Save the Forests

　　These days we often talk about the importance of our natural resources. In many countries they are disappearing at a rapid rate and environmentalists are urging people everywhere to protect their air， water， forests， wildlife， and so on. It is difficult to choose just one natural resource to save， but in my opinion， saving the forests should be the top priority. First of all， forests help to preserve other natural resources such as water， air， and animals. Without forests， the land cannot hold water as well. This means that in a heavy rain hillsides will collapse， causing great damage. Not only that， but without the protection of trees， the nutrient-rich topsoil will be washed away and nothing will be able to grow on the land. Trees also help to clean the air by absorbing carbon dioxide and producing oxygen. And， of course， forests are the natural habitat of many wild animals. Without them， these animals will not be able to survive. Another reason to preserve our forests is that large numbers of trees can help to mitigate the greenhouse effect by absorbing solar radiation. And finally， forests are a place where people can get close to nature， and if they learn to love nature， they will want to preserve all the earth's natural resources. All of the earth's natural resources are important， and we should all work to save them. The reason that I choose the forests as most important is because they help us in so many ways. By saving the forests， I believe we can save the planet.

　　拯救森林

　　如今，我们经常讨论天然资源的重要性。在许多国家，天然资源正在快速消失中。环保人士向全世界的人呼吁要保护空气、水、森林、野生动植物等资源。只选一样资源加以保护是很困难的，但依我之见，应该要优先考虑拯救森林。

　　首先，森林有助于保存其他的天然资源，比如水、空气和动物。如果没有森林，土壤就无法涵养水分。这意味着下大雨的时候，山坡会崩塌，造成极大的损害。不仅如此，如果没有树木的保护，富含养分的表土层就会被冲刷掉，土地就长不出任何东西。树木还会吸收二氧化碳，制造氧气，有助于净化空气。而且森林是很多野生动物的自然栖息地，如果没有森林，这些动物将无法生存。另外一个要保护森林的理由是，大量的树木可以吸收太阳辐射，以此缓和温室效应的影响。最后一点，森林是人类可以接近大自然的地方，如果人类学会爱护大自然，就会想保存地球上所有的天然资源。

　　地球上所有的天然资源都很重要，我们应该共同努力去拯救它们。我选择森林为最重要的资源，是因为森林很多方面都对我们有益。通过拯救森林，我相信我们也能够拯救地球。
