They Released 15 Sea Otters Into a Crab-Dominated Marsh — 20 Years Later, Nobody Saw This Coming
Sea otters were hunted to near extinction — their recovery reveals an astonishing truth about coastal ecosystems. Discover how a single keystone species, thought to be gone forever, reversed the physical collapse of an entire California coastline through nature's hidden machinery. This documentary follows the 100-year mystery of Elkhorn Slough: Why did engineers fail to stop coastal erosion despite millions in investment? The answer lies 40 feet underwater, where sea otters were beginning an unexpected comeback. Through groundbreaking research and natural experimentation, scientists uncovered a trophic cascade nobody predicted — one where a predator's hunger, measured in crabs, holds the foundation of a coastline together. Watch how nature's solution outperformed human engineering, and learn what it reveals about the invisible forces holding our coasts in place. =================================== 👉 What do you think of this video?
