These studies suggest ocean acidification, driven by increased atmospheric CO2, negatively impacts marine biodiversity by affecting survival, calcification, growth, reproduction, and predator detection, leading to decreased biodiversity in some habitats, community shifts, and ecosystem restructuring.

Ocean acidification, driven by the absorption of anthropogenic carbon dioxide (CO2) by seawater, is a significant environmental issue with profound implications for marine biodiversity. This process results in lower pH levels and altered carbonate chemistry in the oceans, affecting various marine organisms and ecosystems.

Ocean acidification poses a substantial threat to marine biodiversity, primarily through its negative effects on calcifying organisms and the degradation of biogenic habitats. The variability in organism sensitivity, combined with physiological and behavioral changes, can lead to significant shifts in marine ecosystems and food webs. These changes have far-reaching consequences, not only for marine life but also for human societies reliant on coastal and marine resources. Addressing ocean acidification requires urgent and sustained efforts to reduce CO2 emissions and mitigate its impacts on marine ecosystems.
