Beneath the surface of the modern Pacific lies the ghost of a far more abundant world — one where sharks patrolled these waters in numbers twenty times greater than today. Paleontologists, reading the geological record like a long and patient letter from the past, have reconstructed a prehistoric ocean whose ecological richness dwarfs what we now take as normal. This finding invites us to reconsider the ocean not as a fixed reality but as a living system with a deep history of transformation — and to ask what that history might teach us about the choices still before us.

Limited direct near-term consumer impact. Long-term implications include potential scarcity of shark-derived products (squalene, collagen), possible increases in seafood prices if shark populations continue declining, and higher costs for marine conservation efforts funded through taxes or consumer goods.
Likely to strengthen marine conservation regulations, shark fishing restrictions, and marine protected area expansion. May drive investment in sustainable fishing practices and alternative materials to replace shark-derived products. Could influence international maritime policy and ocean governance frameworks.
