Callum Roberts – författare

Reef Life is the story of how Callum Roberts, Britain's pre-eminent marine conservation scientist, fell in lovewith coral reefs and embarked on a thirty-year career. He began as a young university student who had neverbeen abroad, spending a summer helping to map the unknown reefs of Saudi Arabia. And from that moment,when Callum first cleared his mask, he's never looked back, moving on to survey Sharm El Sheikh, and fromthere diving and researching all over the world, including Australia's imperilled Great Barrier Reef and the more resilient reefs of the Caribbean.His stories are astonishing, lyrical and laced with a wonderful wry humour - and they allow us privilegedaccess to, and understanding of, the science of our oceans and reefs. Reading this book will also commitreaders to support Callum's goal to get marine reserve status for ten percent of the world's ocean.

Their depths remain largely unexplored, yet ninety-five percent of the planet's habitable space lies within them.

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.
