6、       A study has warned that seafood supplies from the world’s oceans could be almost gone by the middle of the century .

       Boris Worm of Dalhousie University in Nova Scotia , Canada , led the international team that did the study . Professor Worm says species have recently been disappearing from oceans at increasing speed . At this rate , he says , all seafood species could collapse could collapse by 2048 .

       Other studies have also warned about the dangers of overfishing and the effects on ocean environments . But not everyone thinks the oceans are likely to be empty in fifty tears . Some scientists said parts of the world do have problems , but others are doing a good job of protecting fish populations . Government officals in several countries with large fishing industries also questioned the research .

       The study appeared earlier this month in Science magazine .

       The researchers say damage to oceans affects not only fish populations but also the productivity of ecosystems . These complex systems help control water quality . The scientists say the loss of different kinds of sea life appeared to increase the f fish kills and beach closures from harmful algae growth .

       The scientist examined the results of thirty-two experiments and observed forty-eight protected areas . They also looked at records of catches worldwide . They studied records from the United Nations Food and Agriculture Organization from nineteen fifty to two thousand three . And they examined archeological information and other historical records for twelve coastal areas . That research back over a thousand years .
