Explain how a natural ecosystem works.An Ecosystem at Work45Unit Three Endangered Species vs. Human NeedsText123Endangered Species vs. Human Needsby Martha Grace LowThe rate of species dying out is increasing dramatically. It is estimated that 27,000 species become extinct each year, about 3 an hour. Since 1996, scientists calculated that 124 types ofamphibians(两栖动物), 1,108 types of birds, 734 types of fish, 1,096 types of mammals, and 253 types of reptiles became endangered. These statistical figures also applyto plants. Once these species become extinct, they will never be seen on Earth again.What caused them to be endangered? Should human beings reflect on their actions?Could we do anything to benefit the future of humanity and all life on Earth?Read the following article taken from Martha Grace Low’s book Thresholds inReading published by Heinle & Heinle Publishers and find the answers to these questions.The most famous endangered species on earth were the dinosaurs. Theydied out in one of five “great extinctions” that have occurred in the millions of years since life began on this planet — periods in which, for natural causes, a large percentage of the species that existed simply disappeared. We are now in the middle of a sixth great extinction, but this one has been caused by human activity. Consequently, the importance of preserving species is a popular topic today, particularly in the industrialized world.But no discussion of endangered species is complete without anexamination of the reasons behind its causes, which are human needs. InAfrica, where the world’s population is growing the fastest, fore sts are shrinking as people clear lands for homes and farms and cut wood for fuel. Herds ofgoats and sheep eat the vegetation, leaving the bare soil to be carried away by wind and water. Humans kill wildlife to protect their crops, and may also killthem for the illegal trade in ivory, rhinoceros horns, furs. In Latin America and Southeast Asia, rainforests are cleared for farmlands and for fuel and timber.The loss of the forest endangers many species of plants and destroys manyanimals’ habitats, or natural homes. And in the oceans, fish supplies have been greatly reduced by overfishing and by pollution.Humans want to survive just as every other species does. We need food,shelter, and a place to rear our young. So how do our activities endanger other species? Specifically, there are three major ways. We kill off animals directlyin some cases. We may want their meat, bones, skins, tusks, horns, or feathers;or we may want to protect our crops and livestock from them. By overhunting,Euro-Americans endangered the buffalo in North America, and in thenineteenth century hunters drove to extinction the passenger pigeon1, which1 passenger pigeon: once the most abundant bird in the early part of the 19th century, lived in huge flocks in eastern NorthAmerica. It became extinct when the last known representative of the species —named Martha —died in the Cincinnati Zoo onSeptember 1, 1914. 旅鸽46新视角研究生英语读说写678was probably the most populous bird species that have ever lived.Another way that we endanger native life-forms is by introducing foreignspecies into their habitat. A prime example of this was the introduction ofEuropean rabbits into Australia, where they multiplied until they endangeredthe native species of grazing animals by eating all the vegetation. This becamea terrible problem that has finally been brought under some control, though not completely solved.The most common way that we endanger other species is by destroyingtheir natural habitats. We do this when we cut down forests, clear land forcrops, build towns, dam rivers, drain swamplands of water and then fill themwith dirt for construction, and when we pollute the air, the water, the soil. Most species are habitat-specific; that is, they depend on the particular offerings ofa specific environment, and they cannot simply move to the next province orstate and adapt as we can. The greatest diversity of life-formson our planet are found in the tropical rainforests, yet they are disappearing faster than any other habitat — at the rate of about 50 million acres (20 million hectares) per year.The loss of the rainforest would mean the loss of most of the species that maketheir homes in them.But so what? The majority of the animal species on earth are insects andworms anyway, and how important are they to us? And tiny populations oftropical plants —the world is covered with vegetation, so what difference doesit make, how many kinds there are?Many people’s answer is that every life-form has a right to exist, and thatno other reason is needed for preserving it. A more common reason is thebeauty of many species. Certain species also provide humans with economicvalue. But scientists identify two additional reasons which may not be obviousto most of us.One of these reasons is that each life-form occupies a special place within its ecosystem — that is, its community of plant and animal life, in combination withthe nonliving components of its environment such as the climate, soil, water, andair. For instance, within a forest the larger trees drop off little twigs and debris, making a layer that holds water in the soil for other plants to use. The roots hold the soil and prevent it fromwashing away in rainstorms. Whether living or dead,the tree provides shelter for animals and birds and food for insects. As the deadtree rots away, it enriches the soil of the forest floor, enabling other plants to spring up in its place. Such large trees are an example of what we call keystone species2; if they disappeared from their ecosystem, the consequences would befelt throughout the community of other species living in the forest. “The loss of a keystone species is like a drill accidentally striking a powerline,” says biologist Edward Wilson of Harvard University3. “It causes lights to go out all over.” During the current sixth great extinction, three species of life-forms are dying out every52 keystone species: a species whose presence impacts many other members of the ecosystem 关键物种3 Harvard University: oldest institution of higher learning in the United States and widely considered one of the most prestigious.Founded in 1636 in Cambridge, Mass., it was named Harvard College for a Puritan minister, John Harvard (1607–1638), who bequeathed to the school his books and half of his estate. 哈佛大学447Unit Three Endangered Species vs. Human Needshour, or 74 per day, which equals 27,000 each year. Some of these —and we don’t even know which ones — are undoubtedly keystone species.Natural ecosystems are characterized by their biodiversity,which meansthat a good variety of plant and animal life are present there. In many partsof today’s world, humans have replaced naturally diverse environments with monocultures, in which only one species lives — one that we humans value.A prime example in forested regions of the world is the monocultural “treefarms” that have been planted after the original forests have been cut down. The character of these tree farms is very different from that of the original forests.In the case of forests, another extremely important reason for preservingspecies is illustrated by the Pacific yew tree4, which people used to cut downand never replant because they thought it had no particular value. But recentl y medical researches discovered that a substance called taxol, produced naturallyin the bark of this tree, is an effective medication for treating certain kinds of cancer. Suddenly harvesters began flocking to the forests of the North AmericanPacific Northwest5 in search of this tree. If it had become extinct before its value had been discovered, many cancer patients would have died needlessly.Now, consider for a moment that there are around 1.6 million species thatwe have identified on earth (plus unco unted others that we haven’t identified),and most of them have never been studied to see whether they might be ableto provide us with food or medicine. About 15 percent of all our medicinesare derived from tropical plants, but we have been able to test only about 10percent of the plants that we know about, and have intensively studied lessthan 1 percent. Of the 74 species dying out each day, many of them are tropicalplants from the rainforests. In most cases, we don’t even know the value of whatwe are losing.If we turn from medicines to food sources, we find that over 50 percent oftoday’s global food supply consists of just three grains —wheat, rice, and corn.If climatic changes or a plant disease suddenly threatened one of these grains,many people would starve unless we could find another species to strengthen orreplace it. It is dangerous to be so dependent on such a small number of species.We need to preserve a wider variety of food species.Finally, a very important reason for preserving forestland is that plantsproduce the oxygen that animals (like us) breathe, and forests produce moreof the world’s oxygen than any other environment. Forests also make the airmore humid, producing rain; and the loss of forests leads to the process ofdesertification —the creation of deserts where little will grow.Many methods of protecting endangered species are being practiced indifferent parts of the globe. Legislation is a common method: passing lawsagainst killing endangered species or destroying their habitat. Worldwide, over1,200 parks and preserves have been set aside in which wildlife are protected.And certain endangered species are being raised in captivity for later release12131410114 the Pacific yew tree: found in the ancient forests of the Pacific Northwest 太平洋紫杉5 the North American Pacific Northwest: a 400 mile corridor with eight million residents stretches from Eugene, Oregon, throughSeattle, Washington to Vancouver, B.C., Canada948新视角研究生英语读说写into their wild habitats.An organization called the World Wildlife Fund6 recommends nine differentmethods that can be effective in protecting endangeredspecies. They are:1) Protect habitat2) Protect individual species3) Promote ecologically sound development4) Support scientific investigation5) Educate the public6) Train local wildlife professionals7) Encourage countries to design, fund, and carry out effective conservationactivities8) Monitor the international wildlife trade9) Influence public opinion and the policies of governments and privateinstitutions.Only time will tell how effective these attempts will be in slowing thespeed of the current great extinction. And the most important factor in this controversy is the demands of a growing human population for naturalresources and living space to serve its own needs.endanger /In9deIndZ5(r)/ v. cause danger to sb/sth, put in danger 危害，使遭到危险dinosaur /9daIn5sO:(r)/ n. 恐龙extinction /Ik9stIOEkSFn/ n. death or destruction of all members 灭绝preserve /prI9z?:v/ v. keep or maintain sth in an unchanged or perfect condition 保护n. a place where game or fish is protected and kept for private h unting orshooting 专供私人行猎或捕鱼的保护区vegetation /8vedZI9teISFn/ n. plants in general 植物(总称)ivory /9aIvFrI/ n. 象牙rhinoceros /raI9nás5r5s/ n. 犀牛rainforest /9reIn9fO:rIst/ n. thick evergreen forest in tropical regions with heavy rainfall 雨林(热带地区多雨的茂密常绿森林)habitat /9h{bIt{t/ n. natural environment of an animal or a plant (动物或植物的) 自然环境；栖息地tusk /t?sk/ n.

It is true that ever since we human beings inhabited the earth, we have been making all kinds of changes to nature. We clear lands for homes, cut wood for fuel, kill animals for meat, and dig coals for energy. As a result, nature has been badly encroached owing to our activities. But have we human beings done anything that benefits the nature and should be encouraged further? Give specific examples to justify your answer.3. The text says “every life-form has a right to exist” and that “each life-form occupies aspecial place within its ecosystem.” Do you agree with the two statements? Shouldwe protect all life-forms on Earth or let some die out? What about mosquitoes, flies, cockroaches and slugs? Should we kill them off?IV. Reading and RecitingA.
