Abstract
With the deepening of globalization, the problem of ocean acidification is becoming more and more serious, posing a threat to the ecology and fishery resources. In this paper, the concept, causes, scientific basis of ocean acidification and its extensive impact on ecosystem services are analyzed, and corresponding solutions are proposed. The paper begins by outlining ocean acidification as a key aspect of global climate change, the main cause of which is rising carbon dioxide concentrations due to human activities. The paper then explores the ocean pH balance, the relationship between carbon dioxide and ocean pH, and how human activities can accelerate this process. Three main impacts of ocean acidification on ecosystem services were analyzed: weakening the Marine carbon sink function, threatening fishery resources, and damaging biodiversity. In response to these issues, the paper proposes a series of strategies, including reducing CO2 emissions, promoting Marine adaptation, establishing monitoring networks, developing new technologies, and promoting a global governance fr amework aimed at mitigating ocean acidification and protecting Marine ecology. Finally, the paper summarizes the main findings of the study and points out shortcomings and directions for future research, highlighting the key role of global collaboration in addressing the challenges of ocean acidification.
