Unit 4 Wildlife Protection导读：大自然是一个完整的生物链，人和动物的和谐相处会使我们所生活的环境更加美好，保持生态平衡是我们义不容辞的责任，对此你的观点如何呢？With rapid extinction of many wild species, more and more people come to realize the great significance of wildlife protection. We have to understand the problem in a new light that we protect ourselves through protecting wildlife. On the one hand, any species of wildlife, as a critical joint of the ecological chain, helps to establish the ecological balance. If one species becomes extinct, it will disappear forever. What is more, it will inevitably result in the extinction of a chain of wildlife and the disruption of the ecological balance. Unpredictable disasters may occur. On the other hand, with the development of modern science and technology, man is just beginning to learn about wildlife. For example, if wild rubber trees had been extinct two centuries ago, there would be no auto industry today. Moreover wildlife preserves unknown genetic codes, which may turn out to be a vital importance and free human beings from fatal diseases and natural disasters in the future. It is imperative for us to protect wildlife right now before it is too late, because man has already polluted the environment seriously and threaten the existence of many wild species. Let's take action to protect wildlife. Learning to live in harmony with all wildlife is part of modern civilization. —From news. iciba. com 请根据语义及提示写出单词 1.
