What's Ocean Acidification?

Decent Essays
When carbon dioxide (CO2) is absorbed by seawater, chemical reactions occur that reduce seawater pH. This is called “ocean acidification.” Due to the Industrial revolution in the 1800s, the use of fossil-fuels have resulted in billions of tons of Carbon dioxide into Earth's atmosphere (Ocean Acidification). Over time, oceans have absorbed large amounts of the carbon dioxide emitted. On the pH scale, solutions with those with higher numbers are considered basic, while low numbers are considered acidic. On a scale one to 14, seven is neutral. Over the past 300 million years, ocean pH has been close to basic, averaging at about 8.2. Today, it is around 8.1, which indicates a drop of 0.1 pH units. Based on the last two centuries, this represents
