段1：①When prehistoric man arrived in new parts of the world, something strange happened to the large animals: they suddenly became extinct. ②Smaller species survived. ③The large, slow-growing animals were easy game, and were quickly hunted to extinction. ④Now something similar could be happening in the oceans.
段2：①That the seas are being overfished has been known for years...⑤According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) in a new fishery is reduced on average by 80% within 15 years of the start of exploitation. ⑥In some long-fished areas, it has halved again since then.
段3：①Dr. Worm acknowledges that these figures are conservative. ②One reason for this is that fishing technology has improved. ③Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. ④That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes...
段4：①Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. ②They believe the data support an idea current among marine biologists, that of the“ shifting baseline.” ③The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past...

[A] management efficiency.
