Many factors influenced whether a species live or not. One of the most important is due to natural while the other is to human. Insofar as education level enhancing and learning "nature selection", it make many person take it for granted that the influence of nature is greater than of human. However, further reflection shows that human action plays a more and more significant role.

First of all, no one can blind to the fact that nature as well as the adaptability of each species are the decisive factors. In nature realm, with the science and technology developing, more and more people realize that one living thing whether can be live depend on the gene inside in one's body, even though people protected them by a set of process they can rather survive for a longer time than forever, for they are eliminated by the nature fundamentally. What is more the most celebrate theory is "nature selection", proposed by Darwin who is the famous biologist, from which we can realize that if a species could not adapt to the alternation of nature ones will be excluded such as dinosaur, sanyechong and so forth. Briefly speaking, protecting species which is excluded by nature is unwise and waste.

Then, there had to be another cause why I agree that there is no justification to make extraordinary efforts to save endangered species, and these was, we cannot distinguish being exclusive species from plenty of endangered ones. Moreover, it is too difficult for human to take action to save all the endangered species according to the resource and component human being posses. With the development of economical, people around the world become richer, but we cannot deny the fact that there are numbers person still suffered starve and illness, a plenty of children  is out of school, particularly in Africa and Asia the situation is worse. Would people plunge extraordinary resource to save one or two species instead of refugee? In short, there are many restriction confirm people plunge extraordinary resource to endangered species.

Understanding that some species is inadaptable to nature as well as the resource that people could unitize is limited are the primary step to obtain advancement in the struggle effort to survive species, on no account should not we conclude plunge efforts to save endangered species. In the first place this situation is attributing to human in a large degree, for people deforest and exploit materiel crazily without thinking about the animals live in the forest and live on the forest. Furthermore, after crazily exploit resource they pull out waste gas to the air which is harmful to every species include ourselves; pull out waste water to the sea which the fish live in, through which enhances the speed of die out of species. Another factor is that people kill animals at will. One of survey reported that the number of whale is decreasing rapidly because of person capturing only for blutter which is maybe helpful to healthy, the survey also provide a set of static that one plant vanish per minute, while one animal should die out every day, over 30 species die out in the next step for they relative to them, this speed is higher than nature. Thereby, we must take best of ourselves to save species not only for the culpicity but also can vivid our globe.

In conclusion, the role of nature is decisive; yethuman may also take their own responsibility, furthermore, people play a more and more important role in both endangered species and survive them, besides the dual position will assist people to make great effort to protection species.
