保護自然資源Natural Resources
Nature has provided us with many kinds of resources. All most everything we use in our everyday life comes from Nature. The food we eat, the water we drink, the clothes we wear, the concrete and bricks to build our houses, the materials to make bikes we ride, etc, all come originally from Nature.
大自然給我們提供了各種資源。我們日常生活中幾乎所有的東西都來自大自然。我們吃的糧，喝的水，穿的衣，建房用的水泥、磚，生產自行車用的材料等，都來源于大自然。
People have been making use of these natural supplies for thousands of years. With the development of technology and the increase of the population, the amount and range of mate rials taken has increased. It is estimated that this tread will continue in the years to come.
人們對大自然的利用有幾千年的歷史。隨著技術的進步，人口的增加，自然資源的用量和范圍都急劇增加。據估計這種趨勢將與日俱增。
However, natural resouces are not in exhaustible. Some resources are already nearly used up. For example, the end of the world's fuel is already within sight. Such an essential daily item as water is in short supply in many parts of the world. We can no longer thoughtlessly use the many resources provided by. Nature. We must learn to conserve what remains.
然而，自然資源并非取之不盡，用之不竭。有些資源幾乎已接近枯竭。例如，燃料資源匱乏已近在眼前。許多地方日常生活所必需的水已經供不應求。我們已不能再不加思索地使用大自然所賜予我們的資源了。我們必須學會保存那些剩余的資源。
