Other think it is good for the development of science. Discuss the two sides and give your opinion.
We often say that animals are our best friends. However, in real life, we human beings are often very selfish. Sometimes, we often betray this friendship by torturing and even sacrificing the lives of our “friends” for certain selfish reasons. Vivisection, or animal testing, is one of the selfish behaviors that we frequently show.
First of all, I’d like to say that animals have feelings, thoughts and dignity like men. Both scientific researches and life experience have long proved these to us. A knife cut on any part of our body would incur sharp pain. Facing death that is imposed on us, we would be terrified out of our wits. Being humiliated for no justified reason, we would think of death. When have we ever realized that animals have the same feeling as they are treated the same way?
Some people may say, without vivisection, there would not have had so many scientific discoveries. Yes, it sounds all reasonable. Yes, many a scientific finding was achieved by animal experimentation. But, who dare say that without vivisection, the world would stop moving forward? I’m afraid no one dares say this, for human society will always keep moving forward and many scientific findings are simply a matter of time.
Admittedly, not all animal experimentations are cruel. Some simple and pain-free experiments can benefit both mankind and other animals. For instance, some efforts which aim at increasing the group number of some endangered species can provide opportunities for them to thrive again on the earth so that they can share with mankind this beautiful world. Such kind of experiments should be encouraged.
We can not change the past. We only have the present and the future. What is gone is gone, including those animals that had suffered great pains and even sacrificed their precious lives for the scientific and technological progress of mankind. However, we should bear in mind that while we are thinking about our own benefits, we should also have other animals in mind.
