Three years ago, a team of marine scientists looked at the global problem of overfishing and came to the grim conclusion that by 2048, populations of all the fish that people around the world eat will have collapsed.
Now, some of those same scientists have joined others to compile a new, more hopeful assessment: Overfishing remains a critical problem, but in some parts of the world, conservation efforts appear to be paying off.
The results suggest that broader use of a small kit of management tools could put global fisheries back on a path to sustainability.
