Systemic Collapse of Calcifying Biota & Bio-Mineral Utility Shift

The systemic decline in calcifying marine biota represents a foundational shift in global biogeochemistry and resource valuation. Driven by increasing atmospheric CO2 partial pressures, this trend manifests as ocean acidification, which chemically reduces the saturation state of aragonite and calcite—the primary mineral forms utilized by organisms such as coral polyps, mollusks, and key plankton species (e.g., pteropods). Because biomineralization is a highly sensitive metabolic process, the reduction in available carbonate ions forces these foundational marine ecosystems into chronic stress states, leading to structural degradation and systemic decline across multiple trophic levels.
