More than 70 percent of the planet covered by water. Three-quarters of the oceans have a depth of over 800 meters. Here begins the realm of the infinite sea depths beyond our reach.
This unknown world is 90 percent of the habitable space of the planet. We know more about the surface of the moon than about the sea floor. In this eternal darkness, inhabited by strange life forms. Only a few decades ago it was thought that life at these depths is impossible, but today scientists believe that the first life appeared on the bottom of the ocean. Energy, resources, food and even the climate is influenced by oceans. There to decide the future of our planet?
