Nowadays,leaders the world over are busy mapping out blueprints for a new age withenvironmental protection high on their agenda. Sustainable development hits headlines almostevery day. It is of utmost importance to restore the harmonious balance between man andnature,given the damage we've already done to it.

　　First of all, we must realize that man and nature are interactive.To begin with, we deriveeverything fromnature. Among other things,I'm sure you've all tasted natural produce that isotherwise known as green food. And you must have noticed that nearly all beautifying productsboast of being natural creams,natural lotions or natural gels. For man,nature has an irresistibleappeal.

　　But on the other hand we must also realize that nature can be unruly.Nature is indeed like ariddle,some areas of which are beyond the reach of science and technology,at least in theforeseeable future. Nevertheless,the advancement of science and technology will stillcharacterize the next millennium. The coming new age will provide many opportunities,but itwill be likewise run of challenges. For instance,United Nations'demographers predict that globalpopulation could soar from its current 5.9 billion to as many as 11.2 billion by 2050.This willaggravate the current scarcity of natural resources caused by environmentaldegradation.More conflicts over this scarcity may occur with the ghost of nuclear wars alwayshiding in the background. To prevent this nightmare from coming true,governments need towork closely with each other and back up their verbal commitment by actions. However, it isnot enough only to ask what governments can do toachieve the harmony between man andnature. We must ask ourselves what we as individuals can do.

　　Can we all be economical with food,water,electricity or other resources? Can we,or rather,somegreedy ones among us,stop making rare plants and animals into delicious dishes? Can we stopusing the unrecyclable style of lunch boxes? If not,one day they may bury us in an ocean ofwhite rubbish.After all,the earth is not a dustbin;it's our common home.

　　如今世界各地的領導人都在忙于規劃新時代的藍圖，在這個時代，環境保護是他們日程表上優先考慮的項目。幾乎每天都有關于可持續發展的報道。考慮到我們人類已經給大自然造成了巨大傷害，恢復人類與自然的和諧與平衡就至關重要了。

　　首先，我們必須明白，人與自然是相互作用的。本來，我們的一切都來自于大自然。[1]別的不說，我敢說你們都曾經品嘗過自然生長的農產品，它們又被稱作“綠色食品”。[2]你們也一是注意到，幾乎所有美容產品都標榜是天然面霜、天然乳液或者天然膠。對人類來說，自然具有無法抗拒的魅力。

　　可是另一方面，我們一定也要認識到，大自然是無法駕馭的。大自然確實像是一個謎，有些領域是科學與技術鞭長莫及的，至少在可以預見的未來都是如此。[3]然而，科技的進步依然將會是下一個千年的主要特征。即將到來的新時代將會提供許多機會，但同樣也會帶來一連串的挑戰。舉例來說，聯合國人口統計學家預計，[4]全球人口將會急劇增加，從目前的59億增加到2050年的112億。這會使目前因環境惡化帶來的自然資源匱乏的問題更加嚴重。資源匱缺將導致更多的沖突，核戰爭的陰影總是揮之不去。為了防止這種夢魘變成現實，各國政府需要緊密地相互合作。以實際行動支持他們口頭做出的承諾。然而，要獲得人與自然的和諧，僅僅要求政府采取行動是不夠的。我們必須自問，我們每個人都能夠做些什么。

　　我們能不能節約使用糧食、水電以及其他資源?我們，或者更確切地說，我們當中那些貪心不足的人們，能不能夠不再把珍稀動植物當作美味? [5]我們能不能停止使用不可回收利用的午餐盒?如果不能的話，總有一天我們會被掩埋在白色垃圾的海洋里。畢竟，地球不是個垃圾桶，它是我們共同的家園。
