Historical Study Reveals Lost Oyster Reefs Once Spanned Europe

Research uncovers the vast extent of European oyster reefs, now functionally extinct due to overfishing and pollution.

Oyster reefs once covered at least 1.7 million hectares across Europe, from Norway to the Mediterranean.
These reefs supported rich biodiversity, providing habitats for nearly 200 fish and crustacean species.
Oysters played crucial roles in shoreline stabilization, nutrient cycling, and water filtration.
Historical records show the rapid destruction of these ecosystems, leading to a 'flattening' of seafloors.
Restoration projects are underway, but researchers call for increased support to revive these vital ecosystems.
