The author asserts that there is no need for society to cost a large amount of money and jobs to save endangered species, for the author ascribes the extinction of many species to natural processes, rather than human processes. (这样用自己的话修改背景大牛们说可以得高分哦)In my point of view, however, we human inevitably have the responsibility to make great efforts in the salvation of some endangered species, and that is necessary and beneficial for us to do so(我觉得句子太长,可改为which is...,把逗号和and去掉).
In the first place, no one can deny that human factors are the primary causes of the extinction of some species. With the rapid development of industry and technology, human beings do much harm to the survival of many species and impel the extinction of some species. Firstly, human beings often massacre or destroy a mass of some species(重复了,改为some of them), merely for the exploitation of food, material or medicine. This directly and sharply lead to the rapid decrease(in) number of the species. Secondly, human beings' over exploitation of forests and consequent spread of desert, deteriorate or destroy the habitat of many species. Last but not the least, many environmental pollution problems caused by human also do great harm to many species' living, the waste water from the factories poured into the river causes a great loss of the aquatic life; acid rain, soil erosion and global warming are also severe assaults to the circumstance for all the species. Due to the above mentioned reasons, human beings have caused a great threaten to many species' survival and they should restrict their wrong deeds to control the rapid species extinction.(这一段的结构层次非常清晰,论证语言也很有逻辑,就是first和second差点小例子,不如最后一个小论点有力)
In the second place, human beings are tightly related to all the other species, thus great species extinction also would bring serious influence even disaster to us. It is known to all that, even(every?) kind of animals or plants, including human beings, is a part of an entire food chain. Every part of the food chain is integral and indispensable, and each part is dependent on other elements in the chain. For example, if one kind of plant vanished, and there are no alternatives for the animal that depends on the plant for living, the animal may also in danger of distinction. By the same token, another animal that feed on above animal will also be in threaten.(这个可否用具体例子,不然this animal that plant 会把人搞昏的:D) The vicious circle will finally lead to the demolishment of the whole food chain, and it is inevitable for human being to be bogged down to the predicament of insufficient food and material supply.(这句话超棒) On the contrary, if there are various species, even though one kind of species disappeared, the related species that are influenced may find other alternative species to maintain their livings and the food chain continues to work healthily. Therefore, the diversity of species would contribute to keep the integrity of the whole food chain, and ensure the stability of human beings' lives.
However, it is no denying that some species' extinction are caused by natural factors, which are the incompetence of the species and the natural selection function. It is the natural principle that incompetence species will be eliminated. Thus it is meaningless for human beings to make great efforts to save(+all the) endangered species mentioned above, that is a waste of money and work(这句话太绝对了,是不是完全否认了你上述的观点?+all the是不是就好些?). Even if human beings' salvation may help them to live longer, they will inevitable to be eliminated in recent future for their connatural incompetence and inadaptability to nature.
To sum up, from what has been discussed above, we can finally draw a conclusion that human beings should realize the importance of the diversity of species, which is beneficial to the balance of the biosphere and human beings' lives. We should rectify the wrong deeds that accelerate the species distinction and put emphasis on the salvation of endangered species.
