What breathes more oxygen to the Earth is The Ocean, not Forests

The lungs of the Earth is the ocean.
Phytoplankton in the oceans produces more than half of the air we breathe.

Phytoplankton photosynthesizes and absorbs 37billion tons of CO₂ per year. This is 40% of all CO₂ in the air, which is equivalent to the volume of CO₂ reduced by 1.7 trillion trees (4 times the size of Amazon).

It is said that the CO2 removal capacity of phytoplankton has decreased considerably due to the increase in sea surface temperature over the past 30 years.

With the restoration of marine ecosystem, we can reduce CO₂ that causes climate crises.
