Legendary marine scientist Sylvia Earle portrays a planet teetering on the brink of irreversible environmental crisis.In recent decades we’ve learned more about the ocean than in all previous human history combined. But, even as our knowledge has exploded, so too has our power to upset the delicate balance of this complex organism. Modern overexploitation has driven many species to the verge of extinction, from tiny but indispensable biota to magnificent creatures like tuna, swordfish, and great whales. Since the mid-20th century about half our coral reefs have died or suffered sharp decline; hundreds of oxygen-deprived "dead zones" blight our coastal waters; and toxic pollutants afflict every level of the food chain.Fortunately, there is reason for hope, but what we do—or fail to do—in the next ten years may well resonate for the next ten thousand. The ultimate goal, Earle argues passionately and persuasively, is to find responsible, renewable strategies that safeguard the natural systems that sustain us. The first step is to understand and act upon the wise message of this accessible, insightful, and compelling book.

    Passed through, negotiated, unnamed, ignored, the edgelands have become the great wild places on our doorsteps, places so difficult to acknowledge they barely exist. Edgelands forms a critique of what we value as 'wild', and allows our allotments, railways, motorways, wasteland and water a presence in the world, and a strange beauty all of their own.Paul Farley and Michael Symmons Roberts - both well-known poets - have lived and worked and known these places all their lives, and in Edgelands their journeying prose fuses, in the anonymous tradition, to allow this in-between world to speak up for itself. They write about mobile masts and gravel pits, business parks and landfill sites in the same way the Romantic writers forged a way of looking at an overlooked - but now familiar - landscape of hills and lakes and rivers. England, the first country to industrialise, now offers the world's most mature post-industrial terrain, and is still in a state of flux: Edgelands takes the reader on a journey through its forgotten spaces so that we can marvel at this richly mysterious, cheek-by-jowl region in our midst.
