Ocean Acidification

The ocean is just getting more and more acidic due to the shit (literally and figuratively) we keep pumping into it.  The media tells everyone that the amazon is "the lungs of the earth" but in reality algae in the ocean is responsible for \~70% of the oxygen that gets generated.

Eventually the ocean is going to get too acidic for the algae to survive.

It’s due to carbon dioxide. It’s a chemical reaction. CO2 + H2O gives you H2CO3. Carbonic acid.
