How to prevent mass extinction in the ocean using AI, robots and 3D printers

The ocean is the most defining physical feature of Earth, covering 71% of the surface of this planet. It is home to incredible biodiversity, ranging from microscopic bacteria and viruses to the largest animal on Earth, the blue whale. We still do not know how many species live in the ocean, but the disappearance of an increasing number of them suggests that extinction is taking place, perhaps at a faster rate than on land. The stakes for ocean biodiversity have never been higher than they are this decade, and now more than ever, we need results. A widely promoted target is to bring 30% of marine area under protection by 2030--a major step that will contribute a great deal to marine biodiversity.
