高级英语下lesson 12 课文翻译

《高级英语》课文逐句翻译（12）我为什么写作Lesson 12：Why I Write从很小的时候，大概五、六岁，我知道长大以后将成为一个作家。

From a very early age，perhaps the age of five or six，I knew that when I grew up I should be a writer.从15到24岁的这段时间里，我试图打消这个念头，可总觉得这样做是在戕害我的天性，认为我迟早会坐下来伏案著书。

Between the ages of about seventeen and twenty-four I tried to adandon this idea，but I did so with the consciousness that I was outraging my true nature and that sooner or later I should have to settle down and write books.三个孩子中，我是老二。

老大和老三与我相隔五岁。

8岁以前，我很少见到我爸爸。

由于这个以及其他一些缘故，我的性格有些孤僻。

我的举止言谈逐渐变得很不讨人喜欢，这使我在上学期间几乎没有什么朋友。

I was the middle child of three，but there was a gap of five years on either side，and I barely saw my father before I was eight- For this and other reasons I was somewhat lonely，and I soon developed disagreeable mannerisms which made me unpopular throughout my schooldays.我像一般孤僻的孩子一样，喜欢凭空编造各种故事，和想像的人谈话。

全国高等教育自学考试指定教材英语专业（本科段）高级英语（下）王家湘课文翻译Lesson OneThe Company in Which I Work我工作的公司约瑟夫·海勒我工作的公司里，每个人都至少害怕一个人。

职位越低，所惧怕的人越多。

所有的人都害怕那十二位顶层上司，他们帮助创建了这个公司，而且现在仍然大权在握。

所有这十二位都已经上了年纪，而且岁月的沧桑和对成功的执著追求使他们心力交瘁。

他们中很多人在这儿干了一辈子。

当我在大厅里遇见他们时，他们看上去非常友善、沉稳而心满意足，而且他们与别人一起乘坐公共电梯时又总是彬彬有礼、沉默不语。

他们不再努力工作。

他们主持会议，决定别人的晋升，任凭别人在准备发布的通告中使用他们的名字，没有人知道谁真正经营这家公司（甚至连人们认为现在经营着这家公司的那些人都不知道），然而公司的确在运转。

在平常的工作日里，我很害怕杰克·格林，这是因为我所在的部门属于他的部门，而杰克·格林是我的上司。

格林害怕我则是因为我的部门的绝大部分工作是为销售部所做的，而销售部比他的部门更重要，而且同他相比，我与迪·卡葛勒以及销售部的其他人员的关系更加密切。

格林偶尔也对我不信任，他有时会向我表示他希望我的部门的每一项工作在其他部门知道前要先让他知道。

我知道这不是他真正的意思，他自己的工作非常忙，根本就无暇顾及我们所有的工作。

我会将大部分工作绕过格林并直接交给需要它们的人，而不愿意占他的时间。

毕竟我们部门绝大部分工作只是微不足道的。

但是每当其他部门赞扬我们部门的工作时，格林就会变得不安，如果他从未看见或听到过的话，就更是恼羞成怒。

在我的部门里，有六个人害怕我，其中一个小秘书害怕我们所有的人。

有一个为我工作的人，他对任何人都毫不惧怕，甚至连我也不怕，我真想尽快把他解雇掉，然而我害怕他……公司里非常惧怕大多数人的人是销售人员，他们都生活和工作在极大压力之下，当情况不好时，对销售人员来说就会更糟。

Lesson 3 Ships in the DesertShips in the DesertAL Gore1. I was standing in the sun on the hot steel deck of a fishing ship capableof processing a fifty-ton catch on a good day. But it wasn' t a good day. We were anchored in what used to be the most productive fishing site in all of central Asia, but as I looked out over the bow , the prospects of a good catch looked bleak. Where there should have been gentle blue-green waves lapping against the side of the ship, there was nothing but hot dry sand – as far as I could see in all directions. The other ships of the fleet were also at rest in the sand, scattered in the dunes that stretched all the way to the horizon . Ten year s ago the Aral was the fourth-largest inland sea in the world, comparable to the largest of North America's Great Lakes. Now it is disappearing because the water that used to feed it has been diverted in an ill-considered irrigation scheme to grow cotton In the user t. The new shoreline was almost forty kilometers across the sand from where the fishing fleet was now permanently docked. Meanwhile, in the nearby town of Muynak the people were still canning fish – brought not from the Aral Sea but shipped by rail through Siberia from the Pacific Ocean, more than a thousand miles away.2. My search for the underlying causes of the environmental crisis has led me to travel around the world to examine and study many of these images of destruction. At the very bottom of the earth, high in the Trans-Antarctic Mountains, with the sun glaring at midnight through a hole in the sky, I stood in the unbelievable coldness and talked with a scientist in the late tall of 1988 about the tunnel he was digging through time. Slipping his parka back to reveal a badly burned face that was cracked and peeling, he pointed to the annual layers of ice in a core sample dug from the glacier on which we were standing. He moved his finger back in time to the ice of two decades ago. "Here's where the U. S Congress passed the Clean Air Act, ” he said. At the bottom of the world, two continents away from Washington, D. C., even a small reduction in one country's emissions had changed the amount of pollution found in the remotest end least accessible place on earth.3. But the most significant change thus far in the earth' s atmosphere is the one that began with the industrial r evolution early in the last century and has picked up speed ever since. Industry meant coal, and later oil, and we began to burn lots of it –bringing rising levels of carbon dioxide (CO2) , with its ability to trap more heat in the atmosphere and slowly warm the earth. Fewer than a hundred yards from the South Pole, upwind from the ice runway where the ski plane lands and keeps its engines running to prevent the metal parts from freeze-locking together, scientists monitor the air sever al times ever y day to chart the course of that inexorable change. During my visit, I watched one scientist draw the results of that day's measurements, pushing the end of a steep line still higher on the graph. He told me how easy it is –there at the end of the earth –to see that this enormous change in the global atmosphere is still picking up speed.4. Two and a half years later I slept under the midnight sun at the other end of our planet, in a small tent pitched on a twelve-toot-thick slab of ice floating in the frigid Arctic Ocean. After a hearty breakfast, my companions and I traveled by snowmobiles a few miles farther north to a rendezvous point where the ice was thinner – only three and a half feet thick –and a nuclear submarine hovered in the water below. After it crashed through the ice, took on its new passengers, and resubmerged, I talked with scientists who were trying to measure more accurately the thickness of the polar ice cap, which many believe is thinning as a re-suit of global warming. I had just negotiated an agreement between ice scientists and the U. S. Navy to secure the re-lease of previously top secret data from submarine sonar tracks, data that could help them learn what is happening to the north polar cap. Now, I wanted to see the pole it-self, and some eight hours after we met the submarine, we were crashing through that ice, surfacing, and then I was standing in an eerily beautiful snowcape, windswept and sparkling white, with the horizon defined by little hummocks, or "pressure ridges " of ice that are pushed up like tiny mountain ranges when separate sheets collide. But here too, CD, levels are rising just as rapidly, and ultimately temperature will rise with them –indeed, global warming is expected to push temperatures up much more rapidly in the polar regions than in the rest of the world. As the polar air warms, the ice her e will thin; and since the polar cap plays such a crucial role in the world's weather system, the consequences of a thinning cap could be disastrous.5. Considering such scenarios is not a purely speculative exercise. Six months after I returned from the North Pole, a team of scientists reported dramatic changes in the pattern of ice distribution in the Arctic, and a second team reported a still controversialclaim (which a variety of data now suggest) that, over all, the north polar cap has thinned by 2 per cent in just the last decade. Moreover, scientists established several years ago that in many land areas north of the Arctic Circle, the spring snowmelt now comes earlier every year, and deep in the tundra below, the temperature e of the earth is steadily rising.6. As it happens, some of the most disturbing images of environmental destruction can be found exactly halfway between the North and South poles –precisely at the equator in Brazil –where billowing clouds of smoke regularly black-en the sky above the immense but now threatened Amazon rain forest. Acre by acre, the rain forest is being burned to create fast pasture for fast-food beef; as I learned when I went there in early 1989, the fires are set earlier and earlier in the dry season now, with more than one Tennessee's worth of rain forest being slashed and burned each year. According to our guide, the biologist Tom Lovejoy, there are more different species of birds in each square mile of the Amazon than exist in all of North America –which means we are silencing thousands of songs we have never even heard.7. But one doesn't have to travel around the world to wit-ness humankind's assault on the earth. Images that signal the distress of our global environment are nowcommonly seen almost anywhere. On some nights, in high northern latitudes, the sky itself offers another ghostly image that signals the loss of ecological balance now in progress. If the sky is clear after sunset -- and it you are watching from a place where pollution hasn't blotted out the night sky altogether -- you can sometimes see a strange kind of cloud high in the sky. This "noctilucent cloud" occasionally appears when the earth is first cloaked in the evening dark-ness; shimmering above us with a translucent whiteness, these clouds seem quite unnatural. And they should: noctilucent clouds have begun to appear more often because of a huge buildup of methane gas in the atmosphere. (Also called natural gas, methane is released from landfills , from coal mines and rice paddies, from billions of termites that swarm through the freshly cut forestland, from the burning of biomass and from a variety of other human activities. ) Even though noctilucent clouds were sometimes seen in the past., all this extra methane carries more water vapor into the upper atmosphere, where it condenses at much higher altitudes to form more clouds that the sun's rays still strike long after sunset has brought the beginning of night to the surface far beneath them.8. What should we feel toward these ghosts in the sky? Simple wonder or the mix of emotions we feel at the zoo? Perhaps we should feel awe for our own power: just as me n "ear tusks from elephants’ heads in such quantity as to threaten the beast with extinction, we are ripping matter from its place in the earth in such volume as to upset the balance between daylight and darkness. In the process, we are once again adding to the threat of global warming, be-cause methane has been one of the fastest-growing green-house gases, and is third only to carbon dioxide and water vapor in total volume, changing the chemistry of the upper atmosphere. But, without even considering that threat, shouldn't it startle us that we have now put these clouds in the evening sky which glisten with a spectral light? Or have our eyes adjusted so completely to the bright lights of civilization that we can't see these clouds for what they are – a physical manifestation of the violent collision between human civilization and the earth?9. Even though it is sometimes hard to see their meaning, we have by now all witnessed surprising experiences that signal the damage from our assault on the environment --whether it's the new frequency of days when the temperature exceeds 100 degrees, the new speed with which the -un burns our skin, or the new constancy of public debate over what to do with growing mountains of waste. But our response to these signals is puzzling. Why haven't we launched a massive effort to save our environment? To come at the question another way' Why do some images startle us into immediate action and focus our attention or ways to respond effectively? And why do other images, though sometimes equally dramatic, produce instead a Kin. of paralysis, focusing our attention not on ways to respond but rather on some convenient, less painful distraction?10. Still, there are so many distressing images of environ-mental destruction that sometimes it seems impossible to know how to absorb or comprehend them. Before considering the threats themselves, it may be helpful to classify them and thus begin to organize our thoughts and feelings so that we may be able to respond appropriately.11. A useful system comes from the military, which frequently places a conflictin one of three different categories, according to the theater in which it takes place. There are "local" skirmishes, "regional" battles, and "strategic" conflicts. This third category is reserved for struggles that can threaten a nation's survival and must be under stood in a global context.12. Environmental threats can be considered in the same way. For example, most instances of water pollution, air pollution, and illegal waste dumping are essentially local in nature. Problems like acid rain, the contamination of under-ground aquifers, and large oil spills are fundamentally regional. In both of these categories, there may be so many similar instances of particular local and regional problems occurring simultaneously all over the world that the patter n appears to be global, but the problems themselves are still not truly strategic because the operation of- the global environment is not affected and the survival of civilization is not at stake.13. However, a new class of environmental problems does affect the global ecological system, and these threats are fundamentally strategic. The 600 percent increase in the amount of chlorine in the atmosphere during the last forty years has taken place not just in those countries producing the chlorofluorocarbons responsible but in the air above every country, above Antarctica, above the North Pole and the Pacific Ocean – all the way from the surface of the earth to the top of the sky. The increased levels of chlorine disrupt the global process by which the earth regulates the amount of ultraviolet radiation from the sun that is allowed through the atmosphere to the surface; and it we let chlorine levels continue to increase, the radiation levels will al-so increase – to the point that all animal and plant life will face a new threat to their survival.14. Global warming is also a strategic threat. The concentration of carbon dioxide and other heat-absorbing molecules has increased by almost 25 per cent since World War II, posing a worldwide threat to the earth's ability to regulate the amount of heat from the sun retained in the atmosphere. This increase in heat seriously threatens the global climate equilibrium that determines the pattern of winds, rainfall, surface temperatures, ocean currents, and sea level. These in turn determine the distribution of vegetative and animal life on land and sea and have a great effect on the location and pattern of human societies.15. In other words, the entire relationship between humankind and the earth has been transformed because our civilization is suddenly capable of affecting the entire global environment, not just a particular area. All of us know that human civilization has usually had a large impact on the environment; to mention just one example, there is evidence that even in prehistoric times, vast areas were sometimes intentionally burned by people in their search for food. And in our own time we have reshaped a large part of the earth's surface with concrete in our cities and carefully tended rice paddies, pastures, wheat fields, and other croplands in the countryside. But these changes, while sometimes appearing to be pervasive , have, until recently, been relatively trivial factors in the global ecological sys-tem. Indeed, until our lifetime, it was always safe to assume that nothing we did or could do would have any lasting effect on the global environment. But it is precisely that assumption which must now be discarded so that we can think strategically about our new relationship to theenvironment.16. Human civilization is now the dominant cause of change in the global environment. Yet we resist this truth and find it hard to imagine that our effect on the earth must now be measured by the same yardstick used to calculate the strength of the moon's pull on the oceans or the force of the wind against the mountains. And it we are now capable of changing something so basic as the relationship between the earth and the sun, surely we must acknowledge a new responsibility to use that power wisely and with appropriate restraint. So far, however, We seem oblivious of the fragility of the earth's natural systems.17. This century has witnessed dramatic changes in two key factors that define the physical reality of our relation-ship to the earth: a sudden and startling surge in human population, with the addition of one China's worth of people every ten years, and a sudden acceleration of the scientific and technological revolution, which has allowed an almost unimaginable magnification of our power to affect the world around us by burning, cutting, digging, moving, and trans-forming the physical matter that makes up the earth.18. The surge in population is both a cause of the changed relationship and one of the clearest illustrations of how startling the change has been, especially when viewed in a historical context. From the emergence of modern humans 200 000 years ago until Julius Caesar's time, fewer than 250 million people walked on the face of the earth. When Christopher Columbus set sail for the New World 1500 years later, there were approximately 500 million people on earth. By the time Thomas Jefferson wrote the Declaration of Independence in 1776, the number had doubled again, to 1 billion. By midway through this century, at the end of World War II, the number had risen to just above 2 billion people.19. In other words, from the beginning of humanity's appearance on earth to 1945, it took more than ten thousand generations to reach a world population of 2 billion people. Now, in the course of one human lifetime -- mine -- the world population will increase from 2 to more than 9 million, and it is already more than halfway there.20. Like the population explosion, the scientific and technological revolution began to pick up speed slowly during the eighteenth century. And this ongoing revolution has also suddenly accelerated exponentially. For example, it is now an axiom in many fields of science that more new and important discoveries have taken place in the last ten years that. in the entire previous history of science. While no single discover y has had the kind of effect on our relationship to the earth that unclear weapons have had on our relationship to warfare, it is nevertheless true that taken together, they have completely transformed our cumulative ability to exploit the earth for sustenance -- making the consequences, of unrestrained exploitation every bit as unthinkable as the consequences of unrestrained nuclear war.21. Now that our relationship to the earth has changed so utterly, we have to see that change and understand its implications. Our challenge is to recognize that thestartling images of environmental destruction now occurring all over the world have much more in common than their ability to shock and awaken us. They are symptoms of an underlying problem broader in scope and more serious than any we have ever faced. Global warming, ozone depletion, the loss of living species, deforestation -- they all have a common cause: the new relationship between human civilization and the earth's natural balance.22. There are actually two aspects to this challenge. The first is to realize that our power to harm the earth can in-deed have global and even permanent effects. The second is to realize that the only way to understand our new role as a co-architect of nature is to see ourselves as part of a complex system that does not operate according to the same simple rules of cause and effect we are used to. The problem is not our effect on the environment so much as our relationship with the environment. As a result, any solution to the problem will require a careful assessment of that relationship as well as the complex interrelationship among factors within civilization and between them and the major natural components of the earth's ecological system.23. The strategic nature of the threat now posed by human civilization to the global environment and the strategic nature of the threat to human civilization now posed by changes in the global environment present us with a similar set of challenges and false hopes. Some argue that a new ultimate technology, whether nuclear power or genetic engineering, will solve the problem. Others hold that only a drastic reduction of our reliance on technology can improve the conditions of life -- a simplistic notion at best. But the real solution will be found in reinventing and finally healing the relationship between civilization and the earth. This can only be accomplished by undertaking a careful reassessment of all the factors that led to the relatively recent dramatic change in the relationship. The transformation of the way we relate to the earth will of course involve new technologies, but the key changes will involve new ways of thinking about the relationship itself.。

Lesson 12: Why I WriteFrom a very early age, perhaps the age of five or six, I knew that when I grew up I should be a writer.Between the ages of about seventeen and twenty-four I tried to abandon this idea, but I did so with the consciousness that I was outraging my true nature and that sooner or later I should have to settle down and write books.=During the age of 15 to 24, I attempted to give up this idea, but when I was doing so, I felt that it was ruining my essential quality and that I would engage in writing sooner or later.I was the middle child of three, but there was a gap of five years on either side, and I barely saw my father before I was eight- For this and other reasons I was somewhat lonely, and I soon developed disagreeable mannerisms which made me unpopular throughout my schooldays.=Among the three kids, I was the middle with the gap of five years to the rest of them. [ I was five years younger than my elder brother and five years older than my younger brother. ] Before I was eight, I seldom saw my father. I thus felt lonely for this and perhaps other unknown reasons. Hence, I was not agreeable to people due to my personality, which resulted in my unpopularity in schooldays. mannerism=A distinctive behavioral trait;习性：明显的行为特征；习性Somewhat=To some extent or degree; rather.相当：达到某种范围或程度；相当Develop=To bring into being gradually:逐渐形成：I had the lonely child's habit of making up stories and holding conversations with imaginary persons, and I think from the very start my literary ambitions were mixed up with the feeling of being isolated and undervalued.=Like every other child who felt lonely all the time, I enjoyed invented stories and talked to people that didn’t exist. From the very beginning, I suppose, my aspiration for writing was closely connected with the felling of being lonely and being slighted.I knew that I had a facility with words and a power of facing unpleasant facts, and I felt that this created a sort of private world in which I could get my own back for my failure=I was aware that I was capable of commanding words[ I had the natural ability to use words easily and well.] and confronting the dark sides of the reality, which, I assume, constructed a private space for me in which I could make up for my failure.. . As a very small child I used to imagine that I was, say, Robin Hood, and picture myself as the hero of thrilling adventures, but quite soon my "story" ceased to be narcissistic 【Excessive love or admiration of oneself.】in a crude 【Not carefully or completely made; rough. 】way and became more and more a mere description of what I was doing and the things I saw.=When I was very little, I always imagined me being the hero of exciting and horrifying adventures, such as Robin Hood, but before long, I stop such simpleself-admiration and began to put what I saw and what I was doing into my story.一连几分钟，我脑子里常会有类似这样的描述：“他推开门，走进屋，一缕黄昏的阳光，透过薄纱窗帘，斜照在桌上。

Lesson 1 摇滚歌星1972年6月的一天，芝加哥圆形剧场挤满了大汗淋漓、疯狂摇摆的人们。

滚石摇滚乐队的迈克•贾格尔正在台上演唱“午夜漫步人”。

演唱结束时评论家唐•赫克曼在现场。

他描述道：“贾格尔抓起一个半加仑的水罐沿舞台前沿边跑边把里面的水洒向前几排汗流浃背的听众。

听众们蜂拥般跟随着他跑，急切地希望能沾上几滴洗礼的圣水。

1973年12月下旬的一天，约1.4万名歌迷在华盛顿市外的首都中心剧场尖叫着，乱哄哄地拥向台前。

美国的恐怖歌星艾利丝•库珀的表演正接近尾声。

他表演的最后一幕是假装在断头台上结束自己的生命。

他的“头”落入一个草篮中。

“哎呀！”一个黑衣女孩子惊呼道：“啊!真是了不起，不是吗？”。

当时，14岁的迈克珀力也在场，但他的父母不在那里。

“他们觉得他恶心，恶心，恶心，”迈克说，“他们对我说，你怎么受得了那些？”1974年1月下旬的一天，在纽约州尤宁谷城拿骚体育场内，鲍勃•狄伦和“乐队”乐队正在为音乐会上要用的乐器调音。

馆外，摇滚歌迷克利斯•辛格在大雨中等待着入场。

“这是朝圣，”克利斯说，“我应该跪着爬进去。

”对于这一切好评及个人崇拜，你怎么看？当米克•贾格尔的崇拜者们把他视为上帝的最高代表或是一个神时，你是赞成还是反对？你也和克利斯•辛格一样对鲍勃•狄伦怀有几乎是宗教般的崇敬吗？你认为他或狄伦是步入歧途吗？你也认为艾利丝•库珀令人恶心而拒不接受吗？难道你会莫名其妙地被这个奇怪的小丑吸引，原因就在于他表达出你最狂热的幻想？这些并不是闲谈。

有些社会学家认为对这些问题的回答可以充分说明你在想些什么以及社会在想些什么——也就是说，有关你和社会的态度。

社会学家欧文•霍洛威茨说：“音乐表现其时代。

” 霍洛威茨把摇滚乐的舞台视为某种辩论的论坛，一个各种思想交锋的场所。

他把它看作是一个美国社会努力为自己的感情及信仰不断重新进行解释的地方。

他说：“重新解释是一项只有青年人才能执行的任务。

只有他们才把创造与夸张、理性与运动、言语与声音、音乐与政治融为一体。

The LoonsMargarel LaurenceJust below Manawaka, where the Wachakwa River ran brown and noisy over the pebbles , the scrub oak and grey-green willow and chokecherry bushes grew in a dense thicket . In a clearing at the centre of the thicket stood the Tonnerre family's shack. The basis at this dwelling was a small square cabin made of poplar poles and chinked with mud, which had been built by Jules Tonnerre some fifty years before, when he came back from Batoche with a bullet in his thigh, the year that Riel was hung and the voices of the Metis entered their long silence. Jules had only intended to stay the winter in the Wachakwa Valley, but the family was still there in the thirties, when I was a child. As the Tonnerres had increased, their settlement had been added to, until the clearing at the foot of the town hill was a chaos of lean-tos, wooden packing cases, warped lumber, discarded car types, ramshackle chicken coops , tangled strands of barbed wire and rusty tin cans.The Tonnerres were French half breeds, and among themselves they spoke a patois that was neither Cree norFrench. Their English was broken and full of obscenities . They did not belong among the Cree of the Galloping Mountain reservation, further north, and they did not belong among the Scots-Irish and Ukrainians of Manawaka, either. They were, as my Grandmother MacLeod would have put it, neither flesh, fowl, nor good salt herring . When their men were not working at odd jobs or as section hands on the . R. they lived on relief. In the summers, one of the Tonnerre youngsters, with a face that seemed totally unfamiliar with laughter, would knock at the doors of the town's brick houses and offer for sale a lard -pail full of bruised wild strawberries, and if he got as much as a quarter he would grab the coin and run before the customer had time to change her mind. Sometimes old Jules, or his son Lazarus, would get mixed up in a Saturday-night brawl , and would hit out at whoever was nearest or howl drunkenly among the offended shoppers on Main Street, and then the Mountie would put them for the night in the barred cell underneath the Court House, and the next morning they would be quiet again.Piquette Tonnerre, the daughter of Lazarus, wasin my class at school. She was older than I, but she had failed several grades, perhaps because her attendance hadalways been sporadic and her interest in schoolwork negligible . Part of the reason she had missed a lot of school was that she had had tuberculosis of the bone, and had once spent many months in hospital. I knew this because my father was the doctor who had looked after her. Her sickness was almost the only thing I knew about her, however. Otherwise, she existed for me only as a vaguely embarrassing presence, with her hoarse voice and her clumsy limping walk and her grimy cotton dresses that were always miles too long. I was neither friendly nor unfriendly towards her. She dwelt and moved somewhere within my scope of vision, but I did not actually notice her very much until that peculiar summer when I was eleven."I don't know what to do about that kid." my father said at dinner one evening. "Piquette Tonnerre, I mean. The damn bone's flared up again. I've had her in hospital for quite a while now, and it's under control all right, but I hate like the dickens to send her home again.""Couldn't you explain to her mother that she has to rest a lot" my mother said."The mother's not there" my father replied. "She took offa few years back. Can't say I blame her. Piquette cooks for them, and she says Lazarus would never do anything for himself as long as she's there. Anyway, I don't think she'd take much care of herself, once she got back. She's only thirteen, after all. Beth, I was thinking—What about taking her up to Diamond Lake with us this summer A couple of months rest would give that bone a much better chance."My mother looked stunned."But Ewen -- what about Roddie and Vanessa""She's not contagious ," my father said. "And it would be company for Vanessa.""Oh dear," my mother said in distress, "I'll bet anything she has nits in her hair.""For Pete's sake," my father said crossly, "do you think Matron would let her stay in the hospital for all this time like that Don't be silly, Beth. "Grandmother MacLeod, her delicately featured face as rigid as a cameo , now brought her mauve -veined hands together as though she were about to begin prayer."Ewen, if that half breed youngster comes along to Diamond Lake, I'm not going," she announced. "I'll go to Morag's for the summer."I had trouble in stifling my urge to laugh, for my mother brightened visibly and quickly tried to hide it. If it came to a choice between Grandmother MacLeod and Piquette, Piquette would win hands down, nits or not. "It might be quite nice for you, at that," she mused. "You haven't seen Morag for over a year, and you might enjoy being in the city for a while. Well, Ewen dear, you do what you think best. If you think it would do Piquette some good, then we' II be glad to have her, as long as she behaves herself."So it happened that several weeks later, when we all piled into my father's old Nash, surrounded by suitcases and boxes of provisions and toys for my ten-month-old brother, Piquette was with us and Grandmother MacLeod, miraculously, was not. My father would only be staying at the cottage for a couple of weeks, for he had to get back to his practice, but the rest of us would stay at Diamond Lake until the end of August.Our cottage was not named, as many were, "Dew Drop Inn" or "Bide-a-Wee," or "Bonnie Doon”. The sign on the roadway bore in austere letters only our name, MacLeod. It was not a large cottage, but it was on the lakefront. You could look out the windows and see, through the filigree of the spruce trees, the water glistening greenly as the sun caught it. All around the cottage were ferns, and sharp-branched raspberry bushes, and moss that had grown over fallen tree trunks, If you looked carefully among the weeds and grass, you could find wild strawberry plants which were in white flower now and in another month would bear fruit, the fragrant globes hanging like miniature scarlet lanterns on the thin hairy stems. The two grey squirrels were still there, gossiping at us from the tall spruce beside the cottage, and by the end of the summer they would again be tame enough to take pieces of crust from my hands. The broad moose antlers that hung above the back door were a little more bleached and fissured after the winter, but otherwise everything was the same. I raced joyfully around my kingdom, greeting all the places I had not seen for a year. My brother, Roderick, who had not been born when we were here last summer, sat on the car rug in the sunshine andexamined a brown spruce cone, meticulously turning it round and round in his small and curious hands. My mother and father toted the luggage from car to cottage, exclaiming over how well the place had wintered, no broken windows, thank goodness, no apparent damage from storm felled branches or snow.Only after I had finished looking around did I notice Piquette. She was sitting on the swing her lame leg held stiffly out, and her other foot scuffing the ground as she swung slowly back and forth. Her long hair hung black and straight around her shoulders, and her broadcoarse-featured face bore no expression -- it was blank, as though she no longer dwelt within her own skull, as though she had gone elsewhere.I approached her very hesitantly."Want to come and play"Piquette looked at me with a sudden flash of scorn."I ain't a kid," she said.Wounded, I stamped angrily away, swearing I would notspeak to her for the rest of the summer. In the days that followed, however, Piquette began to interest me, and l began to want to interest her. My reasons did not appear bizarre to me. Unlikely as it may seem, I had only just realised that the Tonnerre family, whom I had always heard Called half breeds, were actually Indians, or as near as made no difference. My acquaintance with Indians was not expensive. I did not remember ever having seen a real Indian, and my new awareness that Piquette sprang from the people of Big Bear and Poundmaker, of Tecumseh, of the Iroquois who had eaten Father Brébeuf's heart--all this gave her an instant attraction in my eyes. I was devoted reader of Pauline Johnson at this age, and sometimes would orate aloud and in an exalted voice, West Wind, blow from your prairie nest, Blow from the mountains, blow from the west--and so on. It seemed to me that Piquette must be in some way a daughter of the forest, a kind of junior prophetess of the wilds, who might impart to me, if I took the right approach, some of the secrets which she undoubtedly knew --where the whippoorwill made her nest, how the coyote reared her young, or whatever it was that it said in Hiawatha.I set about gaining Piquette's trust. She was not allowed to go swimming, with her bad leg, but I managed to lure her down to the beach-- or rather, she came because there was nothing else to do. The water was always icy, for the lake was fed by springs, but I swam like a dog, thrashing my arms and legs around at such speed and with such an output of energy that I never grew cold. Finally, when I had enough, I came out and sat beside Piquette on the sand. When she saw me approaching, her hands squashed flat the sand castle she had been building, and she looked at me sullenly, without speaking."Do you like this place" I asked, after a while, intending to lead on from there into the question of forest lore .Piquette shrugged. "It's okay. Good as anywhere.""I love it, "1 said. "We come here every summer." "So what" Her voice was distant, and I glanced at her uncertainly, wondering what I could have said wrong."Do you want to come for a walk" I asked her. "We wouldn't need to go far. If you walk just around the pointthere, you come to a bay where great big reeds grow in the water, and all kinds of fish hang around there. Want to Come on."She shook her head."Your dad said I ain't supposed to do no more walking than I got to." I tried another line."I bet you know a lot about the woods and all that, eh" I began respectfully.Piquette looked at me from her large dark unsmiling eyes."I don't know what in hell you're talkin' about," she replied. "You nuts or somethin' If you mean where my old man, and me, and all them live, you better shut up, by Jesus, you hear"I was startled and my feelings were hurt, but I hada kind of dogged perseverance. I ignored her rebuff."You know something, Piquette There's loons here, on this lake. You can see their nests just up the shore there, behind those logs. At night, you can hear them even fromthe cottage, but it's better to listen from the beach. My dad says we should listen and try to remember how they sound, because in a few years when more cottages are built at Diamond Lake and more people come in, the loons will go away."Piquette was picking up stones and snail shells and then dropping them again."Who gives a good goddamn" she said.It became increasingly obvious that, as an Indian, Piquette was a dead loss. That evening I went out by myself, scrambling through the bushes that overhung the steep path, my feet slipping on the fallen spruce needles that covered the ground. When I reached the shore, I walked along the firm damp sand to the small pier that my father had built, and sat down there. I heard someone else crashing through the undergrowth and the bracken, and for a moment I thought Piquette had changed her mind, but it turned out to be my father. He sat beside me on the pier and we waited, without speaking.At night the lake was like black glass with a streakof amber which was the path of the moon. All around, the spruce trees grew tall and close-set, branches blackly sharp against the sky, which was lightened by a cold flickering of stars. Then the loons began their calling. They rose like phantom birds from the nests on the shore, and flew out onto the dark still surface of the water.No one can ever describe that ululating sound, the crying of the loons, and no one who has heard it can ever forget it. Plaintive , and yet with a quality of chilling mockery , those voices belonged to a world separated by aeon from our neat world of summer cottages and the lighted lamps of home."They must have sounded just like that," my father remarked, "before any person ever set foot here." Then he laughed. "You could say the same, of course, about sparrows or chipmunk, but somehow it only strikes you that way with the loons.""I know," I said.Neither of us suspected that this would be the last time we would ever sit here together on the shore, listening.We stayed for perhaps half an hour, and then we went back to the cottage. My mother was reading beside the fireplace. Piquette was looking at the burning birch log, and not doing anything."You should have come along," I said, although in fact I was glad she had not."Not me", Piquette said. "You wouldn’ catch me walkin' way down there jus' for a bunch of squawkin' birds."Piquette and I remained ill at ease with one another. felt I had somehow failed my father, but I did not know what was the matter, nor why she Would not or could not respond when I suggested exploring the woods or Playing house. I thought it was probably her slow and difficult walking that held her back. She stayed most of the time in the cottage with my mother, helping her with the dishes or with Roddie, but hardly ever talking. Then the Duncans arrived at their cottage, and I spent my days with Mavis, who was my best friend. I could not reach Piquette at all, and I soon lost interest in trying. But all that summer she remained as both a reproach and a mystery to me.That winter my father died of pneumonia, after less than a week's illness. For some time I saw nothing around me, being completely immersed in my own pain and my mother's. When I looked outward once more, I scarcely noticed that Piquette Tonnerre was no longer at school. I do not remember seeing her at all until four years later, one Saturday night when Mavis and I were having Cokes in the Regal Café. The jukebox was booming like tuneful thunder, and beside it, leaning lightly on its chrome and its rainbow glass, was a girl.Piquette must have been seventeen then, although she looked about twenty. I stared at her, astounded that anyone could have changed so much. Her face, so stolid and expressionless before, was animated now with a gaiety that was almost violent. She laughed and talked very loudly with the boys around her. Her lipstick was bright carmine, and her hair was cut Short and frizzily permed . She had not been pretty as a child, and she was not pretty now, for her features were still heavy and blunt. But her dark and slightly slanted eyes were beautiful, and her skin-tight skirt and orange sweater displayed to enviable advantage a soft and slender body.She saw me, and walked over. She teetered a little, but it was not due to her once-tubercular leg, for her limp was almost gone."Hi, Vanessa," Her voice still had the same hoarseness . "Long time no see, eh""Hi," I said "Where've you been keeping yourself, Piquette""Oh, I been around," she said. "I been away almost two years now. Been all over the place--Winnipeg, Regina, Saskatoon. Jesus, what I could tell you! I come back this summer, but I ain't stayin'. You kids go in to the dance""No," I said abruptly, for this was a sore point with me. I was fifteen, and thought I was old enough to go to the Saturday-night dances at the Flamingo. My mother, however, thought otherwise."Y'oughta come," Piquette said. "I never miss one. It's just about the on'y thing in this jerkwatertown that's any fun. Boy, you couldn' catch me stayin' here.I don' give a shit about this place. It stinks."She sat down beside me, and I caught the harsh over-sweetness of her perfume."Listen, you wanna know something, Vanessa" she confided , her voice only slightly blurred. "Your dad was the only person in Manawaka that ever done anything good to me."I nodded speechlessly. I was certain she was speaking the truth. I knew a little more than I had that summer at Diamond Lake, but I could not reach her now any more than I had then, I was ashamed, ashamed of my own timidity, the frightened tendency to look the other way. Yet I felt no real warmth towards her-- I only felt that I ought to, because of that distant summer and because my father had hoped she would be company for me, or perhaps that I would be for her, but it had not happened that way. At this moment, meeting her again, I had to admit that she repelled and embarrassed me, and I could not help despising theself-pity in her voice. I wished she would go away. I did not want to see her did not know what to say to her. It seemed that we had nothing to say to one another."I'll tell you something else," Piquette went on. "Allthe old bitches an' biddies in this town will sure be surprised. I'm gettin' married this fall -- my boy friend, he's an English fella, works in the stockyards in the city there, a very tall guy, got blond wavy hair. Gee, is he ever handsome. Got this real Hiroshima name. Alvin Gerald Cummings--some handle, eh They call him Al."For the merest instant, then I saw her. I really did see her, for the first and only time in all the years we had both lived in the same town. Her defiant face, momentarily, became unguarded and unmasked, and in her eyes there was a terrifying hope."Gee, Piquette --" I burst out awkwardly, "that's swell. That's really wonderful. Congratulations—good luck--I hope you'll be happy--"As l mouthed the conventional phrases, I could only guess how great her need must have been, that she had been forced to seek the very things she so bitterly rejected.When I was eighteen, I left Manawaka and went away to college. At the end of my first year, I came back home for the summer. I spent the first few days in talking non-stopwith my mother, as we exchanged all the news that somehow had not found its way into letters-- what had happened in my life and what had happened here in Manawaka while I was away. My mother searched her memory for events that concerned people I knew."Did I ever write you about Piquette Tonnerre, Vanessa" she asked one morning."No, I don't think so," I replied. "Last I heard of her, she was going to marry some guy in the city. Is she still there"My mother looked Hiroshima , and it was a moment before she spoke, as though she did not know how to express what she had to tell and wished she did not need to try."She's dead," she said at last. Then, as I stared at her, "Oh, Vanessa, when it happened, I couldn't help thinking of her as she was that summer--so sullen and gauche and badly dressed. I couldn't help wondering if we could have done something more at that time--but what could we do She used to be around in the cottage there with me all day, and honestly it was all I could do to get a word outof her. She didn't even talk to your father very much, although I think she liked him in her way.""What happened" I asked."Either her husband left her, or she left him," my mother said. "I don't know which. Anyway, she came back here with two youngsters, both only babies--they must have been born very close together. She kept house, I guess, for Lazarus and her brothers, down in the valley there, in the old Tonnerre place. I used to see her on the street sometimes, but she never spoke to me. She'd put on an awful lot of weight, and she looked a mess, to tell you the truth, a real slattern , dressed any old how. She was up in court a couple of times--drunk and disorderly, of course. One Saturday night last winter, during the coldest weather, Piquette was alone in the shack with the children. The Tonnerres made home brew all the time, so I've heard, and Lazarus said later she'd been drinking most of the day when he and the boys went out that evening. They had an old woodstove there--you know the kind, with exposed pipes. The shack caught fire. Piquette didn't get out, and neither did the children."I did not say anything. As so often with Piquette, there did not seem to be anything to say. There was a kind of silence around the image in my mind of the fire and the snow, and I wished I could put from my memory the look that I had seen once in Piquette's eyes.I went up to Diamond Lake for a few days that summer, with Mavis and her family. The MacLeod cottage had been sold after my father's death, and I did not even go to look at it, not wanting to witness my long-ago kingdom possessed now by strangers. But one evening I went clown to the shore by myself.The small pier which my father had built was gone, and in its place there was a large and solid pier built by the government, for Galloping Mountain was now a national park, and Diamond Lake had been re-named Lake Wapakata, for it was felt that an Indian name would have a greater appeal to tourists. The one store had become several dozen, and the settlement had all the attributes of a flourishing resort--hotels, a dance-hall, cafes with neon signs, the penetrating odours of potato chips and hot dogs.I sat on the government pier and looked out across thewater. At night the lake at least was the same as it had always been, darkly shining and bearing within its black glass the streak of amber that was the path of the moon. There was no wind that evening, and everything was quiet all around me. It seemed too quiet, and then I realized that the loons were no longer here. I listened for some time, to make sure, but never once did I hear that long-drawn call, half mocking and half plaintive, spearing through the stillness across the lake.I did not know what had happened to the birds. Perhaps they had gone away to some far place of belonging. Perhaps they had been unable to find such a place, and had simply died out, having ceased to care any longer whether they lived or not. I remembered how Piquette had scorned to come along, when my father and I sat there and listened to the lake birds. It seemed to me now that in some unconscious and totally unrecognized way, Piquette might have been the only one, after all, who had heard the crying of the loons.NOTES1) Margaret Laurence: Born in Neepawa, Manitoba in Canadain publications include This Side of Jordan (1960), The Stone Angle(1964), A Jest of God (1966), The First Dwellers (1969), and The Diviners (1974).2) Rid: Louis Rid (1844-85) led two rebellions of Indians and Metis (people of mixed French and Indian blood) in 1869-70 and latter rebellion was crushed in the battle of Batoehe, Manitoba, and Riel was executed.3) patois: dialect4) broken English: English that is imperfectly spoken with mistakes in grammar and syntax5) neither flesh, fowl, nor good salt herring; also'neither fish, flesh, nor fowl' meaning 'not anything definite or recognizable'6) C.

Lesson 3 Ships in the DesertShips in the DesertAL Gore1.I was standing in the sun on the hot steel deck of a fishing ship capable of processing a fifty-ton catch on a good day. But it wasn' t a good day. We were anchored in what used to be the most productive fishing site in all of central Asia, but as I looked out over the bow , the prospects of a good catch looked bleak. Where there should have been gentle blue-green waves lapping against the side of the ship, therewas nothing but hot dry sand –as far as I could see in all directions. The other ships of the fleet were also at rest in the sand, scattered in the dunes that stretched all the way to the horizon . Ten year s ago the Aral was the fourth-largest inland sea in the world, comparable to the largest of North America's Great Lakes. Now it is disappearing because the water that used to feed it has been diverted in an ill-considered irrigation scheme to grow cotton In the user t. The new shoreline was almost forty kilometers across the sand from where the fishing fleet was now permanently docked. Meanwhile, in the nearby town of Muynak the people were still canning fish –brought not from the Aral Sea but shipped by rail through Siberia from the Pacific Ocean, more than a thousand miles away.2.My search for the underlying causes of the environmental crisis has led me to travel around the world to examine and study many of these images of destruction. At the very bottom of the earth, high in the Trans-Antarctic Mountains, with the sun glaring at midnight through a hole in the sky, I stood in the unbelievable coldness and talked with a scientist in the late tall of 1988 about the tunnel he was digging through time. Slipping his parka back to reveal a badly burned face that was cracked and peeling, he pointed to the annual layers of ice in a core sample dug from the glacier on which we were standing. He moved his finger back in time to the ice of two decadesago. "Here's where the U. S Congress passed the Clean Air Act, ”he said. At the bottom of the world, two continents away from Washington, D. C., even a small reduction in one country's emissions had changed the amount of pollution found in the remotest end least accessible place on earth.3. But the most significant change thus far in the earth' s atmosphere is the one that began with the industrial r evolution early in the last century and has picked up speed ever since. Industry meant coal, and later oil, and we began to burn lots of it –bringing rising levels of carbon dioxide (CO2) , with its ability to trap more heat in the atmosphere and slowly warm the earth. Fewer than a hundred yards from the South Pole, upwind from the ice runway where the ski plane lands and keeps its engines running to prevent the metal parts from freeze-locking together, scientists monitor the air sever al times ever y day to chart the course of that inexorable change. During my visit, I watched one scientist draw the results of that day's measurements, pushing the end of a steep line still higher on the graph. He told me how easy it is – there at the end of the earth –to see that this enormous change in the global atmosphere is still picking up speed.4. Two and a half years later I slept under the midnight sun at the other end ofour planet, in a small tent pitched on a twelve-toot-thick slab of ice floating in the frigid Arctic Ocean. After a hearty breakfast, my companions and I traveled by snowmobiles a few miles farther north to a rendezvous point where the ice was thinner –only three and a half feet thick –and a nuclear submarine hovered in the water below. After it crashed through the ice, took on its new passengers, and resubmerged, I talked with scientists who were trying to measure more accurately the thickness of the polar ice cap, which many believe is thinning as a re-suit of global warming. I had just negotiated an agreement between ice scientists and the U. S. Navy to secure the re-lease of previously top secret data from submarine sonar tracks, data that could help them learn what is happening to the north polar cap. Now, I wanted to see the pole it-self, and some eight hours after we met the submarine, we were crashing through that ice, surfacing, and then I was standing in an eerily beautiful snowcape, windswept and sparkling white, with the horizon defined by little hummocks, or "pressure ridges " of ice that are pushed up like tiny mountain ranges when separate sheets collide. But here too, CD, levels are rising just as rapidly, and ultimately temperature will rise with them –indeed, global warming is expected to push temperatures up much more rapidly in the polar regions than in the rest of the world. As the polar air warms, the ice her e will thin; and since the polar cap plays such a crucial role in the world's weather system, the consequences of a thinning cap could be disastrous.5.Considering such scenarios is not a purely speculative exercise. Six months after I returned from the North Pole, a team of scientists reported dramatic changesin the pattern of ice distribution in the Arctic, and a second team reported a still controversialclaim (which a variety of data now suggest) that, over all, the north polar cap has thinned by 2 per cent in just the last decade. Moreover, scientists established several years ago that in many land areas north of the Arctic Circle, the spring snowmelt now comes earlier every year, and deep in the tundra below, the temperature e of the earth is steadily rising.6.As it happens, some of the most disturbing images of environmental destruction can be found exactly halfway between the North and South poles –precisely at the equator in Brazil – where billowing clouds of smoke regularly black-en the sky above the immense but now threatened Amazon rain forest. Acre by acre, the rain forest is being burned to create fast pasture for fast-food beef; as Ilearned when I went there in early 1989, the fires are set earlier and earlier in the dry season now, with more than one Tennessee'sworth of rain forest being slashed and burned each year. According to our guide, the biologist Tom Lovejoy, there are more different species of birds in each square mile of the Amazon than exist in all of North America –which means we are silencing thousands of songs we have never even heard.7.But one doesn't have to travel around the world to wit-ness humankind's assault on the earth. Images that signal the distress of our global environment are now commonly seen almost anywhere. On some nights, in high northern latitudes, the sky itself offers another ghostly image that signals the loss of ecological balance now in progress. If the sky is clear after sunset -- and it you are watching from a place wherepollution hasn't blotted out the night sky altogether -- you can sometimes see a strange kind of cloud high in the sky. This "noctilucent cloud" occasionally appears when theearth is first cloaked in the evening dark-ness; shimmering above us with a translucent whiteness, these clouds seem quite unnatural. And they should: noctilucent cloudshave begun to appear more often becauseof a huge buildup of methane gas in the atmosphere. (Also called natural gas, methane is released from landfills , from coalmines and rice paddies, from billions of termites that swarm through the freshly cut forestland, from the burning of biomass and from a variety of other human activities. ) Even though noctilucent clouds were sometimes seen in the past., all this extramethane carries more water vapor into the upper atmosphere, where it condenses at much higher altitudes to form more clouds that the sun's rays still strike long aftersunset has brought the beginning of night to the surface far beneath them.8. What should we feel toward these ghosts in the sky? Simple wonder or themix of emotions we feel at the zoo? Perhaps we should feel awe for our own power:just as men "ear tusks from elephants ’ heads in such quantity as to threaten the beast with extinction, we are ripping matter from its place in the earth in such volume as toupset the balance between daylight and darkness. In the process, we are once again adding to the threat of global warming, be-cause methane has been one of thefastest-growing green-house gases, and is third only to carbon dioxide and watervapor in total volume, changing the chemistry of the upper atmosphere. But, withouteven considering that threat, shouldn't it startle us that we have now put these cloudsin the evening sky which glisten with a spectral light? Or have our eyes adjusted so completely to the bright lights of civilization that we can't see these clouds for whatthey are –a physical manifestation of the violent collision between human civilizationand the earth?9. Even though it is sometimes hard to see their meaning, we have by now all witnessed surprising experiences that signal the damage from our assault on the environment --whether it's the new frequency of days when the temperature exceeds100 degrees, the new speed with which the -un burns our skin, or the new constancy of public debate over what to do with growing mountains of waste. Butour response to these signals is puzzling. Why haven't we launched a massive effortto save our environment? To come at the question another way' Why do some images startle us into immediate action and focus our attention or ways to respond effectively? And why do other images, though sometimes equally dramatic, produce instead a Kin. of paralysis, focusing our attention not on ways to respond but ratheron some convenient, less painful distraction?10.Still, there are so many distressing images of environ-mental destruction that sometimes it seems impossible to know how to absorb or comprehend them. Before considering the threats themselves, it may be helpful to classify them and thus begin to organize our thoughts and feelings so that we may be able to respond appropriately.11.A useful system comes from the military, which frequently places a conflictin one of three different categories, according to the theater in which it takes place.There are "local" skirmishes, "regional" battles, and "strategic" conflicts. This third category is reserved for struggles that can threaten a nation's survival and must beunder stood in a global context.12.Environmental threats can be considered in the same way. For example, most instances of water pollution, air pollution, and illegal waste dumping are essentially local in nature. Problems like acid rain, the contamination of under-ground aquifers, and large oil spills are fundamentally regional. In both of these categories, there may be so many similar instances of particular local and regional problems occurringsimultaneously all over the world that the patter n appears to be global, but the problems themselves are still not truly strategic because the operation of- the global environment is not affected and the survival of civilization is not at stake.13.However, a new class of environmental problems does affect the global ecological system, and these threats are fundamentally strategic. The 600 percent increase in the amount of chlorine in the atmosphere during the last forty years has taken place not just in those countries producing the chlorofluorocarbons responsible but in the air above every country, above Antarctica, above the North Pole and the Pacific Ocean –all the way from the surface of the earth to the top of the sky. The increased levels of chlorine disrupt the global process by which the earth regulatesthe amount of ultraviolet radiation from the sun that is allowed through the atmosphere to the surface; and it we let chlorine levels continue to increase, the radiation levels will al-so increase–to the point that all animal and plant life will face a new threat to their survival.14.Global warming is also a strategic threat. The concentration of carbon dioxide and other heat-absorbing molecules has increased by almost 25 per cent since World War II, posing a worldwide threat to the earth's ability to regulate the amount of heat from the sun retained in the atmosphere. This increase in heat seriously threatens the global climate equilibrium that determines the pattern of winds, rainfall, surface temperatures, ocean currents, and sea level. These in turn determine the distribution of vegetative and animal life on land and sea and have a great effect on the location and pattern of human societies.15.In other words, the entire relationship between humankind and the earth has been transformed because our civilization is suddenly capable of affecting the entire global environment, not just a particular area. All of us know that human civilization has usually had a large impact on the environment; to mention just one example, there is evidence that even in prehistoric times, vast areas were sometimes intentionallyburned by people in their search for food. And in our own time we have reshaped a large part of the earth's surface with concrete in our cities and carefully tended rice paddies, pastures, wheat fields, and other croplands in the countryside. But these changes, while sometimes appearing to be pervasive , have, until recently, been relatively trivial factors in the global ecological sys-tem. Indeed, until our lifetime, it was always safe to assume that nothing we did or could do would have any lasting effect on the global environment. But it is precisely that assumption which must now be discarded so that we can think strategically about our new relationship to the environment.16.Human civilization is now the dominant cause of change in the global environment. Yet we resist this truth and find it hard to imagine that our effect on theearth must now be measured by the same yardstick used to calculate the strength of the moon's pull on the oceans or the force of the wind against the mountains. And it we are now capable of changing something so basic as the relationship between the earth and the sun, surely we must acknowledge a new responsibility to use that power wisely and with appropriate restraint. So far, however, We seem oblivious of the fragility of the earth's natural systems.17.This century has witnessed dramatic changes in two key factors that define the physical reality of our relation-ship to the earth: a sudden and startling surge in human population, with the addition of one China's worth of people every ten years, and a sudden acceleration of the scientific and technological revolution, which has allowed an almost unimaginable magnification of our power to affect the worldaround us by burning, cutting, digging, moving, and trans-forming the physicalmatter that makes up the earth.18.The surge in population is both a cause of the changed relationship and one of the clearest illustrations of how startling the change has been, especially when viewed in a historical context. From the emergence of modern humans 200 000 yearsago until Julius Caesar's time, fewer than 250 million people walked on the face of the earth. When Christopher Columbus set sail for the New World 1500 years later, there were approximately 500 million people on earth. By the time Thomas Jefferson wrote the Declaration of Independence in 1776, the number had doubled again, to 1 billion. By midway through this century, at the end of World War II, the number had risen to just above 2 billion people.19.In other words, from the beginning of humanity's appearance on earth to 1945, it took more than ten thousand generations to reach a world population of 2 billion people. Now, in the course of one human lifetime -- mine -- the world population will increase from 2 to more than 9 million, and it is already more than halfway there.20.Like the population explosion, the scientific and technological revolution began to pick up speed slowly during the eighteenth century. And this ongoing revolution has also suddenly accelerated exponentially. For example, it is now an axiom in many fields of science that more new and important discoveries have taken place in the last ten years that. in the entire previous history of science. While no single discover y has had the kind of effect on our relationship to the earth that unclear weapons have had on our relationship to warfare, it is nevertheless true that taken together, they have completely transformed our cumulative ability to exploit the earth for sustenance -- making the consequences, of unrestrained exploitation every bit as unthinkable as the consequences of unrestrained nuclear war.21.Now that our relationship to the earth has changed so utterly, we have to see that change and understand its implications. Our challenge is to recognize that the startling images of environmental destruction now occurring all over the world have much more in common than their ability to shock and awaken us. They are symptoms of an underlying problem broader in scope and more serious than any we have ever faced. Global warming, ozone depletion, the loss of living species, deforestation -- they all have a common cause: the new relationship between human civilization andthe earth's natural balance.22.There are actually two aspects to this challenge. The first is to realize that our power to harm the earth can in-deed have global and even permanent effects. The second is to realize that the only way to understand our new role as a co-architect of nature is to see ourselves as part of a complex system that does not operate according to the same simple rules of cause and effect we are used to. The problem is not our effect on the environment so much as our relationship with the environment. As a result, any solution to the problem will require a careful assessment of that relationship as well as the complex interrelationship among factors within civilization and between them and the major natural components of the earth's ecological system.23. The strategic nature of the threat now posed by human civilization to the global environment and the strategic nature of the threat to human civilization now posed by changes in the global environment present us with a similar set of challenges and false hopes. Some argue that a new ultimate technology, whether nuclear power or genetic engineering, will solve the problem. Others hold that only a drastic reduction of our reliance on technology can improve the conditions of life -- a simplistic notion at best. But the real solution will be found in reinventing and finally healing the relationship between civilization and the earth. This can only be accomplished by undertaking a careful reassessment of all the factors that led to the relatively recent dramatic change in the relationship. The transformation of the way we relate to the earth will of course involve new technologies, but the key changes will involve new ways of thinking about the relationship itself.。

Lesson 3 Ships in the DesertShips in the DesertAL Gore1. I was standing in the sun on the hot steel deck of a fishing ship capableof processing a fifty-ton catch on a good day. But it wasn' t a good day. We were anchored in what used to be the most productive fishing site in all of central Asia, but as I looked out over the bow , the prospects of a good catch looked bleak. Where there should have been gentle blue-green waves lapping against the side of the ship, there was nothing but hot dry sand – as far as I could see in all directions. The other ships of the fleet were also at rest in the sand, scattered in the dunes that stretched all the way to the horizon . Ten year s ago the Aral was the fourth-largest inland sea in the world, comparable to the largest of North America's Great Lakes. Now it is disappearing because the water that used to feed it has been diverted in an ill-considered irrigation scheme to grow cotton In the user t. The new shoreline was almost forty kilometers across the sand from where the fishing fleet was now permanently docked. Meanwhile, in the nearby town of Muynak the people were still canning fish – brought not from the Aral Sea but shipped by rail through Siberia from the Pacific Ocean, more than a thousand miles away.2. My search for the underlying causes of the environmental crisis has led me to travel around the world to examine and study many of these images of destruction. At the very bottom of the earth, high in the Trans-Antarctic Mountains, with the sun glaring at midnight through a hole in the sky, I stood in the unbelievable coldness and talked with a scientist in the late tall of 1988 about the tunnel he was digging through time. Slipping his parka back to reveal a badly burned face that was cracked and peeling, he pointed to the annual layers of ice in a core sample dug from the glacier on which we were standing. He moved his finger back in time to the ice of two decades ago. "Here's where the U. S Congress passed the Clean Air Act, ” he said. At the bottom of the world, two continents away from Washington, D. C., even a small reduction in one country's emissions had changed the amount of pollution found in the remotest end least accessible place on earth.3. But the most significant change thus far in the earth' s atmosphere is the one that began with the industrial r evolution early in the last century and has picked up speed ever since. Industry meant coal, and later oil, and we began to burn lots of it –bringing rising levels of carbon dioxide (CO2) , with its ability to trap more heat in the atmosphere and slowly warm the earth. Fewer than a hundred yards from the South Pole, upwind from the ice runway where the ski plane lands and keeps its engines running to prevent the metal parts from freeze-locking together, scientists monitor the air sever al times ever y day to chart the course of that inexorable change. During my visit, I watched one scientist draw the results of that day's measurements, pushing the end of a steep line still higher on the graph. He told me how easy it is –there at the end of the earth –to see that this enormous change in the global atmosphere is still picking up speed.4. Two and a half years later I slept under the midnight sun at the other end ofour planet, in a small tent pitched on a twelve-toot-thick slab of ice floating in the frigid Arctic Ocean. After a hearty breakfast, my companions and I traveled by snowmobiles a few miles farther north to a rendezvous point where the ice was thinner – only three and a half feet thick –and a nuclear submarine hovered in the water below. After it crashed through the ice, took on its new passengers, and resubmerged, I talked with scientists who were trying to measure more accurately the thickness of the polar ice cap, which many believe is thinning as a re-suit of global warming. I had just negotiated an agreement between ice scientists and the U. S. Navy to secure the re-lease of previously top secret data from submarine sonar tracks, data that could help them learn what is happening to the north polar cap. Now, I wanted to see the pole it-self, and some eight hours after we met the submarine, we were crashing through that ice, surfacing, and then I was standing in an eerily beautiful snowcape, windswept and sparkling white, with the horizon defined by little hummocks, or "pressure ridges " of ice that are pushed up like tiny mountain ranges when separate sheets collide. But here too, CD, levels are rising just as rapidly, and ultimately temperature will rise with them –indeed, global warming is expected to push temperatures up much more rapidly in the polar regions than in the rest of the world. As the polar air warms, the ice her e will thin; and since the polar cap plays such a crucial role in the world's weather system, the consequences of a thinning cap could be disastrous.5. Considering such scenarios is not a purely speculative exercise. Six months after I returned from the North Pole, a team of scientists reported dramatic changes in the pattern of ice distribution in the Arctic, and a second team reported a still controversialclaim (which a variety of data now suggest) that, over all, the north polar cap has thinned by 2 per cent in just the last decade. Moreover, scientists established several years ago that in many land areas north of the Arctic Circle, the spring snowmelt now comes earlier every year, and deep in the tundra below, the temperature e of the earth is steadily rising.6. As it happens, some of the most disturbing images of environmental destruction can be found exactly halfway between the North and South poles –precisely at the equator in Brazil –where billowing clouds of smoke regularly black-en the sky above the immense but now threatened Amazon rain forest. Acre by acre, the rain forest is being burned to create fast pasture for fast-food beef; as I learned when I went there in early 1989, the fires are set earlier and earlier in the dry season now, with more than one Tennessee's worth of rain forest being slashed and burned each year. According to our guide, the biologist Tom Lovejoy, there are more different species of birds in each square mile of the Amazon than exist in all of North America –which means we are silencing thousands of songs we have never even heard.7. But one doesn't have to travel around the world to wit-ness humankind's assault on the earth. Images that signal the distress of our global environment are now commonly seen almost anywhere. On some nights, in high northern latitudes, the sky itself offers another ghostly image that signals the loss of ecological balance now in progress. If the sky is clear after sunset -- and it you are watching from a place wherepollution hasn't blotted out the night sky altogether -- you can sometimes see a strange kind of cloud high in the sky. This "noctilucent cloud" occasionally appears when the earth is first cloaked in the evening dark-ness; shimmering above us with a translucent whiteness, these clouds seem quite unnatural. And they should: noctilucent clouds have begun to appear more often because of a huge buildup of methane gas in the atmosphere. (Also called natural gas, methane is released from landfills , from coal mines and rice paddies, from billions of termites that swarm through the freshly cut forestland, from the burning of biomass and from a variety of other human activities. ) Even though noctilucent clouds were sometimes seen in the past., all this extra methane carries more water vapor into the upper atmosphere, where it condenses at much higher altitudes to form more clouds that the sun's rays still strike long after sunset has brought the beginning of night to the surface far beneath them.8. What should we feel toward these ghosts in the sky? Simple wonder or the mix of emotions we feel at the zoo? Perhaps we should feel awe for our own power: just as men "ear tusks from elephants’ heads in such quantity as to threaten the beast with extinction, we are ripping matter from its place in the earth in such volume as to upset the balance between daylight and darkness. In the process, we are once again adding to the threat of global warming, be-cause methane has been one of the fastest-growing green-house gases, and is third only to carbon dioxide and water vapor in total volume, changing the chemistry of the upper atmosphere. But, without even considering that threat, shouldn't it startle us that we have now put these clouds in the evening sky which glisten with a spectral light? Or have our eyes adjusted so completely to the bright lights of civilization that we can't see these clouds for what they are – a physical manifestation of the violent collision between human civilization and the earth?9. Even though it is sometimes hard to see their meaning, we have by now all witnessed surprising experiences that signal the damage from our assault on the environment --whether it's the new frequency of days when the temperature exceeds 100 degrees, the new speed with which the -un burns our skin, or the new constancy of public debate over what to do with growing mountains of waste. But our response to these signals is puzzling. Why haven't we launched a massive effort to save our environment? To come at the question another way' Why do some images startle us into immediate action and focus our attention or ways to respond effectively? And why do other images, though sometimes equally dramatic, produce instead a Kin. of paralysis, focusing our attention not on ways to respond but rather on some convenient, less painful distraction?10. Still, there are so many distressing images of environ-mental destruction that sometimes it seems impossible to know how to absorb or comprehend them. Before considering the threats themselves, it may be helpful to classify them and thus begin to organize our thoughts and feelings so that we may be able to respond appropriately.11. A useful system comes from the military, which frequently places a conflict in one of three different categories, according to the theater in which it takes place. There are "local" skirmishes, "regional" battles, and "strategic" conflicts. This third category is reserved for struggles that can threaten a nation's survival and must beunder stood in a global context.12. Environmental threats can be considered in the same way. For example, most instances of water pollution, air pollution, and illegal waste dumping are essentially local in nature. Problems like acid rain, the contamination of under-ground aquifers, and large oil spills are fundamentally regional. In both of these categories, there may be so many similar instances of particular local and regional problems occurring simultaneously all over the world that the patter n appears to be global, but the problems themselves are still not truly strategic because the operation of- the global environment is not affected and the survival of civilization is not at stake.13. However, a new class of environmental problems does affect the global ecological system, and these threats are fundamentally strategic. The 600 percent increase in the amount of chlorine in the atmosphere during the last forty years has taken place not just in those countries producing the chlorofluorocarbons responsible but in the air above every country, above Antarctica, above the North Pole and the Pacific Ocean – all the way from the surface of the earth to the top of the sky. The increased levels of chlorine disrupt the global process by which the earth regulates the amount of ultraviolet radiation from the sun that is allowed through the atmosphere to the surface; and it we let chlorine levels continue to increase, the radiation levels will al-so increase – to the point that all animal and plant life will face a new threat to their survival.14. Global warming is also a strategic threat. The concentration of carbon dioxide and other heat-absorbing molecules has increased by almost 25 per cent since World War II, posing a worldwide threat to the earth's ability to regulate the amount of heat from the sun retained in the atmosphere. This increase in heat seriously threatens the global climate equilibrium that determines the pattern of winds, rainfall, surface temperatures, ocean currents, and sea level. These in turn determine the distribution of vegetative and animal life on land and sea and have a great effect on the location and pattern of human societies.15. In other words, the entire relationship between humankind and the earth has been transformed because our civilization is suddenly capable of affecting the entire global environment, not just a particular area. All of us know that human civilization has usually had a large impact on the environment; to mention just one example, there is evidence that even in prehistoric times, vast areas were sometimes intentionally burned by people in their search for food. And in our own time we have reshaped a large part of the earth's surface with concrete in our cities and carefully tended rice paddies, pastures, wheat fields, and other croplands in the countryside. But these changes, while sometimes appearing to be pervasive , have, until recently, been relatively trivial factors in the global ecological sys-tem. Indeed, until our lifetime, it was always safe to assume that nothing we did or could do would have any lasting effect on the global environment. But it is precisely that assumption which must now be discarded so that we can think strategically about our new relationship to the environment.16. Human civilization is now the dominant cause of change in the global environment. Yet we resist this truth and find it hard to imagine that our effect on theearth must now be measured by the same yardstick used to calculate the strength of the moon's pull on the oceans or the force of the wind against the mountains. And it we are now capable of changing something so basic as the relationship between the earth and the sun, surely we must acknowledge a new responsibility to use that power wisely and with appropriate restraint. So far, however, We seem oblivious of the fragility of the earth's natural systems.17. This century has witnessed dramatic changes in two key factors that define the physical reality of our relation-ship to the earth: a sudden and startling surge in human population, with the addition of one China's worth of people every ten years, and a sudden acceleration of the scientific and technological revolution, which has allowed an almost unimaginable magnification of our power to affect the world around us by burning, cutting, digging, moving, and trans-forming the physical matter that makes up the earth.18. The surge in population is both a cause of the changed relationship and one of the clearest illustrations of how startling the change has been, especially when viewed in a historical context. From the emergence of modern humans 200 000 years ago until Julius Caesar's time, fewer than 250 million people walked on the face of the earth. When Christopher Columbus set sail for the New World 1500 years later, there were approximately 500 million people on earth. By the time Thomas Jefferson wrote the Declaration of Independence in 1776, the number had doubled again, to 1 billion. By midway through this century, at the end of World War II, the number had risen to just above 2 billion people.19. In other words, from the beginning of humanity's appearance on earth to 1945, it took more than ten thousand generations to reach a world population of 2 billion people. Now, in the course of one human lifetime -- mine -- the world population will increase from 2 to more than 9 million, and it is already more than halfway there.20. Like the population explosion, the scientific and technological revolution began to pick up speed slowly during the eighteenth century. And this ongoing revolution has also suddenly accelerated exponentially. For example, it is now an axiom in many fields of science that more new and important discoveries have taken place in the last ten years that. in the entire previous history of science. While no single discover y has had the kind of effect on our relationship to the earth that unclear weapons have had on our relationship to warfare, it is nevertheless true that taken together, they have completely transformed our cumulative ability to exploit the earth for sustenance -- making the consequences, of unrestrained exploitation every bit as unthinkable as the consequences of unrestrained nuclear war.21. Now that our relationship to the earth has changed so utterly, we have to see that change and understand its implications. Our challenge is to recognize that the startling images of environmental destruction now occurring all over the world have much more in common than their ability to shock and awaken us. They are symptoms of an underlying problem broader in scope and more serious than any we have ever faced. Global warming, ozone depletion, the loss of living species, deforestation -- they all have a common cause: the new relationship between human civilization andthe earth's natural balance.22. There are actually two aspects to this challenge. The first is to realize that our power to harm the earth can in-deed have global and even permanent effects. The second is to realize that the only way to understand our new role as a co-architect of nature is to see ourselves as part of a complex system that does not operate according to the same simple rules of cause and effect we are used to.

As a result, any solution to the problem will require a careful assessment of that relationship as well as the complex interrelationship among factors within civilization and between them and the major natural components of the earth's ecological system.23.

As a result, any solution to the problem will require a careful assessment of that relationship as well as the complex interrelationship among factors within civilization and between them and the major natural components of the earth's ecological system.23. The strategic nature of the threat now posed by human civilization to the global environment and the strategic nature of the threat to human civilization now posed by changes in the global environment present us with a similar set of challenges and false hopes. Some argue that a new ultimate technology, whether nuclear power or genetic engineering, will solve the problem. Others hold that only a drastic reduction of our reliance on technology can improve the conditions of life -- a simplistic notion at best. But the real solution will be found in reinventing and finally healing the relationship between civilization and the earth. This can only be accomplished by undertaking a careful reassessment of all the factors that led to the relatively recent dramatic change in the relationship. The transformation of the way we relate to the earth will of course involve new technologies, but the key changes will involve new ways of thinking about the relationship itself.。
