The World Atlas of Biodiversity is an updated edition of Global Biodiversity: Status of the Earth's Living Resources, originally published in 1992 and reissued in 2000 as Global Biodiversity: Earth's living resources in the 21st Century. This 2002 edition, totally redesigned and updated, includes new data and graphics, additional photos, and additional material on food issues and biodiversity, as well as an entirely new chapter on protected areas and other conservation issues.

World Atlas of Biodiversity addresses the remarkable growth in concern at all levels for living things and the environment, and increased appreciation of the links between the state of ecosystems and the state of humankind. Building on a wealth of research and analysis by the conservation community worldwide, this book provides a comprehensive and accessible view of key global issues in biodiversity. It outlines some of the broad ecological relationships between humans and the rest of the material world and summarizes information on the health of the planet. Opening with an outline of some fundamental aspects of material cycles and energy flow in the biosphere, the book goes on to discuss the expansion of this diversity through geological time and the pattern of its distribution over the surface of the Earth, and trends in the condition of the main ecosystem types and the species integral to them.
