题目:ISSUE121 - "At various times in the geological past, many species have become extinct as a result of natural, rather than human, processes. Thus, there is nojustification for society to make extraordinary efforts, especially at a greatcost in money and jobs, to save endangered species."
What are the limitations of our duty to save the endangered species from extinction?This question raises a variety of issues about morality and economic. The issue that there is no justification for society to make extraordinary efforts,especially at a great cost in money and jobs, to save endanger species calls for a balance in which there are both caring about the animals and leaving them along.
First of all, protecting the animals from becoming distinct because of the natural selection is useless,which is just a result of the nature law. All of us do not have the ability to change it. For example, the number of pandas in the world is limited at present. As we all know, these result from the change of the environment. The pandas in the wild can hardly adapt to the environment and live normally. The change of the environment makes the pandas not adapting to it, and the fact that they are becomingdistinct is beyond our ability to control.
Althoughwe should not care about some of the endangered animals, there is need toprotect the animals becoming endangered as a result of our activities. Most ofsuch cases we can do effective job to save them. There were many special treesalong the sea in the east of Chinain twenty years ago. However, now the trees are still being destroying, may bein the near future, without enough effective work, the trees would probablybecome endangered. If the government and the local residents pay attention tothis problem, the result could be better.
Infact we should make our effort to save the endangered animals in spite ofwhether it is the result of natural selection or human activity. Any of theanimals are the treasure of our human beings, such as the pandas, koala bears,and so on. Some of the deceases can be cured easily using the drugs made fromthe endanger animals.
Insummary, the issue of whether we should protect the animals is a complexproblem. So we should protect them on condition that spending on it with propertime and energy.
Argument 37
The conclusion of the argument is that theso-called Palea baskets were not unique to Palea. To support the conclusion,the arguer points out that the Woven baskets characterized by a particulardistinctive pattern first discovered in Palea have also been found in Lithos,and that the geological conditions and the fact that the Paleans did not have boats make it impossible and unnecessary for them to cross the river, and they have no communications. A careful examination of the argument can see how groundless it is.
First of all, the argument is based on assumptions that the people in the two cities exist during the same period of history and the geological conditions have not changed in the history, which there are noevidence to support and may be just the imaginations of the archaeologists. It is greatly possible that the river did not exist when the two city are already there. And the people can get to the other city easily without any specific efforts. So it is needed to collect more information about the two cities and the geological conditions to make the argument more persuasive.
On the condition that they are during the same period and the geological conditions remain the same in history, the arguer can not demonstrate that the people in both places have no ability to cross the river. It is possible the people in Lithos have boats or that both of them have something else that can help them cross the river and bring the baskets to the other side of the river. Without ruling out these and other possibillities, the arguer can not confidently draw the conclusion.
The fact that the forests in Palea is full of nuts, berries, and small game the arguer provides is insufficient to draw the conclusion that they do not have never crossed the river. Firstly, the arguer provides no reason to support that the forests are so wonderful. What’s more, accidences can happen now and then, we can not say that the people really did not cross justbecause they have no need to do it. Maybe some unexpected things such as a disaster of water, or disease drived the people to move to other place. Therefore, the conclusion is not well warranted.
In conclusion, the argument is not persuasive as it stands.To make it more convincing the arguer needs to provides the information including the geological conditions and the tools of the people use during their time.What’s more, I think more direct reasons are needed. |
