At a time when we are more aware than ever of the vulnerability of the earth and the uncertainty of its future, this important book is at once timely and stunningly beautiful. WWF Global 200 identifies the world's most critical and endangered natural sites. Magnificent photographs, presented in large-scale format, depict a diverse range of global ecoregions, conveying the unique characteristics of each region and the threats to each, and demonstrating the need for us to take action now to preserve these irreplaceable natural resources.Vibrant full-color photographs transport the reader to the East African Acacia savannas which are home to an exceptional diversity of large land mammals and birds threatened by poaching, agriculture, land use conflicts with pastoralists, and uncontrolled trophy hunting. The reader will visit the Patagonian Steppe, one of the largest single habitats in the world, and home to a number of threatened and endangered endemic species, and learn the sobering reality of this largely unprotected region. From the forest of Borneo to the Hawaiian forests and marine ecoregion, from the Siberian taiga to the Antarctic Peninsula and the Weddell Sea, this volume demonstrates the beauty, fragility, and inestimable significance of ecoregions around the world. Conservationists, nature lovers, fine-photography aficionados, and armchair travelers alike will appreciate the superb photography and urgent message of this call to action.
