The word "conservation" has a thrifty (节俭) meaning.To conserve is to save and protect, to leave what we ourselves enjoy in such good condition so that others may also share the enjoyment.Our forefathers had no idea that human population would increase faster than the supplies of raw materials; most of them, even until very recently, had this foolish idea that the treasures were "limitless" and "inexhaustible". Most of the citizens or earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.
Fifty years ago nature study was not part of the school work; scientific forestry (林地) was a new idea: timber (木材) was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied longterm climatic cycles in relation to proper land use; even the word "conservation" had nothing of the meaning that it has for us today.
For the sake of ourselves and those who will come after us, we must now set about repairing the mistakes of our forefathers.Conservation should, therefore, be made a part of everyone's daily life.To know about the water table (地下水位) in the ground is just as important to us as a knowledge of the basic mathematic formulas.We need to know why all watersheds need the protection of plant life and why the running current of streams and river must be made to yield their full benefit to the soil before they finally escape to the sea.We need to be taught the duty of planting trees as well as of cutting themWe need to know the importance of big, mature trees, because iving_space_for_most _of_man's_fellow _creatures _on_this _planet _is_figured_not_only_in_square_measure_of_surface_ but_also_in_cubic_volume_above_the_earth.In brief, it should be our goal to restore as much of the original beauty of nature as we can.

健康环保类文章阅读技巧：
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考，理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文，从结构上看大致可分为三个部分：
第一部分一般是文章的首段，主要用来提出文章的主题，即文章想要阐述、说明的主要内容；
第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；
第三部分是结尾段，对文章的主题进行归纳总结。这类文章多用一般现在时，而且一般多使用客观性词语表述。有时为了强调客观性，也常使用被动语态。
从近几年的考试题来看，科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节，很多同学对此类文章感到费解。但一般的科普类文章都是就事论事，需要逻辑推理和想象的时候较少，因此此类阅读题也没有同学们想象中的那么难，只要多加训练，就能较好地答题。
