Don't tell that to your local sushi chef. Over the past three decades, the fish export trade has grown fourfold, to 30 million tons, and its value has increased ninefold, to $ 71 Billion. The dietary attractiveness of seafood has stoked demand. About 90% of the ocean's big predators like cod and tuna--have been fished out of existence. Increasingly, fish and shrimp farms are filling the shortfall. Though touted as a solution to overfishing, many of them have--along with rampant coastal development, climate change and pollution devastated the reefs, mangroves and seagrass beds where many commercially valuable fish hatch.
Steven Murawski, chief scientist at the U. S. National Marine Fisheries Service, finds Worm's headlining prediction far too pessimistic, Industry experts are even more skeptical "There's now a global effort to reduce or eliminate fishing practices that aren't sustainable," says industry analyst Howard Johnson. "With that increased awareness, these projections just aren't realistic."
Perhaps. Still, the destructive fishing practices that have decimated tuna and cod have not declined worldwide, as Johnson suggests. Up to half the marine life caught by fishers is discarded, often dead, as bycatch, and vibrant coral forests are still being stripped bare by dragnets. Worm argues that fisheries based on ecosystems stripped of their biological diversity are especially prone to collapse. At least 29% of fished species have already collapsed, according to the study, and the trend is accelerating.
what's a fish eater to do？ "Vote with your wallet," says Michael Sutton, who runs the Monterey Bay Aquarium's Seafood Watch program in California. Since 1999, the aquarium has handed out pocket guides listing sustainably harvested seafood. The Marine Stewardship Council has partnered with corporations to similarly certify wild and farm-raised seafood. Some 370 products in more than two dozen countries bear the British group's "Fish Forever" label of approval. Wal-Mart and Red Lobster, among others, have made commitments to sell sustainably harvested seafood.
But that's just a spit in the ocean unless consumers in Japan, India, China and Europe join the chorus for change. "If everyone in the U. S. started eating sustainable seafood," says Worldwatch Institute senior researcher Brian Halweil, "it would be wonderful, but it wouldn't address the global issues. We're at the very beginning of this."
It can be inferred from the first paragraph that ______.

The idea that government should regulate intellectual property through copyrights and patents is relatively recent in human history, and the precise details of what intellectual property is protected for how long vary across nations and occasionally change. There are two standard sociological justifications for patents or copyrights: They reward creators for their labor, and they encourage greater creativity. Both of these are empirical claims that can be tested scientifically and could be false in some realms.
Consider music. Star performers existed before the 20th century, such as Franz Liszt and Niccolo Paganini, but mass media produced a celebrity system promoting a few stars whose music was not necessarily the best or most diverse. Copyright provides protection for distribution companies and for a few celebrities, thereby helping to support the industry as currently defined, but it may actually harm the majority of performers. This is comparable to Anatole France's famous irony, "The law, in its majestic equality, forbids the rich as well as the poor to sleep under bridges." In theory, copyright covers the creations of celebrities and obscurities equally, but only major distribution companies have the resources to defend their property rights in court. In a sense, this is quite fair, because nobody wants to steal unpopular music, but by supporting the property rights of celebrities, copyright strengthens them as a class in contrast to anonymous musicians.
Internet music file sharing has become a significant factor in the social lives of children, who download bootleg music tracks for their own use and to give as gifts to friends. If we are to believe one recent poll done by a marketing firm rather than social scientists, 48%o of American Internet users aged 12 to 17 had downloaded music files in the past month. In so doing, they violate copyright laws, and criminologists would hypothesize they thereby learn contempt for laws in general. A poll by the Pew Internet and American Life Project found that two-thirds of an estimated 35 million Americans who download music files do not care whether they are copyrighted. Thus, on the level of families, ending copyright could be morally as well as economically advantageous. On a much higher level, however, the culture-exporting nations (notably the United States) could stand to lose, although we cannot really predict the net balance of costs and benefits in the absence of proper research. We do not presently have good cross-national data on file sharing or a well-developed theoretical framework to guide research on whether copyright protection supports cultural imperialism versus enhancing the positions of diverse cultures in the global marketplace.
It will not be easy to test such hypotheses, and extensive economic research has not conclusively answered the question of whether the patent system really promotes innovation. Vie will need many careful, sharp focus studies of well-formed hypotheses in specific industries and sectors of life. For example, observational and interview research can uncover the factors that really promote cultural innovation among artists of various kinds and determine the actual consequences for children of Internet peer-to-peer file sharing.
