Unit 17 Saving the Environment……………………271
拯救环境
比起消除真正的污染,当前加强对于环境保护重要性的认识,其意义还要深远得多。我们太晚才认识到,当我们在生产﹑规模﹑速度和发展这些方面取得“成就”的时候,生活条件已大大恶化……
The effort to save the environment derives1 much of its political popularity(普及)from the impact of immediate2 personal inconveniences:a sewage(严重的)polluted beach, the smog that leaves one’s eyes watering, the black granules(小颗粒)of soot(煤烟)that drift in through an open window, traffic jams(交通堵塞), noise, the smoking vehicles and industries.
But the significance of the current consciousness for the environment protection goes much, much deeper than nuisance reduction. It is a postponed3 recognition that as we “succeed” in terms of production, size, speed, growth, quality of life may deteriorate4 our living conditions disastrously5. It is a delayed recognition of our unity6 with nature, a concern for man himself and his natural environment. It is a delayed awareness7 that our fate as individuals is in fellowship with our fate as a species and the future of life in this planet.
Precisely8 because we have recognized late, we must redouble(加倍)our efforts to gain command of the situation, we must take all the means at our disposal—basic and applied9 research, public education, and, above all, the governmental action.
We could have a productive, prosperous society without destroying the ecological10 balance of our environment. Why should man create the impropriety(不适当的事物)of material plenty around poisoned air, polluted water and mountains of solid wastes?
Russia is currently concerned with the fight to save Lake Baikal(贝加尔湖), four hundreds miles long and six thousand feet deep. The beautiful, wooded shoreline is being inhabited upon by new industrial plants—and a new generation of Russia conservationists(自然资源保护论者)is raising a challenge, the united states contains less than 6percent of the world’s population—but it consumes 34 percent of the world’s production and brings about much more than 5 percent of the world’s pollution. Each American in his lifetime uses an average of 26 millions gallons of water, 21 000 gallons of gasoline, 10 000 pounds of meat, 28 000 pounds of milk and cream, $ 6 000 worth of clothing and $ 7 000 worth of furniture. Each year, people in the United States discard 7 millions automobiles12 and 100 millions tires, 20 million tons of paper, 28 billion bottles and 48 billions cans. Just to collect the garbage cost $2.8 billion a year. The United States factories get rid of 165 million tons of solid wastes and 172 million tons of smoke, vehicle emissions13 and other forms of atmospheric14(大气的)pollution. Eighty-three million United States automobiles contribute 60 percent of air pollution in urban districts. Each year, the United States paves over a million acres of field, forests and rural green spaces.
Fortunately, saving the environment has become a popular crusade(圣战)—aided especially by the energy and concern of young people, man is beginning to realize that he must drastically alter his pattern of shortsighted(无远见的)abuse of the natural resources if he wants to survive.
Large firms are moving to compete with the small ones; specialist makers16 of pollution control equipments have watched their own sales increase tenfold.
We must achieve interaction of popular pressures and enthusiasm, the precise application of sizable(相当大的)funds and technological17 skills, and the wise action of government at all the levels of our socio-economic system. That means federal, state and local governments should coordinate18 their efforts to solve the problems.
While polluted air almost never appears on a death certificate, medical research strongly implicates(暗示)it as a contributing cause of many deaths. Polluted air influences health gradually, so its effects are extremely difficult to pinpoint(查明). However, mounting evidence indicates a steady increase in the incidence of such respiratory(呼吸的)diseases as asthma(哮喘), bronchitis(支气管炎),lung cancer, and emphysema(肺气肿). Cities with an abundance of air pollution have the greatest incidence of these diseases.
The number-one cause of atmospheric pollution is the automobile11. Some further observation is needed on this subject, but the automobile is indeed a crucial polluter and killer19. The accident death rate from automobile is currently in excess of fifty-five thousand people every year. The automobile creates traffic jams in the cities and junkyards(旧汽车丢弃地)in the countryside. Experts say the family car has made possible not only the spread of the suburbs but also the abandonment(废弃)of central cities. The internal combustion20 engine(内燃机)may well give place to other forms of propulsion(推进). However, research work on the electricity, steam and hybrid21 gasoline-natural gas powered(油气两用的)automobiles has not proceeded very far. The fact is that no one has yet invented a substitute which has adequate performance, reliability(可靠性),and safety, or which can be produced at a reasonable cost and requires a minimum of maintenance.
We have made progress in cleaning up the atmosphere, in part because the public recognizes the health dangers and is willing to accept the expenditures22. But there has little progress, nationally speaking, against noise pollution, because so little is known about the subject.
Noise pollution is, in face, a threat to millions that could be as dangerous as the pollution of the atmosphere. Clinicians(临床医生)believe that prolonged exposure to noise, especially to sharp, sudden, surprise sounds, produces severe involuntary response in the digestive(消化的)nervous systems.
Human ears cannot shut out noise in sleep in the same way eyelids(眼皮)shut out light. The constriction(收缩)of blood vessels23 by noise pollution can go on all night long. Many people are fatigued24 by their efforts to remain asleep in the midst of urban noise.
The lowest audible(可听到的)sound is one decibel25(分贝)—and louder sounds are measured upward on a logarithmic(对数的)scale. Twenty decibels26 is ten times 10 decibels, and 80 decibels is a million times louder than 20 decibels—and 30 or so if it is dropped on a wooden library floor. The ordinary conversation level in an average size room runs at approximately 60 decibels. Sounds of 80 decibels or more are uncomfortable to human ears. Decibel levels of 90 or more are estimated by doctors to present a health hazard. Decibel levels of 100 or more are a definite threat to hearing.
Heavy city traffic is measured at 90to 95 decibels, and a common household food blender at 93 decibels. Air hammers(气锤)and air compressors(空气压缩机)along city sidewalks(人行道)erupt in sudden blasts of 95 decibels. This is also the reading, incidentally, of a subway train screaming around a curve. Farm tractors can sound at 98 decibels, roughly the same as a newspaper printing press. Incredible as it may seem, there are many familiar implements27 of modern life that measure 100 decibels and above. These include loud outboard(舷外的)motors, powering along off-shore(离岸), 102 decibels; textile looms28, 106decibels; riveting29 guns(铆枪), 110 decibels on up, usually way up.
There are psychological effects of noise pollution. Starting sounds contribute to outbursts of anger among normally placid(平静的)people. A dropper toy, a blaring television set, a police siren, a tingling(叮当响的)telephone, a sudden truck noise, might propel a neurotic(神经病患者)to minor30 violence. As for prolonged, steady sound, men and women exposed to it are more inclined to quarrel or act foolishly.
A British study showed not long ago that people who lived near deafening(震聋)London airport were admitted to mental hospitals at a higher rate than people living in quiet districts in the same part of the country. The noises of our daily life have been blamed variously for the high divorce rate, social conflict, indigestion(消化不良),nervous breakdown(神经失常), high blood pressure, heart failure(心力衰竭), and even insanity(精神错乱). The damage is done deep in the inner ear, near the brain, to the delicate cilia(纤毛), rows of microscopic31, hair like organs capable of responding individually to thousands of frequencies of sound, the first of these tiny organs to be injured by noise are those, which respond to the higher frequencies above the level of speech. But the hearing loss takes place very gradually, and deafness is often not noticed until it is too late to take corrective measures.
In fact, most city dwellers(居民)have “invented” their own methods of withstanding noise pollution. They turn on a low decibel producer—a fan or an air conditioner—to strain out and distill32 the louder noises and make indoor life more preferable. Some states have passed laws against defective33 motorcycle mufflers(消声器), against alarms on other than emergency vehicles, against inadequate(不充足的)mufflers on automobiles.
New York City prohibits the use of automobile horns on stationary34 vehicles, except as a danger signal. The city also bans the use of any vehicles out of repair to avoid creating loud and unnecessary grating(摩擦声), clashing, or other noises. The city forbids the unnecessary blowing of steam whistles and, along with the state, the use of a stationary internal combustion engine without an effective muffler. These are city laws against excessive noise near schools and hospitals and in the loading and unloading of vehicles, the shouting of street hawkers(叫卖小贩)is forbidden, the dull hum(嗡嗡声)of fans and air conditioners continues to be the citizen’s principal weapon against neighbor’s conversations. The development of off-site, prefabricated(预制的)houses by the Office of Housing and Urban Development in Washington has offered new hope of effective noise controls. The house devised is simpler and less costly35 to install. Another promising36 new concert is the development of portable, soundproofed(隔音的)rooms for installation in homes, offices, or industrial plants.
Noise control technology in transportation is also being devised. General Motors(美国通用汽车公司)has designed quieter public trucks, conducting new research into noise abatement(消除)features of body and structural(结构的)framework design, and making its findings available to other manufacturers(生产厂商).
Trucks may be required to reduce diesel37 engine(柴油机)noise by simple techniques that have already been tested in diesel bus design, basically a sealed engine compartment38, mechanically ventilated by fans. Small discharge and line mufflers may reduce air brake noise and frantic(狂乱的)pumping sound. Tired may be designed with cross bar and rib15 treads(轮胎面)to minimize the familiar whirring(旋转的)noise.
The air transportation industry also has a major noise problem. Aircraft technology is only one part of the problem, however. The other is the quality of life in residential39, industrial, and wildlife areas in the vicinity of airports. The noise of the jets is indeed substantial. Environmental factors must be considered well in advance in all aspects of aviation planning.
Reducing the pollution of our rivers, lakes, streams, and offshore40 waters is important fir the coming generation.
We have made visible and encouraging progress by operating new sewage(污水)disposal projects. Sewage treatment plant’s construction has improved the quality of ten billion gallons of water a day—some 20 percent of all our fresh water resources. Pollution of the rivers, streams, and lakes must be ended as possible—as a prerequisite(先决条件)for our good future and our good health. We can stop water pollution if we are prepared to pay the price.
The basic technology of sewage control has been successfully developed. The primary need is for more sewage treatment of plants and filters. Municipal collection systems gather the sewage in lateral41 and trunk sewers42. When treatment is not provided, the sewage is dumped directly into the nearest waters. Filters ate designed to gather sewage from these trunk and lateral sewers and bring them to the treatment facilities.
Treatment plants receive sewage from collection systems and from filers. Treatment then eliminates many of the harmful(有害的)composition of sewage by sedimentation(沉淀), biological or chemical action(生化反应), and purification. Primary treatment (sedimentation) is always necessary. Secondary treatment (biological and chemical action) is also always necessary. Chlorination(氯化处理)(purification)is needed in most cases. To eliminate existing pollution in industries not tied to municipal sewage collection systems, there must be separate industrial facilities and even changers in industrial processes.
