For Earth Day, CBS interviewed James Balog, environmental photographer, founder of Earth Vision Institute, and INSTAAR Affiliate. Balog has become one of the foremost chroniclers of human-caused climate change, as his cameras have tracked the dramatic effects – vanishing ice, rising seas, fires, and the toll climate change is taking on all living things. As shown in the 6-minute video interview, ~1200 of his prints were recently acquired by the Library of Congress.
