With a goal of photographing every wild animal in zoos around the world, Joel Sartore has documented more than 6,000 already, and thanks to a partnership with National Geographic, he may reach his goal. Showcasing more than a hundred lush color portraits, this cleverly arranged collection includes a Florida grasshopper sparrow, a greater one-horned rhinoceros, a sloth, a blue-spotted charaxes butterfly, and a spectacled owl. With an introductory essay by Douglas Chadwick and an inspiring foreword from Harrison Ford, this book presents a thought-provoking argument for saving all the species of our planet.
