5203 |aFrom the microcosm in a drop of pond water to the life-sustaining ecosphere, nothing exists solely in and of itself. Every species on earth interacts with the air, water, land, and biota that surround and sustain it in a single web of life. This beautifully designed hardcover book is a valuable resource to Canadians of all ages who are concerned about what is happening to our world and what we can do about it. Through colour photographs, charts and easy-to-read descriptions, we learn how accelerated rates of deforestation, desertification, soil erosion, ozone depletion, and steadily increasing levels of air and water contaminants are diminishing the earth's ability to sustain, not only ourselves, but the millions of other species with whom we share this fragile globe.
