NATURE ON DISPLAY IN AMERICAN ZOOS by Elizabeth Hanson The first zoo in the United States opened in Philadelphia in 1874, followed by the Cincinnati Z
2、oo the next year. By 1940 there were zoos in more than one hundred American cities. The Philadelphia Zoo was more thoroughly planned and better financed than most of the hundreds of zoos that would open later but in its landscape and its mission - to both educate and entertain - it embodied ideas ab
3、out how to build a zoo that stayed consistent for decades. The zoos came into existence in the late nineteenth century during the transition of the United States from a rural and agricultural nation to an industrial one. The population more than doubled between 1860 and 1900. As more middle-class pe
4、ople lived in cities, they began seeking new relationships with the natural world as a place for recreation, self-improvement, and spiritual renewal. Cities established systems of public parks, and nature tourism - already popular - became even more fashionable with the establishment of national par
5、ks. Nature was thought to be good for people of all ages and classes. Nature study was incorporated into school curricula, and natural history collecting became an increasingly popular pastime. At the same time, the fields of study which were previously thought of as natural history grew into separa
6、te areas such as taxonomy, experimental embryology and genetics, each with its own experts and structures. As laboratory research gained prestige in the zoology departments of American universities, the gap between professional and amateur scientific activities widened. Previously, natural history h
7、ad been open to amateurs and was easily popularized, but research required access to microscopes and other equipment in laboratories, as well as advanced education. The new zoos set themselves apart from traveling animal shows by stating their mission as education and the advancement of science, in
8、addition to recreation. Zoos presented zoology for the non-specialist, at a time when the intellectual distance between amateur naturalists and laboratory-oriented zoologists was increasing. They attracted wide audiences and quickly became a feature of every growing and forward-thinking city. They w
9、ere emblems of civic pride on a level of importance with art museums, natural history museums and botanical gardens. Most American zoos were founded and operated as part of the public parks administration. They were dependent on municipal funds, and they charged no admission fee. They tended to asse
10、mble as many different mammal and bird species as possible, along with a few reptiles, exhibiting one or two specimens of each, and they competed with each other to become the first to display a rarity, like a rhinoceros. In the constant effort to attract the public to make return visits, certain ty
11、pes of display came in and out of fashion; for example, dozens of zoos built special islands for their large populations of monkeys. In the 1930s, the Works Progress Administration funded millions of dollars of construction at dozens of zoos. For the most part, the collections of animals were organi
12、sed by species in a combination of enclosures according to a fairly loose classification scheme. Although many histories of individual zoos describe the 1940s through the 1960s as a period of stagnation, and in some cases there was neglect, new zoos continued to be set up all over the country. In th
13、e 1940s and 1950s, the first zoos designed specifically for children were built, some with the appeal of farm animals. An increasing number of zoos tried new ways of organizing their displays. In addition to the traditional approach of exhibiting like kinds together, zoo planners had a new approach
14、of putting animals in groups according to their continent of origin and designing exhibits showing animals of particular habitats, for example, polar, desert, or forest. During the 1960s, a few zoos arranged some displays according to animal behavior; the Bronx Zoo, for instance, opened its World of
15、 Darkness exhibit of nocturnal animals. Paradoxically, at the same time as zoo displays began incorporating ideas about the ecological relationships between animals, big cats and primates continued to be displayed in bathroom-like cages lined with tiles. By the 1970s, a new wave of reform was stirri
16、ng. Popular movements for environmentalism and animal welfare called attention to endangered species and to zoos that did not provide adequate care for their animals. More projects were undertaken by research scientists and zoos began hiring full-time vets as they stepped up captive breeding program
17、s. Many zoos that had been supported entirely by municipal budgets began recruiting private financial support and charging admission fees. In the prosperous 1980s and 1990s, zoos built realisticlandscape immersionexhibits, many of them around the theme of the tropical rainforest and, increasingly, c
18、onservation moved to the forefront of zoo agendas. Although zoos were popular and proliferating institutions in the United States at the turn of the twentieth century, historians have paid little attention to them. Perhaps zoos have been ignored because they were, and remain still, multi-purpose ins
19、titutions, and as such they fall between the categories of analysis that historians often use. In addition, their stated goals of recreation, education, the advancement of science, and protection of endangered species have often conflicted. Zoos occupy a difficult middle ground between science and s
20、howmanship, high culture and low, remote forests and the cement cityscape, and wild animals and urban people.

26、ould spend about 20 minutes on Questions 14-26, which are based on Reading Passage 2 below. Can we prevent the poles from melting? A growing number of scientists are looking to increasingly ambitious technological fixes to halt the tide of global warming. Mark Rowe reports. A Such is our dependence
27、on fossil fuels, and such is the volume of carbon dioxide we have already released into the atmosphere, that most climate scientists agree that significant global warming is now inevitable - the best we can hope to do is keep it at a reasonable level, and even that is going to be an uphill task. At
28、present, the only serious option on the table for doing this is cutting back on our carbon emissions, but while a few countries are making major strides in this regard, the majority are having great difficulty even stemming the rate of increase, let alone reversing it. Consequently, an increasing nu
29、mber of scientists are beginning to explore the alternatives. They all fall under the banner of geoengineering - generally defined as the intentional large-scale manipulation of the environment. B Geoengineering has been shown to work, at least on a small, localised scale, for decades. May Day parad
30、es in Moscow have taken place under clear blue skies, aircraft having deposited dry ice, silver iodide and cement powder to disperse clouds. Many of the schemes now suggested look to do the opposite, and reduce the amount of sunlight reaching the planet. One scheme focuses on achieving a general coo
31、ling of the Earth and involves the concept of releasing aerosol sprays into the stratosphere above the Arctic to create clouds of sulphur dioxide, which would, in turn, lead to a global dimming. The idea is modelled on historical volcanic explosions, such as that of Mount Pinatubo in the Philippines
32、 in 1991, which led to a short-term cooling of global temperatures by 0.5C. The aerosols could be delivered by artillery, highflying aircraft or balloons. C Instead of concentrating on global cooling, other schemes look specifically at reversing the melting at the poles. One idea is to bolster an ic
33、e cap by spraying it with water. Using pumps to carry water from below the sea ice, the spray would come out as snow or ice particles, producing thicker sea ice with a higher albedo(the ratio of sunlight reflected from a surface)to reflect summer radiation. Scientists have also scrutinised whether i
34、t is possible to block icefjords in Greenland with cables which have been reinforced, preventing icebergs from moving into the sea. Veli Albert Kallio, a Finnish scientist, says that such an idea is impractical, because the force of the ice would ultimately snap the cables and rapidly release a larg
35、e quantity of frozen ice into the sea. However, Kallio believes that the sort of cables used in suspension bridges could potentially be used to divert, rather than halt, the southward movement of ice from Spitsbergen. It would stop the ice moving south, and local currents would see them float northw
36、ards, he says. D A number of geoengineering ideas are currently being examined in the Russian Arctic. These include planting millions of birch trees: the thinking, according to Kallio, is that their white bark would increase the amount of reflected sunlight. The loss of their leaves in winter would
37、also enable the snow to reflect radiation. In contrast, the native evergreen pines tend to shade the snow and absorb radiation. Using ice-breaking vessels to deliberately break up and scatter coastal sea ice in both Arctic and Antarctic waters in their respective autumns, and diverting Russian river
38、s to increase cold-water flow to ice-forming areas, could also be used to slow down warming, Kallio says. You would need the wind to blow the right way, but in the right conditions, by letting ice float free and head north, you would enhance ice growth. E But will such ideas ever be implemented? The
39、 major counter-arguments to geoengineering schemes are, first, that they are a cop-out that allow us to continue living the way we do, rather than reducing carbon emissions; and, second, even if they do work, would the side-effects outweigh the advantages? Then theres the daunting prospect of upkeep
40、 and repair of any scheme as well as the consequences of a technical failure. I think all of us agree that if we were to end geoengineering on a given day, then the planet would return to its pre-engineered condition very rapidly, and probably within 10 to 20 years, says Dr Phil Rasch, chief scienti
41、st for climate change at the US-based Pacific Northwest National Laboratory. Thats certainly something to worry about. I would consider geoengineering as a strategy to employ only while we manage the conversion to a non-fossil-fuel economy. The risk with geoengineering projects is that you can “over
42、shoot“, says Dr Dan Lunt, from the University of Bristol. You may bring global temperatures back to pre-industrial levels, but the risk is that the poles will still be warmer than they should be and the tropics will be cooler than before industrialisation. F The main reason why geoengineering is cou
43、ntenanced by the mainstream scientific community is that most researchers have little faith in the ability of politicians to agree - and then bring in - the necessary carbon cuts. Even leading conservation organisations believe the subject is worth exploring. As Dr Martin Sommerkorn, a climate chang
44、e advisor says, But human-induced climate change has brought humanity to a position where it is important not to exclude thinking thoroughly about this topic and its possibilities despite the potential drawbacks. If, over the coming years, the science tells us about an ever-increased climate sensiti
45、vity of the planet - and this isnt unrealistic - then we may be best served by not having to start our thinking from scratch. Questions 14-18 Reading Passage 2 has six paragraphs, A-F.

48、ing projects A range of geoengineering ideas has been put forward, which aim either to prevent the melting of the ice caps or to stop the general rise in global temperatures. One scheme to discourage the melting of ice and snow involves introducing【 R19】 _to the Arctic because of their colour. The b
49、uild-up of ice could be encouraged by dispersing ice along the coasts using special ships and changing the direction of some【 R20】 _but this scheme is dependent on certain weather conditions. Another way of increasing the amount of ice involves using【 R21】 _to bring water to the surface. A scheme to stop ice moving would use【 R22】 _but this method is more likely to be successful in preventing the ice from travelling in one direction rather than stopping it altogether.
