Wondrous, enchanting, threatened, The Natural World as seen through the eyes of celebrated photographer Thomas D. Mangelsen chronicles ten distinct ecosystems that serve as islands of refuge for the human spirit and the animals that make their home there. By the man American Photo magazine calls One of the 100 Most Important People in Photography, Mangelsen takes the viewer on a visual odyssey as he documents his subjects within the context of their many and varied environments. Excerpted from his journals detailing his experiences in the field, Mangelsen’s words provide a window into the man behind the camera as he shares his love for and fascination with the places that have changed his life and perspective on our shrinking planet.
