Climate change has caused rising sea levels to encroach the once abundant marshes in South Carolina. These marshes are home to a variety of species that could become extinct if not preserved, while also functioning as a wind buffer for the shore during hurricanes. The Southern Bastion acts as a medium on the marsh-sea boundary, with the goal of printing artificial reefs from its lab to gradually develop reefs along the border, reducing erosion and restoring the once-thriving marsh ecosystem. The architecture is also designed to float, minimizing disruption to the fragile ecosystem.
