Fisheries pressure drastically reduce the fish stock in the Mediterranea Sea
Ocean overfishing is simply the taking of wildlife from the sea at rates too high for fished species to replace themselves. The earliest overfishing occurred in the early 1800s when humans, seeking blubber for lamp oil, decimated the whale population. Some fish that we eat, including Atlantic cod and herring and California’s sardines, were also harvested to the brink of extinction by the mid-1900s.
Highly disruptive to the food chain, these isolated, regional depletions became global and catastrophic by the late 20th century.
In the mid-20th century, international efforts to increase the availability and affordability of protein-rich foods led to concerted government efforts to increase fishing capacity. Favorable policies, loans, and subsidies spawned a rapid rise of big industrial fishing operations, which quickly supplanted local boatmen as the world’s source of seafood.
