Oxygen levels on Earth are rapidly declining, and researchers need to find a replacement to sustain life. Earth | Oxygen shortage | Science Technology | Science News | Malayalam Tech News

Oxygen is essential for life on Earth. All living things, including humans, need oxygen to breathe. But the researchers say that Earth’s oxygen levels are rapidly declining. This is according to a study published in the journal Nature Geoscience, titled The Future of Atmospheric Oxygen on Earth. The study predicts that oxygen in Earth’s atmosphere will only exist for the next 100 billion years.

Currently, 21 percent of the Earth’s atmosphere is oxygen. Oxygen is necessary for living things, small and large, just like humans. However, at the beginning of Earth’s history, oxygen levels were very low. However, studies show that they are likely to decline again in the distant future.

Due to the phenomenon of oxygen depletion, there is no near challenge. The researchers also say that such a phenomenon could take up to 100 billion years. If the oxygen disappears, the Earth will return to its previous state of 240 billion years. Scientists also say that the shelf life of oxygen cannot be accurately predicted.

Kazumi Osaki of Toho University in Funabashi, Japan, and Chris Reinhardt of the Georgia Institute of Technology in Atlanta modeled Earth’s climate, biology, and geography from climate change.

According to the report, the oceans on the Earth’s surface will dry up in 240 million years due to increased radiation. At the same time, he warns that as the level of oxygen decreases, its potential will increase four million times and that radiation will kill life on Earth. Oxygen depletion is a major challenge for organisms. Therefore, scientists suggest that another biological particle that could support life on Earth should be replaced by oxygen.

Summary in English: Most life on Earth will die from lack of oxygen in a billion years
