Warming oceans are pushing marine life out of familiar habitats, and as the long-spined sea urchin migrates south to Victoria and Tasmania it is wreaking havoc on ecosystems and commercial fisheries.
Where climate change has created a pest, scientists, designers and divers are finding solutions.
New research promises to turn sea urchin shells into fabric dye, potentially solving an environmental problem and resolving a challenge for commercial divers.
Guests: John Minehan, Victorian sea urchin divers association, and Luis Quijano, Australian Research Council Centre of Excellence in synthetic biology
