Scientists explain when Earth will run out of oxygen.

Changes in atmospheric conditions on Earth: the end of oxygen

Scientists predict that in a billion years, conditions on the planet Earth will change so much that oxygen will run out. Astronomers from Toho University in Japan and NASA have found that the breathable atmosphere will be destroyed long before the global destruction of the planet itself.

The sun is aging, and with it comes more heat. As it burns brighter, the surface of the Earth warms up, water evaporates, and the carbon cycle that supports photosynthesis begins to break down. Plants die, oxygen production halts, and Earth slowly returns to a hell with high methane content and low oxygen levels.

In the 4.5 billion years of Earth's existence, significant changes have occurred, from a molten magma sphere to the development of life and the appearance of supercontinents. Scientists emphasize that the concentration of carbon dioxide in the atmosphere will increase even more if humanity does not stop using fossil fuels.

Flooding cities:

Other studies also show that the 28 most densely populated cities in the USA are sinking under water at a rate of two to ten millimeters per year. The city of Venice has already sunk by 25 centimeters over the last century, and sea levels continue to rise. Italy has already developed an action plan to save this unique city.
