The ocean produces more oxygen than all the trees on Earth combined? Tiny marine organisms, primarily phytoplankton, generate 50% to 70% of the oxygen we breathe through photosynthesis. These microscopic life forms quietly power our planet’s atmosphere, creating the oxygen we depend on daily.

Rainforests, including the Amazon, contribute around 28% of Earth's oxygen, but the ocean remains our largest oxygen producer. However, it's not just about oxygen production—marine ecosystems also consume oxygen, creating a delicate balance that sustains life on Earth.
