We are all part of the ocean space, sailing together on the canoe of the future. Immense, the Ocean has long led us to believe that it was unalterable. However, our actions are already having terrible and irreversible effects, impacting the climate, the beings who populate it, and all those who depend on it, that is to say all of us. In this documentary, Hubert Reeves, with his gentleness, his rigor and his love of life, invites us to discover the Ocean, its threats, its inhabitants and above all its phenomenal resilience as long as we give it time to get well!
