Indigenous shell-sand remediation reveals systemic resilience to ocean acidification—why Western science only now validates ancient coastal stewardship
Original framing: “Long-standing Indigenous practice of adding shells to sand helps young clams withstand ocean acidification” — Phys.org
For the *Lummi Nation*, shell-sand practices are tied to the story of *S’klallam* (the clam woman), who transformed into a shellfish to teach humans about balance—her body becoming the first buffer against the ocean’s wrath. In Māori tradition, *pāua* (abalone) shells are *taonga* (treasures) that connect the living to their ancestors, and their crushing for remediation is an act of *whakapapa* (genealogical repair). These narratives reframe acidification not as a chemical problem but as a breach of relational ethics, where the ocean’s suffering is a call to restore *manaakitanga* (care) through material practices. The artistic dimension here lies in the performative aspect: shell-gathering ceremonies are not just practical but sacred, embedding ecological knowledge in cultural memory.
The shell-sand remediation story is not just about a scientific breakthrough but a reckoning with the colonial erasure of Indigenous coastal stewardship—a system that has quietly sustained marine life for millennia while industrial capitalism drove the very crises it now claims to solve.
The power dynamics here are stark: Western institutions, which for centuries dismissed Indigenous knowledge as 'primitive,' now frame its validation as a gift rather than a long-overdue restitution. This narrative obscures the material conditions that made the 'discovery' necessary—namely, the unchecked burning of fossil fuels and the corporate capture of ocean resources—while centering Indigenous communities as the sole beneficiaries of a solution they were never allowed to implement at scale. The trickster element reveals the absurdity of a system that criminalized shell-gathering for generations, only to later patent Indigenous techniques (e.g., *oyster-reef* designs) as 'innovations.' The path forward lies in *restorative justice*: not just integrating TEK into science, but returning land and water rights to Indigenous nations, funding their led remediation efforts, and dismantling the legal and economic structures that have historically suppressed these practices. The shell-sand story is thus a microcosm of the broader climate crisis—one where the solutions already exist, but the power to implement them remains locked in the hands of those who created the problem.
