UNESCO has officially inscribed the Prehistoric Shell Middens of the Atlantic Seaboard as a transnational World Heritage Site. These massive archaeological deposits, spanning coastal regions from Florida to Brazil, provide an unparalleled 5,000-year record of human maritime adaptation and biodiversity changes in the Atlantic Ocean.
The designation highlights the cultural significance of these 'anthropogenic islands,' which were used as burial grounds, ceremonial centers, and defensive structures. Experts believe the site will attract new funding for climate resilience, as rising sea levels currently threaten to erode these fragile layers of human history.
