今天是4月22日，是“世界地球日”，人类历史上的第一个“地球日”，是1970年的今天由美国哈佛大学法学院的一个刚满25岁的学生——丹尼斯·海斯在校园发起和组织的，如今他被誉为地球日之父。

Today is April 22nd, is the "World Earth Day", the first "Earth Day" in the history of mankind, is today in 1970 by a USA Harvard University law school, just over 25 years old students in Campus -- Dennis Hays initiated and organized, but now he is known as the father of earth day.

也许有同学认为，关心地球环境是大人们的事，或者说这是环保部门的事，与我们无关。其实，大家都知道，我们所有的人都居住在同一个地球上，都是地球村的村民，地球环境与我们每个人的生活是息息相关的。下面我以我们生活中的必需文具──纸为例，说明节约用纸、合理用纸与保护地球环境的关系。

Maybe some students think, to care for the earth environment is the thing, or that it is a matter of environmental protection departments, has nothing to do with us. In fact, we all know, we all live in the same earth, all the villagers, the earth's environment and our lives are closely related. Below I to the necessary stationery in our lives -- as an example to illustrate the relationship between paper, save paper, paper and reasonable to protect Earth's environment.

我们每个人每天都在用纸，用各种各样的不同类型的纸。你统计过吗?你每天要用多少张纸?一星期要用多少纸?一个月乃至一年要用多少张纸?统计之后，我们会发现这一结果是非常惊人的。

Each of us every day in the paper, using a variety of different types of paper. Your statistics? You every day how much paper? How much paper for a week? A month or even a year how much paper? After the statistics, we will find that this result is astonishing.

一张纸从何而来?造纸的原材料主要是由树皮等植物的纤维“变”来的。一棵树往往需要长几年、几十年才能被人类利用。而人类有时却很无情，电锯声中，几十年长成的大树轰然倒地。那些木材，被运往造纸厂，变成了一张张纸。纸给人类的生活带来了许多方便，但同时，人类对纸张的过度使用也给森林资源造成了极大的不良影响。大家知道，大面积的森林可以涵养水源，防止水士流失，净化空气，森林是制造氧气的“工厂”，森林能够吸收有害物质，森林能够保持水土。可见，节约每一张纸，对保护地球环境至关重要。

A piece of paper from why and come? Raw material for paper is mainly composed of bark and other plant fibers "change". A tree often require long years, decades to be human use. But sometimes people are unkind, chain saws, decades old growth trees crashing to the ground. The wood, was shipped to the paper mill, turned into a sheet of paper. The paper gives human life has brought a lot of convenience, but at the same time, the paper also human excessive use of forest resources caused great negative impact. As we all know, a large area of the forest can conserve water sources, prevent soil and water loss, purify the air, forest oxygen is produced "factory", forest can absorb harmful substances, soil and water conservation forest can. Visible, saving every piece of paper, is essential to protect the earth's environment.
