Due to the use of unsustainable energy, ocean acidification is a rising problem for marine ecosystems. The high levels of pH (acidity) in the water alters the natural chemical bonding process in regards to the building of shells and exoskeletons of marine wildlife. The rising level of . An Taisce. . April 2013. Ocean Acidification. Even if continuing levels of CO2 were not an issue in generating climate change, its impact on ocean acidification would require the same level of international action to reduce and cap emissions to scientifically acceptable limits..
