The graph above is exhibiting how the ocean’s pH levels have change over the recent centuries. In the recent years, the pH level has decreased from being basic to being more acidic. The pH level in the 1800’s were about 8.2 and now they have decreased to be 8.1 due to the mass burning of fossil fuels. This has caused scientist to classify it as acidic.
