About this Book
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 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 colourful history of commercial fishing and hunting, 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 travellers, 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
commercialisation of the seas.
The story does not end with an empty ocean. Instead, Roberts describes how we might restore the splendour 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.
