Reduce whale-ship strikes by making 2.6% of ocean surface safer, study says

Researchers identify collision hotspots around world but reveal almost all these lack preventive measures

Collisions between whales and ships can prove fatal for the marine mammals, but researchers say expanding mitigation measures to just 2.6% of the ocean's surface would reduce the chance of such strikes in all risk hotspots.

While experts say many whale-ship collisions go unobserved and unreported, making it difficult to put a figure on the scale of the problem, some estimates suggest tens of thousands of the animals are killed each year.
