With the near complete end of commercial whaling, ship collisions are now a leading cause of death worldwide for large whale species, according to new research published in Science.

Yet little is done to manage this risk, found authors of the study, led by the University of Washington.

In a first of its kind global analysis, scientists found that shipping overlaps with 92% of whale ranges, and less than 7% of the hot spots with the greatest collision risk had any management strategies in place to reduce strikes.
