Cristina Mittermeier is the marine biologist and activist who pioneered the concept and field of conservation photography. Mittermeier founded the International League of Conservation Photographers (ILCP) in 2005 to provide a platform for photographers working on environmental issues. In 2014, Mittermeier co-founded SeaLegacy, a non-proﬁt organization dedicated to the protection of the ocean. SeaLegacy harnesses the power of communications technology to educate and inform the world about the incredible beauty of the ocean, and all of the challenges that it faces in the wake of the climate crisis. In 2020, on the fiftieth anniversary of Earth Day, Mittermeier announced the most ambitious project of her career: Only One, a new collective of organizations that uses digital technology and visual storytelling to catalyze lasting cultural change, with the ultimate goal of conserving the world's oceans from now into perpetuity. Mittermeier is a Sony Artisan of Imagery and was named one of National Geographic's Adventurers of the Year in 2018. She is also the recipient of many awards, including the Mission Award from the North American Nature Photography Association, the Smithsonian Conservation Photographer of the Year Award, and the Imaging Award for Photographers Who Give Back.
