Art Wolfe s definitive opus, Earth Is My Witness represents forty years of expeditionary photography. For the first time, Wolfe presents the three subjects at the heart of his work landscapes, wildlife, and cultures on the edge of extinction in a single masterpiece. His images take us through the world s ecosystems and geographical regions in a vivid display of the fragility and interconnectivity of life on Earth, while simultaneously exploring his evolution as an artist and the techniques he uses to capture the nuances and rhythms of nature. Setting the stage for this fascinating journey is award-winning author and National Geographic Society explorer-in-residence Wade Davis. Together, Davis and Wolfe present a world that borders on the fantastic but is all the more precious for its fragility. At the heart of Wolfe s work is the appeal for environmental, cultural, and wildlife preservation, which he makes here with beautiful, far-reaching precision.
