Does this math add up? Protecting 4% of the #ocean could save most of the planet's marine mammals #biodiversity

You might have heard of the 80/20 rule. It says that in many cases, you can get about 80% of the result for 20% of the effort. Well, according to a study published in the Proceedings of the National Academy of Sciences, something similar might apply to the protection of marine mammal species. Of the 129 species of marine mammals on Earth, including seals, dolphins and polar bears, about 1/4 are facing extinction, but most of them could be saved if we could protect just 4% of the planet's oceans (obviously, more than 4% would be even better!).
