For seven decades, Sir David Attenborough has traversed the globe documenting the diversity of Earth’s ecosystems. In a Q&A with National Geographic, the legendary 99-year-old discusses his new documentary special and shares why he wants us to confront the ocean's ongoing destruction—if only to inspire us to save it.

TUNE IN:  Ocean with David Attenborough begins airing on National Geographic June 7 and streams globally the next day, World Oceans Day, on Disney+ and Hulu. The film is in cinemas in select countries outside the U.S.
