The rich resources of Pacific kelp forests helped humans populate the Americas. Now depleted by as much as 95 percent, they need our help to recover.

The elks, in turn, devoured the vegetation, triggering a trophic cascade or ecosystem collapse. The loss of prey often forces predators to find new food sources, which can have unpredictable ...
