Art Wolfe’s conservation photography career has spanned five decades. His goal has always been to win support for conservation issues by “focusing on what’s beautiful on the Earth.” Wolfe, who has authored an impressive number of published books, has a new one available now: “Earth Is My Witness is the most extensive collection of Art Wolfe photography ever compiled. This lavishly produced work spans the globe, bringing the beauty of the planet’s fast-disappearing landscapes, wildlife, and cultures into stunning focus.” Read an interview with Wolfe here on Smithsonian.com.
