animals are not the equivalent of humans, and can be ud as resources for human purpos. Animals have no capacity to recognize the rights of other species. Nor will they take in consideration the interests of other species. It is possibly one of the main reasons why animals feed on each other. Humans, by comparison, u animal experimentations not only for their own interests but also for the interests of animals. For example, some medical discoveries can be ud by veterinary surgeons to give medical care and treatment to sick animals.
Despite the justifications given for viviction, rearchers have the obligation to reduce animal testing and animal suffering. There is a growing recognition that animal tests are mostly done for commercial purpos and most of them are avoidable. For instance, the cosmetic industry has been exploiting animal experimentation simply for diversifying products and maximizing profits. The fewer cosmetic products people u, the fewer animals they have to slaughter. When scientists are empowered to carry out cruel experiments like viviction, such powers should not be abud.
To summarize, one can subscribe to the notion that animals can be taken as resources intended for the benefit of humans, although meanwhile it is certain that suffering should be controlled to the minimum during experimentation.
