Oxygen is essential for life on Earth. Every living thing, including humans, needs oxygen to breathe. But researchers say the Earth’s oxygen levels are declining rapidly. This is according to a study published in the journal Nature Geoscience, entitled The Future of Atmospheric Oxygen on Earth. The study predicts that oxygen in the Earth’s atmosphere will only exist for the next 100 billion years.
At present, 21 percent of the Earth’s atmosphere is oxygen. Oxygen is needed for living things, small and large, 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 oxygen depletion phenomenon, there is no near-challenge. Researchers also say that cats need to be included in any precautionary measures against the virus. If oxygen disappears, the Earth will return to its previous state of 240 billion years. Scientists also say that the lifespan of oxygen cannot be accurately predicted.
Kazumi Osaki of the University of Toho in Funabashi, Japan, and Chris Reinhardt of the Georgia Institute of Technology in Atlanta modeled the Earth’s climate, biology, and geography on 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, it warns that as the level of oxygen decreases, its potential will increase by four million times and that radiation will wipe out life on Earth. Oxygen depletion is a major challenge for organisms. Therefore, scientists suggest that another biological particle that could sustain life on Earth should be replaced by oxygen.
English Summary: Most life on Earth will be killed by lack of oxygen in a billion years
