A MAGNIFIED VIEW OF PHYTOPLANKTON
Almost 70 percent of the oxygen we breathe comes from microscopic plant-like organisms called phytoplankton (or microalgae) that live on the surface of oceans and lakes. One type of phytoplankton, Prochlorococcus, produces up to 20 percent of the oxygen found in our entire biosphere. It is so small that millions can fit in a drop of water. These drifting marine organisms photosynthesize, using carbon dioxide, water, and energy from the sun, releasing tonnes of oxygen, a process they’ve been at for billions of years.

The earliest known photosynthesising marine fossil we have a record of goes back 3.5 billion years. The ocean was producing oxygen for billions of years before that. Early in our planet’s history, the atmosphere had almost no oxygen. Oxygen generated as a byproduct by photosynthesizing microbes eventually built up in the atmosphere, drastically changing our planet’s environment and the history of life in the process.

Land plants evolved from green marine algae, so we owe the ocean for all of the oxygen that comes from them as well. These submerged algae raised their heads above water once the atmospheric oxygen levels were high enough for the ozone layer to form, protecting them from lethal levels of UV radiation that pervaded the planet. Only one-third of the Earth’s oxygen comes from the green cover on land.
