Unit 6　Nurturing nature 　　The only planet that supports life in the universe is our planet, the Earth. An important aspect of this planet is the existence of the rich variety of natural resources like soil, water, forests and wildlife. These are valuable resources which need to be protected in order to maintain the ecological balance in nature. On the contrary, human beings are overusing these resources, which has led to several harmful effects on the environment. The ecological balance between living things is under threat. It is a matter of great concern as all creatures are dependent on each other. If a species of animal becomes extinct, this would in turn lead to chains of extinction. A biological explanation with regard to “chains of extinction” refers to species of animals that are linked with each other and are becoming extinct. When no single member of a species is left to create young ones of its own kind, extinction becomes certain. Here’s an example to show how all creatures are related to each other. Birds feed off many parasitic arthropods(寄生节肢动物) which are found on hippopotamuses(河马). So if the hippopotamuses die, the birds will become extinct too. This would further lead to destruction as the species that are dependent on the birds will also be badly affected. Actually everything that exists in nature is dependent and nothing can survive alone. If any of the species go missing, the whole chain will be broken and go out of control. So for a living thing to survive, it must allow other living things to survive. The result is a complete balance in nature. Already 97% of species that lived on the Earth are now extinct. Therefore, there is an urgent need to protect the wildlife and their habitat properly and wisely, which is protecting human beings in fact. 【主题词句背诵】 1.on the contrary 相反,反之 2.overuse v. 过度使用 3.be under threat 受到威胁 4.feed off 以……为食 5.go out of control 失去控制 6.These are valuable resources which need to be protected in order to maintain the ecological balance in nature.
