Until the loss of consciousness, and the start of the process of brain damage, a person can only live without it Oxygen For 4 minutes, with death occurring after 6 minutes, which leads to the failure of the biological processes that nourish the cells of the body.

“Loss of oxygen is the ultimate in survival. The human body doesn’t have a huge amount of oxygen, just a few liters, and how you use it depends on your metabolic rate.” BBC Future.

According to Tipton, an adult at rest uses between five and a quart of oxygen every minute, and this can increase to four liters per minute if they are engaging in some sort of activity. Panic and stress are contributing factors to an increased metabolic rate, so for example people can’t survive even the least their bodies can handle without air underwater.

A study published in March 2021 in natural earth sciencesScientists predicted that within a billion years, Earth would run out of oxygen, turning the planet into a large ball of barren rock. How will it be when that happens?

The bad guy and the good guy

A 31-page scientific paper by experts at Cornell University, published in the journal astrobiologyrevealed that the process a land Running out of air will be slow and gradual, not overnight. This is part of his past, after all, the planet initially had no oxygen.

After 3.8 billion years, when the surface had cooled enough to become solid, the first life appeared only a few million years later. However, the atmosphere was nothing but a harmful mixture of gases, such as methane and ammonia, which are now deadly to human life. Science believes that oxygen formed in the oceans as a byproduct of cyanobacteria during photosynthesis.

The moment the air filled with the element, the so-called Great Oxidation Event occurred, a catastrophe that rendered the air deadly with excess oxygen, leaving a pool of rust trapped in the geological record due to over-enrichment.

The sun was responsible for shaping the planet’s atmosphere as it is today, aiding in the complex life-forming process. However, ironically, it was he who could end up killing Earth in the future.

What will happen

Before the sun enters its last stages of life, transforming into a massive red star devouring Mercury and Venus before charring everything in its path, the Earth will already be devastated by its heat.

Juliana Sackman and Kathleen Kramer of the University of Toronto Institute of Technology showed in their study that new world Since the Sun was lit up 4.5 billion years ago, it has become 30% brighter. In the next billions of years, another 10% should shine, which would be too much for our planet, which may face the same blazing, barren, stifling fate that Venus.

Oxygen will begin to be affected by the sun due to the rocks responsible for regulating the environment through the carbonate and silicic cycle, switching between the atmosphere and carbonate minerals. This will be interrupted by the high levels of sunlight, which will cause the planet’s rocks to absorb more carbon dioxidetwo of their return.

Albeit very slowly, as more carbon dioxide is trapped in the rocks, the Earth’s atmosphere will be less able to photosynthesize plants, resulting in a catastrophic drop in the world’s oxygen levels. This will be the beginning of the end for the forests, which will die of excess light, forming a desert of boughs on the surface of the planet.

The oceans will be the only ones that will sustain photosynthesis longer, however, they will not be commensurate with the heat of the sun’s rays. As such, they will enter a state known as a “wet greenhouse,” a climatic effect of evaporation that is a death sentence for a planet.

There is a long debate about various ideas about whether humanity will survive long enough to watch the planet die. We’ll have to survive a thousand times longer for that, and by that time it will be 300,000 years on Earth.

However, even if that happened, it was certain that the civilization of the moment already had enough resources and intelligence to move to another corner of the world. Solar System or beyond.
