Is there no responsibility for human society to make extraordinary efforts to save endangered animals just because many species' extinction in the past is an outcome resulted from natural processes? The speaker claims so, while in my point of view, although in some extent the extinction of certain species is an inevitable phenomenon of natural processes, we human beings, as the dominant species in the earth, have the undeniable duty to save endangered animals even at a great cost on money and jobs.
The speaker argues for his/her notion on the ground that the extinction of animals is none of our business. I concede that this argument is plausible at the first glance.As is known to all, dinosaurs, the strongest animals lived in the earth hundreds of thousands of years ago, disappeared from earth forever because of their failures to adapt to the change of weather pattern. From this scientific fact, we can say that the extinction of dinosaurs and some other commensurate animals is a direct result of their failure to " natural selection".
Nevertheless, now the condition is different. It is worthwhile for us to notice that although our earth has not experienced such dramatic weather change for a long time, the rating of extinction of species becomes much higher than before. It has been estimated that the total number of animals that has become extinct in the last ten thousand years during which human being exists far outnumbers that of the last ten billion years. The most substantial and direct factor leads to this phenomenon is human beings’ improper exploitation and serious destruction of natural environment. The following example is just cases in point. Since we regarded whales as a kind of delicious food and their skin has become popular material for fashion clothes, the number of whales has continually decreased due to our excessive preying. Although several years ago, an organization whose aim is to protect whales set up a movement to help people realize that if no concrete steps are taken, whales would disappeared from our earth in the near future and urged the government of every country to ban the preying of whales. But the result is far from satisfactory; some countries like Japan and Norway disregard this suggestion and still permit the poaching of whales. Therefore, the extinction of some species is just the consequent of the explosion of our lust. Can we still claim that we are innocent? Of course not, we must be responsible for what we have already done, and what we can do now is to try our best to save the endangered species even at a large cost.
Additionally, taking the benefit we acquire form the existence of animals and the fact that animals are our most loyal friends into account, trying our best to protect them is the best way to pay for them. We live in a biosphere where every species interplays with the other. Every species including human is like a joint of a chain of life, each other’s existence is totally depend on the existence of the other, if one joint is broken, the entire chain will be destroyed. The instance of some insect-eating animals such frog, spiders and woodpecker whose population has been reduce dramatically as a result of the use of TNT just capture the essence of what I am trying to say. These animals destroy so many insects that are the greatest enemies to human race. If not for the protection we get from those insect-eating animals, it would be impossible for us to live in the world visualizing that those insects would devour all of our crops and kill our flocks and herds. Scientists estimated that the total weight of all the pests that are destroyed by those insect-eating animals in Britain in one year would be greater than the weight of all people in the country. Consequently, protecting the animals especially some endangered animals is not only charitable action, but also a way to earn much opportunity for our own living.
In sum, although some extinction of species is a result of natural process, if all factors are contemplated including the corporeal and spiritual benefit we acquire from animals and the destruction we do to the environment and animals, the necessity of saving endangered animals has become more and more urgent. In the last analysis, the diversity of creature is the symbol of earth and whether we try to protest endangered species is just the test that imposes on human beings to test us whether we are the failure of “natural selection” or not. |
