Large mammals, in particular, have a hard

24、time at the hands of humanity. Their habitat gets taken for farms, their bodies for dinner and their heads for trophies. As human populations grow, the pressure increases, and it seems to decline only when people are rich enough to focus on the aesthetic as well as the economic possibilities of wild

25、 beasts. Often, such aesthetic appreciation thrives best in the safety of the city rather than in the rawness of the wilderness.1. _Africa and Asia are continents where wildlife is under particular pressure. Their human populations are growing and their people are not yet prosperous enough to make c

26、onservation a higher priority than simply getting by in life. But many of the worlds endangered mammals live in Africa and Asia. In North America, by contrast, rural populations are shrinking, people are rich enough to care about wildlife, and many of them do. Moreover, most of the large North Ameri

27、can mammals that existed when humanity arrived in the continent are now extinct. Their ecological niches are therefore wide open for occupation. What could be more logical, Mr. Donlan suggests, than introducing endangered Old World mammals into the New World, thus saving them from extinction while r

28、eturning wild America to something like the state it was in before Homo sapiens took up residence?2. _Although none of the animals Mr. Donlan and his colleagues propose introducing are the same species as the ones that went extinct, many are related and all would fill similar ecological niches. Elep

29、hants, for instance, would help to preserve the grassland by eating shrubs that encroach on it - a role previously filled by mastodons. Lions and cheetahs would control the populations of horses, asses and camels much as their sabre-toothed cousins once controlled similar ungulates.3. _Many mainstre

30、am conservationists are naturally (in more than one sense of that word) suspicious. Chris Haney, a conservation biologist at Defenders of Wildlife, a voluntary conservation group, fears the effort might detract from what he describes as “more realistic“ goals, such as the reintroduction of wolves, b

31、ison, grizzly bears and North American elk (not to be confused with the European sort, known to Americans as moose). These reintroductions have faced bitter opposition from some ranchers, farmers and politicians. If programmes like this were seen not merely in isolation, but as the first steps in a

32、grand plan to reintroduce lions and cheetahs, they would be even harder to implement.4. _Both of these objections are sensible, though not overwhelmingly so. But Dr. Haney has a more visceral worry, too. Modern conservation is generally against the idea of species being spread into novel habitats, a

33、nd he opposes Mr Donlans idea on those grounds, as well.5. _Perhaps it is, although such pollution does happen naturally from time to time. But even if such introductions are not the ideal solution, they may be the best one available. Mr. Donlans idea is a big and imaginative proposal to solve a cle

34、ar and present danger. It is certainly worth some careful scrutiny.A Mr. Donlans plan is to create game reserves of a quarter of a million hectares or more in the Great Plains of North America, and populate them with a mixture of native American and alien animals. If returned to grassland, the plain

35、s could support both grazers and their predators. Beginning gradually on small, private reserves, wild horses, asses and camels would be introduced and biologists could study their effects on the ecosystem. Later, if all had gone well, elephants would be added and finally, to provide predators, big

36、cats. If everything worked on a small scale, the large public nature reserves envisaged as the plans culmination would then be created. Mr. Donlan reckons that the whole process would take about 50 years. “It is important“, as he puts it, “to realise that were not advocating backing up a van full of

37、 cheetahs and kicking them out the door.“B Eric Dinerstein, chief scientist at the World Wildlife Fund US, another conservation charity, has a related objection. He suggests Mr Donlans idea might be damaging not only to efforts to conserve North American species, but also to the very Old World speci

38、es it is intended to save. He thinks Mr. Donlan is too pessimistic about the chances of preserving endangered animals in their African and Asian homes. Rather than spending money to establish those species in North America, Dr.Dinerstein would prefer to see it spent conserving them where they live n

39、ow.C Observing all this, a group of conservation biologists, led by Josh Donlan of Cornell University, have made a modest proposal in this weeks Nature. They suggest a piece of ecological arbitrage.D One reason conservationists try to stop alien introductions is pragmatic - they sometimes do serious

40、 damage to native species. Rats, cats and pigs, for example, have wrecked the native fauna of many a small island. But part of the objection to alien introductions has an ideological flavour. There is a feeling that what exists now (or, at least, what existed before man stuck his oar in) is what oug

41、ht to exist. It is pristine. Shipping in other species is, in a sense, a form of pollution.E When the first immigrants entered North America at the end of the Pleistocene epoch, more than 13,000 years ago, they found a continent full of large mammals - elephants, lions, cheetahs, camels, horses and

42、more. Within a few thousand years most of these animals were gone, probably the victims of overhunting.F In theory, the return of the big mammals would result in more diversity throughout the ecosystem. It would also, the researchers suggest, bring tourists flocking to the Great Plains and provide a

43、n alternative income for people there. That may sound fanciful. But, as Mr Donlans paper points out, there are already some 77,000 large exotic mammals, most of them African or Asian species, roaming freely on private ranches in Texas and, in some cases, attracting paying customers.（分数：10.00）填空项 1:_
