When we think about the source of Earth’s oxygen, forests and trees usually come to mind first. But a huge share of the planet’s oxygen production is happening somewhere completely different.
Microscopic photosynthetic organisms in aquatic environments play an enormous role in the chemistry of Earth’s atmosphere. Through photosynthesis, these tiny forms of life connect sunlight, carbon dioxide, water, and oxygen on a truly planetary scale.
It is a remarkable example of how organisms too small to notice individually can collectively influence something as fundamental as the air surrounding the entire planet.
Perfect for anyone curious about oceans, photosynthesis, phytoplankton, algae, Earth science, or the hidden biological systems that help make life possible.
