Amazon Rainforest

  Biodiversity is vital for many reasons, one of which is medicine. Many drugs that we use to cure illness and fight disease are made from plants in the rainforests. That is why scientists always do tests on plants that are newly found there. If the rainforests keep disappearing, we might lose the chance to find cures for certain diseases. Aside from medicine, there is the beauty of the rainforests and the creatures that live there. When the rainforests are gone, they will be gone forever. The same goes for plants and animals. Those that become extinct will never be seen again.

  The millions and millions of trees and plants in the rainforests help to clean carbon dioxide1 out of the air. This reduces air pollution and helps keep the Earth clean. However, the life of the Amazon rainforest is being seriously threatened. Climate change2 is one problem that makes it harder and harder for the rainforest to survive. Another is farming3. People have been cutting down the trees to clear the land so that they can use it for farming. Deforestation4 causes great damage to rainforests. Although it is important that people can grow food on farms, it is equally important to save the Amazon rainforest. Researchers believe that within 20 years, 40 percent of the current Amazon rainforest will be lost forever. Therefore, we should make every effort to protect this natural treasure before it is too late.

  生物多樣性之所以重要有很多原因,其一便是醫療用藥。許多我們現在用來治療疾病及對抗病魔的藥物皆由雨林中的植物所製成。這就是為何科學家總是在測試雨林中最新發現的植物。如果雨林持續消失,我們就可能會失去找到某些疾病療法的機會。除了藥物的研發,雨林之美以及生活於其中的動物也將受到影響。雨林一旦消失,它們將不復存在。同樣道理也適用於動植物。那些絕種的動植物將無法再親眼見到。

  雨林中數以百萬的樹木及植物有助於清除空氣中的二氧化碳。這不僅減少了空氣污染,也協助維持地球的清淨。然而,亞馬遜雨林的生命卻正遭受嚴重的威脅。氣候變遷是一大問題,它使得雨林越來越難以存活。另一原因則是農牧業。人們不斷砍伐樹木以製造空地,好讓他們能用來經營農牧。林木的濫墾濫伐會對雨林造成重大傷害。人們種植或飼養食物固然重要,但保護亞馬遜雨林也同樣要緊。研究學者認為在二十年內,現存的亞馬遜雨林有百分之四十將永遠消失。因此,我們應該在為時已晚之前,盡全力來保護這座大自然的瑰寶。
