Script by Hubert Reeves, David Vandermeulen - Art by Daniel Casanave

In a voyage of discovery that takes us to the bottom of the sea, Hubert Reeves explains how the oceans formed, what makes them salty, and what causes currents and tides. He reveals the wonders of life below the waves and shows us how the oceans can determine the very future of our precious planet. This is why they need our protection.
