Fishing adds only about one percent to the global economy, but on a regional basis it can contribute extremely to human survival. Marine fisheries contribute more to the world’’s supply of protein than beef, poultry or any other animal source. Fishing typically does not need land ownership, and because it remains, generally, open to all, it is often the employer of last resort in the developing world―an occupation when there are no other choices. Worldwide, about 200 million people rely on fishing for their livelihoods. Within Southeast Asia alone, over five million people fish full-time. In northern Chile forty percent of the population lives off the ocean. In Newfoundland most employment came from fishing or servicing that industry ― until the collapse of the cod fisheries in the early 1990s left tens of thousands of people out of work. Though debates over the conservation of natural resources are often cast as a conflict between jobs and the environment, the restoration of fish populations would in fact boost employment. Michael P. Sissenwine and Andrew A. Rosenberg of the U. S. National Marine Fisheries Service have estimated that if depleted species were allowed to rebuild to their long-term potential, their sustainable use would add about ＄ 8 billion to the U. S. gross domestic product ― and provide about 300 000 jobs. If fish populations were restored and properly managed, about twenty million metric tons could be added to the world’’s annual catch. But restoration of ecological balance, fiscal profitability and economic security will require a continual reduction in the capacity of the commercial fishing industry so that wild populations can recover. The necessary reductions in fishing workforce need not come at the expense of jobs. Governments could increase employment and reduce the pressure on fish populations by guiding subsidies away from highly mechanised ships. For each ＄ 1 million of investment, industrial-scale fishing operations require only one to five people, while small-scale fisheries would employ between 60 and 3 000. Industrial fishing itself threatens tens of millions of fishermen working on a small scale by depleting the fish on which they depend for subsistence. The animal source which provides the most protein for human being is_______.

The cohesiveness(内聚力)of a family seems to rely on members sharing certain routine practices and events. For a growing share of the American labor force, however, working shifts beyond the normal daylight hours―what we here call "shiftwork" ― makes the lives of families difficult. Existing research shows that both male and female shiftworkers express high levels of stress and a sense of conflict between the demands of work and family life. But shiftwork couples still maintain a traditional attitude about the meaning of marriage and the individual roles of husband and wife. They expressed a willingness to do" whatever it takes" to approximate their view of a proper marriage, including sacrificing sleep and doing conventional things at unconventional hours. For the majority of couples interviewed ― even when wives worked outside their homes a proper marriage is characterized by a very clear division of roles: husbands are "providers" whose major responsibility is to support the family; wives are "homemakers" who clean, cook, and care for husbands and children. As couples encountered shiftwork schedules, however, initial expectations about what it would take to create a marriage and family were put to test. One woman expressed her dreams about what marriage was supposed to be: "It would make me feel like I had more of a home atmosphere, you know. That’’ s the way I always expected being married having the husband go off, come in the evenings and spend the rest as the evenings together, you know that’’s the way we thought it would be. It doesn’’t work out that way. The women’’s definitions of a "good husband" are typified by the following wife’’s response: I him to be a good provider, and be there when I need him, loyal about the same things as he would expect out of me, expect that I expect him to dominate over me. But in a manner of speaking when it’’s time to be a man I expect him to stand up instead of sitting back expecting me to do everything. To husbands, a good wife was someone who was. Understanding of what I feel go through at work. I need that respect at work, I hope I get it at work. I want my wife to realize what I expect at work. I don’’t want her to give me a lot of shit when I come home from work because ― I don’’t know if this makes much sense. These views seemed critical to maintain the families of the shiftworkers. In order to continue the marriages of the Shiftworkers,______.

Your’’re off work and hanging out at home. Off your diet and into cookies, big dinners and champagne. Off your schedule, and up nights with movies, videos or a good book. Off your workout routine and skipping your morning swim or evening run. In short, you’’re off, free of responsibilities and pressure, stuffed full of food and fun. And you don’’t like it. "All humans, and for that matter all species that are vertebrates and many that are not, have internal clock mechanism, "said George Brainard, professor of neurology at Thomas Jefferson University in Philadelphia." That’’s not a metaphor. It’’s an actual biological entity." As many people find themselves in the second week of enforced indolence because of the winter break -- whether because of school holidays or time off from work -- more than a few may be experiencing a peculiar sensation. A wave of discontent at the luxury of doing nothing, of sitting around with time to spare, the commodity of the late 20th century that we’’re constantly told is in dangerously short supply. The sense is that you should feel great, but actually you don’’t. You hate to admit it, but it might even be a welcome break to go back to work or school. "I enjoy being off, but I enjoy coming back too, "said Virgina Woodard of Chicago. After several days off around Christmas, she was back at her baby-sitting job on New Year’’s Eve, taking her 3-year-old charge to a museum. "It messes up your schedule, and coming back is tiresome," said Woodard, who nonetheless said she enjoyed her time off. "I feel like I’’ll need a week to recover to get back on my schedule, "said Joni Lederer. She and her family shared the holidays at their Highland Park home with another family, and she has spent the days since taking her two sons skating ,bowling and to museums. "Most people," said Brainard," do better and are healthier if they keep a regular social calendar to their life that is somewhat consistent with their internal timekeeping mechanism." The changes in routine that commonly occur during the holidays come at a biological cost. Those changes disrupt the body clock, located primarily in the brain, and may produce an out-of-sorts feeling. "Normal day-to-day routines and realities are very supportive of the internal clock structure that leads to good health," he added. Why is coming back to work tiresome
