But can industrial mining really succeed in removing the nodules from depths of four thousand metres? What will happen to the deep-sea ecosystem if man reaches this last untouched part of the Earth?
We accompany scientists on the research vessel SONNE during their expedition to the so-called Manganese Nodule Belt in the Pacific Ocean, where they search for answers that may determine our future.
