Hans Silvester's dramatic photographs of water in its many forms combine with a lyrical text on water's infinitely mysterious nature to produce this glowing tribute to a life-giving substance that occupies three-quarters of our world's surface area. Silvester's spectacular photography of both placid and turbulent bodies of water, of geysers and glaciers, of clouds ready to burst and snow about to melt, are among the most sublime images of water ever gathered in one volume. Authors Bernard Fischesser and Marie-France Dupuis-Tate discuss the scientific properties and sources of water in a series of chapters which reflect on water as the sculptor of the landscape, and deliver a powerful environmental message about the dangers of polluting the Earth's water supply. Their essays and Silvester's glorious images offer a rhapsodic apprecation of this elusive, omnipresent, ever-changing and indispensable substance that forms and animates life on earth.
