Diving here with @natgeopristineseas was like getting in a time machine and traveling back to the ocean of the past. We spent six weeks establishing a baseline model for healthy coral reefs, diving for more than a thousand hours. Studying pristine reefs like these help us envision what the ocean of the future can look like, if we give nature the space to come back.」7月28日 15時39分
