Ocean acidification, driven by increased atmospheric CO2 levels, poses significant threats to marine ecosystems, affecting biodiversity, species interactions, and overall ocean health. As CO2 is absorbed by seawater, it lowers the pH, resulting in detrimental effects on marine life. This study employs a comprehensive meta-analysis of existing literature to assess the ecological consequences of acidification on key marine organisms, such as corals and shellfish, while also examining the broader implications for marine food webs and fisheries. The findings reveal that ocean acidification leads to decreased calcification rates, altered species composition, and disrupted trophic dynamics, which can compromise ecosystem resilience and functionality. Furthermore, these changes may result in economic repercussions for coastal communities reliant on fisheries. This research underscores the urgent need for effective mitigation strategies and informed policy decisions to address ocean acidification. By enhancing our understanding of these impacts, this study highlights the critical importance of preserving marine biodiversity and ensuring the sustainability of oceanic resources for future generations. The results not only contribute to the scientific discourse but also serve as a call to action for stakeholders involved in marine conservation and climate change mitigation efforts..
