“It was the first time I’d seen what the ocean may have looked like thousands of years ago.” That’s conservation scientist Gregory S. Stone talking about his initial dive among the corals and sea life surrounding the Phoenix Islands in the South Pacific. Worldwide, the oceans are suffering. Corals are dying off at an alarming rate, victims of ocean warming and acidification—and their loss threatens more than 25 percent of all fish species, who depend on the food and shelter found in coral habitats. Yet in the waters off the Phoenix Islands, the corals were healthy, the fish populations pristine and abundant—and Stone and his companion on the dive, coral expert David Obura, determined that they were going to try their best to keep it that way.

 

Underwater Eden tells the story of how they succeeded, against great odds, in making that dream come true, with the establishment in 2008 of the Phoenix Islands Protected Area (PIPA). It’s a story of cutting-edge science, fierce commitment, and innovative partnerships rooted in a determination to find common ground among conservationists, business interests, and governments—all backed up by hard-headed economic analysis.

 

Creating the world’s largest (and deepest) UNESCO World Heritage Site was by no means easy or straightforward. Underwater Eden takes us from the initial dive, through four major scientific expeditions and planning meetings over the course of a decade, to high-level negotiations with the government of Kiribati—a small island nation dependent on the revenue from the surrounding fisheries. How could the people of Kiribati, and the fishing industry its waters supported, be compensated for the substantial income they would be giving up in favor of posterity? And how could this previously little-known wilderness be transformed into one of the highest-profile international conservation priorities?

 

Step by step, conservation and its priorities won over the doubters, and Underwater Eden is the stunningly illustrated record of what was saved. Each chapter reveals—with eye-popping photographs—a different aspect of the science and conservation of the underwater and terrestrial life found in and around the Phoenix Islands’ coral reefs. Written by scientists, politicians, and journalists who have been involved in the conservation efforts since the beginning, the chapters brim with excitement, wonder, and confidence—tempered with realism and full of lessons that the success of PIPA offers for other ambitious conservation projects worldwide.

 

Simultaneously a valentine to the diversity, resilience, and importance of the oceans and a riveting account of how conservation really can succeed against the toughest obstacles, Underwater Eden is sure to enchant any ocean lover, whether ecotourist or armchair scuba diver.

Humanity can make short work of the oceans’ creatures. In 1741, hungry explorers discovered herds of Steller’s sea cow in the Bering Strait, and in less than thirty years, the amiable beast had been harpooned into extinction. It’s a classic story, but a key fact is often omitted. Bering Island was the last redoubt of a species that had been decimated by hunting and habitat loss years before the explorers set sail.

As Callum M. Roberts reveals in The Unnatural History of the Sea, the oceans’ bounty didn’t disappear overnight. While today’s fishing industry is ruthlessly efficient, intense exploitation began not in the modern era, or even with the dawn of industrialization, but in the eleventh century in medieval Europe. Roberts explores this long and colorful history of commercial fishing, taking readers around the world and through the centuries to witness the transformation of the seas.

Drawing on firsthand accounts of early explorers, pirates, merchants, fishers, and travelers, the book recreates the oceans of the past: waters teeming with whales, sea lions, sea otters, turtles, and giant fish. The abundance of marine life described by fifteenth century seafarers is almost unimaginable today, but Roberts both brings it alive and artfully traces its depletion. Collapsing fisheries, he shows, are simply the latest chapter in a long history of unfettered commercialization of the seas.

The story does not end with an empty ocean. Instead, Roberts describes how we might restore the splendor and prosperity of the seas through smarter management of our resources and some simple restraint. From the coasts of Florida to New Zealand, marine reserves have fostered spectacular recovery of plants and animals to levels not seen in a century. They prove that history need not repeat itself: we can leave the oceans richer than we found them.
