The exploitation of marine resources is causing imbalances in aquatic ecosystems. Many types of seafood and materials originating from the ocean are unsustainable. We must shift towards resources that do not harm, and can regenerate, the ecosystems; such as sea urchins and farmed seaweed.
Sea urchins thrive in the changing ocean with few predators and too many nutrients. They devour the seaweed habitats leaving behind underwater deserts. There are millions of sea urchins in Victoria alone, turning vast areas of a thriving marine ecosystem barren. Can we turn this problem into a resource?
