Ocean acidification is a growing threat to marine life, ecosystems, and human health. Rising atmospheric carbon dioxide (CO2) emissions from human activities, primarily the burning of fossil fuels, are the main drivers of ocean acidification. As atmospheric CO2 levels continue to rise, the ocean’s pH decreases, making it more acidic. This review examines the impacts of ocean acidification on climate and health hazards, focusing on the causes and consequences of acidification, as well as potential solutions. The review discusses how ocean acidification is affecting marine life, including shellfish, corals, and fish, and how this can lead to economic and ecological consequences. Additionally, it explores how ocean acidification is exacerbating climate change and contributing to the occurrence of extreme weather events. The review also examines the potential health hazards associated with ocean acidification, including the impact on human health through the consumption of contaminated seafood, and the impact on mental health due to the loss of natural resources. Furthermore, this review outlines potential solutions to address ocean acidification, such as reducing CO2 emissions, improving wastewater treatment, and implementing sustainable fishing practices. The review concludes that urgent action is needed to reduce greenhouse gas emissions and mitigate the impacts of ocean acidification. It highlights the need for interdisciplinary collaboration to address this issue and underscores the importance of developing sustainable solutions to preserve the health of our oceans and the well-being of human populations worldwide.
