(ORDO NEWS) — According to experts, absolutely all complex types of organisms will die as a result of a lack of oxygen in the boundless future. If anyone survives, then only bacteria.
Experts told under what conditions oxygen deficiency will come. A team from Toho University in Japan and the Institute of Technology in Atlanta took up the study of this issue. Oxygen levels will drop to a critical level in about 1.08 billion years. The concentration will be about 1%. Such an indicator already took place in early history.
The change will take 10 thousand years. The reason is an increase in the intensity of the sun’s glow. The heat will absorb more and more carbon dioxide, the photosynthesis of plants will be disrupted. This will ultimately affect the oxygen concentration.
The amount of methane in the atmosphere will increase, and the ozone layer will disappear.
Such a disappointing scenario was presented as part of NASA’s Nexus for Exoplanet System Science, a project to study possible life on exoplanets.
