Sylvia Earle has spent more than 70 years exploring and protecting the oceans. Titouan Bernicot began restoring coral reefs as a teenager and has since built Coral Gardeners into a global conservation movement. The pair join forces as part of the Rolex Perpetual Planet Initiative to share five principles they believe are essential to protecting our oceans, and how we can all play a part. #calltoearth 📸 : 1, 3,: Coral Garderners/Noe Langronier; 2, 8: Rolex/Tim McKenna; 4, 5, 7 : Coral Gardeners/Ryan Borne; 6: Tim Taylor
