At various times in the geological past, many species have become extinct as a result of natural, rather than human, processes. Thus, there is no justification for society to make extraordinary efforts, especially at a great cost in money and jobs, to save endangered species.
------正文------
The statement illustrates that many species have become extinct as a result of natural, rather than human, processes in the geological past, which is a piece of fact proved by modern science. As a result, it states that there is no justification for human beings to make extraordinary efforts to save endangered species, which is rather misleading than reasonable. Currently, saving endangered species is not only a sort of responsibility, but also a necessary effort to maintain survival, for human society.

First of all, though many species in the geological past have become extinct due to natural processes, in modern society, much more species have been disappearing as a result of human activities. Through land using, agricultural production, industrial processes, and other social activities, human beings have been robbing, polluting, and confusing the homeland of numerous species. According to scientific studies, thousands of species become extinct each year, and this speed is much faster than that of any other geological times. It is human beings rather than natural processes that have induced this situation, and therefore they cannot escape from their responsibility to protect endangered species.

Besides, saving endangered species is far beyond a kind of responsibility, but relates to human survival. As what has been discussed, in modern society, various species become extinct artificially rather than naturally. In other words, this process goes far away from natural evolvement. Because of the complexity of nature, the following changes are not easily predictable. The disappearance of a single species can cause unimaginable suffering to the whole ecosystem. Like a stone dropped into a lake, the influence caused by the extinction of one species will impact severely on its related species, and will then reach much more species. Though human beings are able to leave on this beautiful planet, no one knows what will happen when numerous species have been killed, when ecosystem has been destroyed, and when this planet is not beautiful any more. Thus, in order to ensure the survival of modern human beings and their future generations, endangered species must be protected.

In conclusion, in modern society, many species have been disappearing as a result of human, rather than natural, processes, which is unlike what has happened in the long geological past. Hence protecting endangered species is a responsibility which cannot be refused by human beings. Moreover, human beings have to save these species in order to maintain the natural evolvement of ecosystem, otherwise they cannot guarantee their following security.
