What will happen to the earth when it runs out of oxygen?

Until the process of loss of consciousness and brain damage begins, man can survive for only 4 minutes without oxygen, and death can occur after 6 minutes, leading to the failure of the biological process that feeds the cells. ۔ Cells

“The loss of oxygen is at an extreme level of survival. The human body does not have an abundant supply of oxygen, only a few liters, and how you use it depends on your metabolic rate.” BBC Future.

According to Tipton, at rest, an adult consumes one-fifth to one-fourth of a liter of oxygen per minute, and this can increase to four liters per minute if they are engaged in any activity. Anxiety and stress play a major role in boosting the metabolic rate, so people, for example, cannot survive without water in their bodies.

A study published in March 2021 Nature bioscienceScientists predict that in about a billion years, the earth will run out of oxygen, turning the planet into a huge ball of barren rock. What will happen when that happens?

Villain and good man

A 31-page scientific paper by Cornell University experts was published in the journal. Astronomy, Revealed that the process of depletion of the Earth’s air will be slow and gradual rather than overnight. It’s part of his own past, after all, there was no oxygen on the planet in the beginning.

After 3.8 billion years, when the surface was cold enough to cool, early life emerged only a few million years later. However, the atmosphere was still nothing more than a harmful mixture of gases like methane and ammonia, which are now deadly to human life. Science believes that oxygen in the oceans is formed as a by-product of cyanobacteria during the process of photosynthesis.

The moment the air was filled with the element, the so-called great oxidation event occurred, a catastrophe that made the air more lethal with oxygen, causing a band of rust to get trapped in the geological record due to over-enrichment.

The sun was responsible for shaping the planet’s atmosphere into today’s environment, helping to create complex life. However, the irony is that he is the one who can kill the earth in the future.

What’s going to happen

Before the sun enters the final stages of its life, turning into a huge red star that will devour Mercury and Venus before burning everything in its path, the earth is already destroyed by its heat. Would have been

University of Toronto Institute of Technology’s Juliana Sackman and Kathleen Kramer show in their research New scientists, Which has become 30% brighter since the sun shone 4.5 billion years ago. Over the next billions of years, it should shine another 10%, which would be too much for our planet, which could face a smoke-like, barren, suffocating fate like Venus.

Oxygen will begin to be affected by the sun due to the rocks, which are responsible for regulating the environment through the carbonate silicate cycle, switching between the atmosphere and carbonate minerals. This will be disturbed by high levels of sunlight, which will cause the planet’s rocks to absorb more CO.give Compared to their return.

Although very slowly, as more carbon dioxide gets trapped in the rocks, there will be less space for plants to photosynthesize in the Earth’s atmosphere, resulting in a catastrophic reduction in the world’s oxygen levels. This will be the beginning of deforestation, which will die with more light, creating a desert of branches on the surface of the planet.

The oceans will be the only ones that will sustain the photosynthesis process for a long time, however, they will not be able to withstand the heat of the sun’s rays. Thus, they will enter a state known as the “wet greenhouse”, the effect of the vapor climate is considered a death sentence for a planet.

There is a long debate about whether humanity will last long enough to see the planet die. We have to live a thousand times longer for that, and by then 300,000 years will have passed on Earth.

However, even if that happened, the civilization of that time would certainly already have enough resources and intelligence to go to any other corner of the solar system or beyond.
