Species’ extinctions in the oceans

“The potential for species’ extinctions in the oceans has been severely underestimated,” Professor Roberts said. “The sea is the least explored part of the planet but holds more than 95% of its living space and a large chunk of the unknown species. New data we review show the same pattern that we see on land of geographical clusters of small range species that are particularly vulnerable to extinction. This is worrying because ocean conservation has been particularly neglected. While nearly 13 percent of Earth’s land area is now protected, only two percent of its ocean is.”
