The majority of the world’s oxygen is generated in the oceans, particularly by marine phytoplankton. These minuscule organisms, such as algae and cyanobacteria, play a vital role in oxygen production through the process of photosynthesis.
It is estimated that marine phytoplankton contribute to the production of approximately 50-85% of the oxygen in our planet’s atmosphere. This is because oceans cover about 70% of the earth’s surface, making them a vast and significant habitat for oxygen production.
Phytoplankton are tiny plants that float near the top of the ocean. They are incredibly plentiful and varied, and they utilize sunlight to transform carbon dioxide (CO2) and water (H2O) into oxygen (O2) and organic carbon through photosynthesis. This process releases oxygen into the water and eventually into the air.

In addition to oxygen production, phytoplankton have a vital role in the global carbon cycle. They absorb carbon dioxide from the atmosphere and utilize it for their growth, thereby reducing the amount of carbon dioxide in the air. This process aids in controlling the earth’s climate by diminishing the greenhouse gas impact.
While forests and other land-based vegetation also play a role in oxygen production, they cover a smaller area compared to oceans. Therefore, although they are crucial for local oxygen levels and biodiversity, they do not contribute as much oxygen to the global scale as marine phytoplankton.
Marine phytoplankton, through their activity, play a crucial role in the production of oxygen on our planet. Their photosynthetic processes greatly impact the oxygen we inhale and are vital in preserving the equilibrium of our planet’s atmosphere and climate.
