单选题Africa's elephants are divided between the savannahs of eastern and southern Africa and the forests of central Africa. Some biologists reckon the forest ones-smaller, with shorter, straighter tusks-may even constitute a distinct species. But not for long, at the latest rate of poaching. The high price of ivory is increasing the incentive to kill elephants everywhere in Africa, and especially in places where there is virtually no law. The latest reports suggest that the forest elephant population is collapsing on the back of rising Chinese demand for ivory. Some conservationists argue that a recent decision by the Convention on International Trade in Endangered Species (CITES) to auction 108 tonnes of stockpiled ivory from southern Africa may be prompting more poaching in central and eastern Africa, as criminals seek to mix illicit ivory in with the legitimate kind. But some economists maintain that the legitimate sale of ivory lowers prices, thus decreasing the incentive to poach. A study of a previous sale of ivory suggested it did not lead to more intensive poaching. Either way, the Congo basin is " hemorrhaging elephants ", says TRAFFIC, which monitors trade in wildlife. The head of the 790,000-hectare (1,952,000-acre) Virunga National Park in eastern Congo, Emmanuel de Merode, reports that 24 elephants have been poached in his park so far this year. The situation is dire: 2,900 elephants roamed Virunga when Congo became independent in 1964,400 in 2006, and fewer than 200 today. Most have been poached by militias, particularly Hutu rebels from Rwanda who hack off the ivory and sell it to middlemen in Kinshasa, Congo's capital, who then smuggle it to China. Once ivory has left its country of origin, and if it is not seized by customs officials, it can be hard to identify its source and those responsible for acquiring it. But forensic help may be at hand. Scientists from the University of Washington are using genetic markers in elephant dung to identify exactly where ivory has been poached. This should help governments in countries such as Tanzania and Zambia, which are capable of catching poachers, but not in anarchic eastern Congo, where 120-odd rangers have been killed in Virunga in recent years trying to protect elephants and gorillas. With an influx of businessmen and other officials from China engaged in infrastructure projects such as road building and logging, the slaughter is expected to accelerate. Forest elephants may survive in large numbers only in remote protected pockets of the Congo basin, such as the Odzala-Koukoua National Park in Congo-Brazzaville and Minkebe National Park in northeast Gabon.

单选题The age of gilded youth is over. Today"s under-thirties are the first generation for a century who can expect a lower living standard than their parents. Research into the lifestyles and prospects of people who were born since 1970 shows that they are likely to face a lifetime of longer working hours, lower job security and higher taxes than the previous generation. When they leave work late in the evening, they will be more likely to return to a small rented flat than to a house of their own. When, eventually, they retire, their pensions are far lower in real terms than those of their immediate forebears. These findings are revealed in a study of the way the ageing of Britain"s population affecting different generations. Anthea Tinker, professor of social gerontology (老人学) at King"s College London, who carried out much of the work, said the growth of the proportion of people over 50 had reversed the traditional flow of wealth from older to younger generations. "Today"s older middle-aged and elderly are becoming the new winners," she said. "They made relatively small contributions in tax but now make relatively big claims on the welfare system. Generations born in the last three to four decades face the prospect of handing over more than a third of their lifetime"s earnings to care for them. " The surging number of older people, many living alone, has also increased demand for property and pushed up house prices. While previous generations found it easy to raise a mortgage, today"s under-thirties have to live with their parents or rent. If they can afford to buy a home it is more likely to be a flat than a house. Laura Lenox-Conyngham, 28, grew up in a large house and her mother did not need to work. Unlike her wealthy parents, she graduated with student and postgraduate loan debts of £13,000. She now earns about £20,000 a year, preparing food to be photographed for magazines. Her home is a one-bedroom flat in central London and she sublets (转租) the lounge sofa-bed to her brother. "My father took pity and paid off my student debts," she said. "But I still have no pension and no chance of buying a property for at least a couple of years—and then it will be something small in a bad area. My only hope is the traditional one of meeting a rich man." Tinker"s research reveals Lenox-Conyngham is representative of many young professionals, especially in London, Manchester, Edinburgh and Bristol.
