1、Lesson 3,At War with the Planet,工业城市里高耸的烟囱，空气污染,河道里堆满了人们的生活垃圾，水污染,美丽的“西湖水”,取水口因黄河的水污染停止取水。华夏的母亲河？,2009年8月25日，印度博帕尔的一名小女孩蹲在雨中。雨水渗透含有碳化物的地表，进入地下水系，当地3万多名群众遭受着地下水污染的威胁。,杀戮不曾停止,2010年3月25日，云南。当地居民在“污水池”中取水。 干旱+水污染=？,2010年8月7日，甘肃舟曲特大泥石流,北京，人们堵在路上。,I. Background Information,Author,Barry Commoner (1917- ) (

2、born May 28, 1917) is an American biologist, college professor, and eco-socialist. He was also editor of Science Illustrated(科学画报)magazine.,Commoner was born in Brooklyn. He received his bachelors degree in zoology from Columbia University(1937) and his masters and doctoral degrees from Harvard Univ

3、ersity(1938, 1941). After serving in the US Navy during WWII, he moved to St. Louis where became a professor of plant physiology at Washington University. He taught there for 34 years and during this period, in 1966, he founded the Center for the Biology of Natural Systems to study “the science of t

4、he total environment”.,In the late 1950s, Commoner became well-known for his opposition to nuclear testing. He went on to write several books about the negative ecological effects of above-ground nuclear testing. His 1971 book The Closing Circle suggested a left-wing, eco-socialist response to the l

5、imits to growth thesis, postulating that capitalist technologies were chiefly responsible for environmental degradation(恶化), as opposed to population pressures.,He believed that technological, and above all social development would lead to a natural decrease in both population growth and environment

6、al damage. Commoner criticized Ronald Reagan and George Bush for regulating pollution and not preventing it.,His Workings,Science and Survival. 1966. The Closing Circle: Nature, Man, and Technology. 1971. The Poverty of Power: Energy and the Economic Crisis. 1976. The Politics of Energy. 1979. Makin

7、g Peace With the Planet. 1990.,Cultural notes,Three Mile Island (1979) 三里岛事件,The accident at the Three Mile Island Unit 2 (TMI-2) nuclear power plant near Middletown, Pennsylvania, on March 28, 1979, was the most serious in U.S. commercial nuclear power plant operating history, even though it led to

8、 no deaths or injuries to plant workers or members of the nearby community.,But it brought about sweeping changes involving emergency response planning, reactor operator training, human factors engineering, radiation protection, and many other areas of nuclear power plant operations. It also caused

9、the U.S. Nuclear Regulatory Commission to tighten and heighten its regulatory oversight(疏忽).,1979年3月28日凌晨4时，美国宾夕法尼亚州的三里岛核电站第二组反应堆的操作室里，红灯闪亮，汽笛报警，涡轮机停转，堆心压力和温度骤然升高。2小时后，大量放射性物质溢出。6天以后，堆心温度才开始下降，蒸气泡消失-引起氢爆炸的威胁免除了。100吨铀燃料虽然没有熔化，但有60的铀棒受到损坏，反应堆最终陷于瘫痪。事故发生后，全美震惊，核电站附近约20万居民撤出这一地区。在过去的30年间，三里岛事件成为不再进行新核能建

10、筑开发的理由，全部核能的开发速度也大大放缓。,The Chernobyl Disaster(1986) 乌克兰切尔诺贝利核电站事故,史上最严重的核反应事故发生地。1986年4月26日，乌克兰切尔诺贝利核反应堆爆炸，核反应炉熔毁，大量辐射能排放到大气中，导致原子尘污染。污染还扩散到了西部国家，从当时的苏联到接近欧洲，数以万计的儿童被诊断为甲状腺癌，核反应爆炸区近20英里范围至今仍被封锁。4号反应堆被人们用巨大的石棺密封起来，这是个漫长的核退散过程。,On April 25-26th, 1986, the Worlds worst nuclear power accident occurred a

11、t Chernobyl in the former USSR (now Ukraine). The Chernobyl nuclear power plant located 80 miles north of Kiev had 4 reactors(核反应堆) and while testing reactor number 4 numerous safety procedures were disregarded. At 1:23 am the chain reaction in the reactor became out of control creating explosions a

12、nd a fireball which blew off the reactors heavy steel and concrete lid.,The Chernobyl accident killed more than 30 people immediately, and as a result of the high radiation levels in the surrounding 20-mile radius(半径), 13500 people had to be evacuated(撤离，疏散).,800年：专家称消除切尔诺贝利核泄事故漏后遗症需800年； 9.3万人：20年前

13、的切尔诺贝利核电站事故造成致癌死亡人数约为9.3万人左右； 27万人：27万人因切尔诺贝利核泄漏事故患上癌症，其中致死9.3万人； 34万人：核泄漏事故发生后，前苏联立即疏散了11万多人，随后数年，又从污染严重地区搬迁了23万人，前后共疏散34万余人； ,1984年12月2日深夜，联合碳化物公司(Union Carbide)位于印度博帕尔的杀虫剂制造厂发生事故，45吨有毒化学成分从设备中泄露出来。数小时内上千人因此丧命。在接下来的数月时间里，又有1.5万人中毒身亡，近50万人不同程度受影响。受影响的人当中大多数人失明、器官坏死或是有其他身体故障。受污染区域中出生的婴儿，大多数也存在不同程度的问

14、题和生理缺陷。1989年联合碳化物公司赔偿5亿美元给受害者们，这笔赔偿金都不够受害人10年的治疗费用。博帕尔仍是全球工业泄露灾难的重症区。,What happened in Bhopal(印度博帕尔)?,On the night of Dec. 2nd and 3rd, 1984, a Union Carbide plant in Bhopal, India, began leaking 27 tons of the deadly gas. None of the six safety systems designed to contain such a leak were operation

15、al, allowing the gas to spread throughout the city of Bhopal. Half a million people were exposed to(暴露于，接触到)the gas and 20,000 have died to date as a result of their exposure.,More than 120,000 people still suffer from ailments caused by the accident and the subsequent pollution at the plant site. T

16、hese ailments include blindness, extreme difficulty in breathing, and gynecological(妇科的) disorders. The site has never been properly cleaned up and it continues to poison the residents of Bhopal.,II. About the Essay,Making Peace With the Planet is a 1990 book by Barry Commoner. Commoner argues that,

17、 despite billions of dollars spent to save the environment, America is still in a deep environmental crisis. The book argues that environmental pollution can be prevented only through fundamental redesign of the way we produce goods.,Four Laws of Ecology,1. Everything is Connected to Everything Else

18、. There is one ecosphere for all living organisms and what affects one, affects all. 2. Everything Must Go Somewhere. There is no “waste” in nature and there is no “away” to which things can be thrown.,3. Nature Knows Best. Humankind has fashioned technology to improve upon nature, but such change i

19、n a natural system is, says Commoner, “likely to be detrimental to that system.” 4. There Is No Such Thing as a Free Lunch. Exploitation of nature will inevitably involve the conversion of resources from useful to useless forms.,Outline,Part 1 (para.1):,introduction-theme,why the two worlds are at w

20、ar,1st law of the ecosphere - man-made object and surrounding,the closed cyclical process of ecosphere such image lulls us into complacency.,5. The technosphere has becomegovern the ecosphere. (Para. 5),Human activities have taken place over such large areas and with such intensity that they have al

21、ready caused disastrous effects on ecology.,6. Indeed, in the evolutionary sense, it fitted properly into the preexisting system. (Para. 6),The fish could play its role because it became a necessary link with the processes preceding it and the processes following it in the ecological system.,7. A ca

22、r, for example, imposes itselfbeing defined by it. (Para. 7),A car does not respond to its environment but insists on its own needs being met.,8. Yield rose, but not in proportion to the rate of fertilizer application(Para. 9),The farmers applied more and more chemical fertilizer, but production did

23、 not increase at the same rate.,9. their waste is flushed into the sewer systemat a treatment plant(Para. 11),People, after digestion, excrete the waste which is flushed into the sewer system. The sewage gets to a treatment plant which modifies it, but it is still waste after being processed. The wa

24、ste does not reenter the life cycle but disturbs the natural processes wherever it is dumped.,10. Left to their own devices, ecosystems are conservative(Para. 12),If the ecosystems are not upset by outside intrusion, they will remain the same with very little change.,to be free to do as one wishes,1

25、1. In contrast to the ecosphere, change and variation. (Para. 13),The characteristics of the objects and materials in the technosphere are rapid change and great variety.,12. Model T Ford (Para. 13),In the 1920s. Henry Ford adapted the assembly line and the conveyor belt to car production and turned

26、 out cars of a standardized model, the famous Model T Ford.,By 1925 he was producing a car every 10 seconds and the Model T could be bought for only $290. Henry Ford gave the American people the first mass-produced car.,Henry Ford与Model T,13. Nylon, for example, unlike, is not biodegradable-that is,

27、 there is nothat can break it down . (Para. 13),翻:例如尼龙，它不会像纤维素那样的天然聚合物一样可以进行生物分解-也就是说，在现存的有机生物中还没有发现哪种酶可以分解尼龙。,14. Regarded only as a failurethat destroy the plant. (Para. 15),If you regard the disaster at Chernobyl as a technical matter, then the disaster can be seen as the destruction of the nuclear plant by a fire.,15. In the technosphere, debts are repaid from within and, canceled. (Para. 16),In the economic field, debts are re
