Joel Sartore is committed to documenting every animal in captivity with a focus on the growing list of endangered species and those facing extinction circling the globe, visiting zoos and wildlife rescue centers to create studio portraits of 12,000 species. Paired with the eloquent prose of veteran wildlife writer Douglas Chadwick, and with a foreword by Harrison Ford, Sartore s animal portraits are riveting: from tiny to mammoth, from the Florida grasshopper sparrow to the greater one-horned rhinoceros. Now, with the accelerating pace of climate change and its devastating effect on wildlife habitat, his book presents a more urgent argument for saving all the species of our planet.
