California and the Pacific Northwest lost vast stretches of their kelp forests to warming waters, sea urchin explosions, and decades of ecological neglect. Now a scrappy coalition of fishermen, divers, tribal nations, and marine scientists is fighting to bring them back — and the results are starting to look like a miracle.
