Fifteen years later, its waters were again teeming with life. A 2009 study found fish biomass had increased by 463%, to a level similar to that of reefs that have never been fished.

Harvard biologist E.O. Wilson proposed setting aside 50% of the planet for nature in his 2016 book, “Half Earth.” But is protecting half of the planet doable?

Success in habitat protection will depend on governments looking beyond the “easy metric” of area to the harder one of effective management.
