Oxygen began building up in the prebiotic atmosphere at approximately 1.85 Ga during the Neoarchean-Paleoproterozoic boundary, a paleogeological event known as the Great Oxygenation Event (GOE). At current rates of primary production, today's concentration of oxygen could be produced by photosynthetic organisms in 2,000 years. [4]

Stage 4 is known as the neoproterozoic oxygenation event. The Neoproterozoic Oxygenation Event ( NOE ), also called the Second Great Oxidation Event , was a geologic time interval between around 850 and 540 million years ago during the Neoproterozoic era , which saw a very significant increase in oxygen levels in Earth's atmosphere and oceans ...
2 began to accumulate in the atmosphere about 2.5 billion years ago during the Great Oxygenation Event, about a billion years after the first appearance of these organisms. [83] [84] An adult human at rest inhales 1.8 to 2.4 grams of oxygen per minute. [85] This amounts to more than 6 billion tonnes of oxygen inhaled by humanity per year. [g]
