Via the process of photosynthesis, phytoplankton release oxygen into the water and half of the world’s oxygen is produced via phytoplankton photosynthesis. With the other half produced via photosynthesis on land by trees, grasses and other plants.


New research led by NASA researchers has found populations of the microscopic marine plants, phytoplankton, have decreased in the Northern Hemisphere. An analysis using a NASA model in combination with ocean satellite data between 1998 and 2012, showed a 1% decrease of phytoplankton per year.

Climate change cause ocean acidification as oceans absorb carbon dioxide (CO2) and form carbonic acid (bicarbonate (HCO−3) and carbonate (CO2−3)).

When the PH levels of the oceans are dropping, this will ultimately affect plant-life and wildlife both in the oceans – and above – on land.
