" A mother giving birth in spring spends the last stage of her pregnancy in winter, when she will eat less vitamins than in summer, " said one of the scientists. "When she stops breast-feeding and starts giving her baby normal food, it's in the hot weeks of summer when babies have tendency to infections of the digestive system. " In Austria, adults born in autumn lived about seven months longer than those born in spring, and in Denmark adults with birthdays in autumn outlived those born in spring by about four months. In the southern hemisphere, the picture is similar. Adults born in the Australian autumn lived about four months longer than those born in the Australian spring. The study focused on people born at the beginning of the 20th century, using death certificates and census data. Although nutrition (营养) at all times of the year has improved since then, the seasonal pattern persists.
The passage is mainly about______.
A.how the month of birth is related to life expectancy
B.how the seasonal pattern affects the health of new-born babies
C.how nutrition in different seasons influences life expectancy
D.why people born in autumn are free from chronic illness
In 2004, only about 524,000 salmon are thought to have returned to the spawning grounds, barely more than a quarter the number who made it four years earlier. High water temperatures may have killed many. The House of Commons also lambasted the federal Department of Fisheries and Oceans (DFO) for poor scientific data, and for failing to enforce catch levels. Four similar reports since 1992 have called for the department's reform. In vain: its senior officials are "in denial" about its failings, said the committee.
Mr. Williams' report added a more shocking twist. He concluded that illegal fishing on the Fraser river is "rampant and out of control", with "no go" zones where fisheries officers are told not to confront Indian poachers for fear of violence. The judge complained that the DFO withheld a report by one of its investigators which detailed extensive poaching and sale of salmon by members of the Cheam First Nation, some of whom were armed.
Some First Nations claim an unrestricted right to fish and sell their catch. Canada's constitution acknowledges the aboriginal right to fish for food and for social and ceremonial needs, but not a general commercial right. On the Fraser, however, the DFO has granted Indians a special commercial fishery. To some Indians, even that is not enough.
Both reports called for more funds for the DFO, to improve data collection and enforcement. They also recommended returning to a single legal regime for commercial fishing applying to all Canadians.
On April 14th, Geoff Regan, the federal fisheries minister, responded to two previous reports from a year ago. One, from a First Nations group, suggested giving natives a rising share of the catch. The other proposed a new quota system for fishing licences, and the conclusion of long-standing talks on treaties, including fishing rights, with First Nations. Mr. Regan said his department would spend this year consulting "stakeholders" (natives, commercial and sport fishermen). It will also launch pilot projects aimed at improving conservation, enforcement and First Nations' access to fisheries.
