How much air does the ocean give us?

The ocean is responsible for producing about 50-80% of the Earth's oxygen, primarily through the photosynthesis of phytoplankton, algae, and marine plants. This vital process plays a crucial role in maintaining the planet's atmospheric balance. While the exact percentage can vary, it underscores the ocean's significance in providing the air we breathe. Protecting ocean health is essential for sustaining this oxygen production.
