Sustainable management is seen as a practical and economical way of protecting species fro

Sustainable management is seen as a practical and economical way of protecting species from dying out. Instead of depending on largely ineffective laws against poaching (偷猎), it gives local people a good economic reason to preserve plants and animals. In Zimbabwe, for instance, there is a sustainable management project to protect elephants. Foreign tourists pay large sums of money to kill these animals for sports. This money is then given to the inhabitants of the area where the hunting takes place. In theory, locals will be encouraged to protect elephants, instead of poaching them because of the economic benefit involved.
This sounds like a sensible strategy, but it remains to be seen whether it will work. With corruption in these developing countries, some observers are skeptical that the money will actually reach the people it is intended for. Others wonder how effective the locals will be at stopping poachers.
There are also questions about whether sustainable management is practical when it comes to protecting forests. In theory, the principle should be the same as with elephants --- allow logging companies to cut down certain number of trees, but not so many as to completely destroy the forest.
Sustainable management of forests requires controls on the number of trees which are cut down, as well as investment in replacing them. Because almost all tropical forests are located in countries which desperately need funds from logging, there are few regulations and motive to do this.
One solution might be to confirm wood comes from sustainably managed forests. In theory, consumers would buy only this wood and so force logging companies to go green or go out of business. Unfortunately, unrestricted logging is so much more profitable that wood prices from managed forests would cost up to five times more --- an increase that consumers, no matter how green, are unlikely to pay.

(答案→)C 解析：【小题1】由题干关键词sustainable management可以定位到文章第二段首句This sounds like a sensible strategy, but it remains to be seen whether it will work.和第三段首句There are also questions about whether sustainable management is practical when it comes to protecting forests.可知，这两段是在介绍可持续管理是如何进行的及可能遇到的问题。避错指导：A)文章所论述的是可持续管理用于环境保护，但没提到用于商业领域；B)第一段虽然提到反偷猎法有些低效，但并未说可持续管理比法律更有力；D)在文章并未提及。【小题2】推理判断题。由题干提示定位到第一段可知，该段第一、二句话解释了可持续管理的定义，接着就以津巴布韦为例来说明可持续管理到底是什么。因此B)符合提干要求。避错指导：A)从津巴布韦的例子可以看到可持续管理还是有效的。C)文中未提及。D)并不是举此例的目的。【小题3】语义理解题。由题干提示定位到第五段第二句In theory, consumers would buy only this wood and so force logging companies to go green or go out of business.可知，消费者将只购买采伐可持续管理森林的木材，由此迫使伐木公司只有以保护森林为前提进行采伐才可以。避错指导：A)文章未提及，也不是go green的意思。B)说的是字面意思。D)文章未提及。【小题4】主旨大意题。文章第一段首句Sustainable management is seen as a practical and economical way of protecting species from extinction.就提出话题，即可持续管理被认为是防止物种灭绝的可行而经济的方法。全文通过实例以及现有问题等进一步说明这种方法的可行性。避错指导：A)、C)文中未提及。D)所说的太宽泛，这里只论述了保护动植物的一种方法。【小题5】观点态度题。纵观全文，作者在第二至五段都在探讨应用可持续管理可能会出现的问题，所以推断，作者对可持续管理的可行性持有怀疑态度。避错指导：A)、B)和C)都不正确，虽然作者持怀疑态度，但并没有完全悲观或否定这种方法。

就是这个解释
