Currently, there are no practical or feasible methods to directly de-acidify the oceans on a large scale. Ocean acidification is primarily driven by the excessive accumulation of carbon dioxide (CO2) in the atmosphere, which is then absorbed by the oceans. The CO2 dissolved in seawater forms carbonic acid, leading to increased acidity.

While it is challenging to reverse ocean acidification directly, there are efforts to explore and develop potential methods to mitigate its effects. These approaches are focused on reducing CO2 emissions and exploring ways to enhance the ocean's natural buffering capacity. Some research initiatives are investigating the feasibility of ocean alkalinity enhancement, which involves adding substances like crushed limestone or silicate minerals to seawater to increase its alkalinity and counteract acidity. However, these techniques are still in the experimental stages and face significant challenges in terms of scalability, effectiveness, and potential unintended consequences.

Therefore, the most effective approach to addressing ocean acidification remains reducing CO2 emissions at their source and implementing strategies to minimize further acidification. This requires global efforts to transition to renewable energy sources, promote sustainable practices, and protect and restore marine ecosystems. By taking action to reduce CO2 emissions and mitigate climate change, we can help prevent further acidification and limit the impacts on marine ecosystems and species.
