Prior state
Wild-capture fisheries remained a major global protein source despite progressive depletion of many stocks.
Material change
Aggregate wild marine biomass available for commercial harvest crossed a permanent lower threshold; global protein supply reorganized around aquaculture, terrestrial alternatives, and synthetic or cellular systems.
Why now
The early-century window captures the cumulative effect of twentieth- and twenty-first-century extraction pressure plus climate-driven productivity shifts.
Mechanism and resistance
Physical stock decline forced regulatory and market substitution; resistance came from coastal fishing communities, distant-water fleets, and cultural attachment to wild seafood.
Consequences
Coastal livelihoods in many lower-income regions contracted; protein prices and trade patterns shifted toward controlled production systems. Biodiversity loss in marine systems became a standing ecological feature.
End state
Wild-capture marine protein no longer constituted a primary pillar of global food security.
Observable test
Sustained multi-decade decline in global wild-capture marine tonnage relative to early-twenty-second-century peaks, accompanied by formal institutional recognition of permanently lower harvest ceilings.
Disconfirming sign
Recovery of major commercial stocks to twentieth-century abundance levels sufficient to restore prior harvest volumes.
