Conclusion & Applications. Data & Observations. Introduction. Different species respond to low levels of pH differently: some of the test subjects were . For tens of millions of years, Earth's oceans have maintained a relatively stable acidity level. It's within this steady environment that the rich and varied web of life in today's seas has arisen and flourished. But research shows that this ancient balance is being undone by a recent and rapid drop in surface pH that could have devastating global consequences.. Damian C. Brady, Ph.D.. Ira C.

The . law of . conservation of mass. . implies that mass can neither be created . Key understanding. 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 .
