What would happen if oxygen on Earth suddenly doubled?

If one day in the future, the concentration of oxygen on the earth suddenly doubles, I think such a situation will be a great disaster for us human beings.

By that time, most humans will die of oxygen; Similar prehistoric giants will gradually appear, and the vegetation will grow very tall and stout.

The earth is a large ecosystem, and the state of all species today is only after our "Mother Earth" has been set, and there are a variety of organisms today.

If today's oxygen concentration were doubled, the planet would undergo these terrible changes:

1. Human beings are on the verge of extinction and the current human body is simply unable to survive in an oxygen-rich environment. In the case of increased oxygen concentration, we humans will die quickly, and in large quantities.

At this time, the high-altitude area will become more suitable for human survival, just because the oxygen in the high-altitude area is scarce at this stage, and at that time, the oxygen concentration in the high-altitude area will increase, and it may become the only place for people to live.

2. Giant plants and animals appeared hundreds of millions of years ago, and there was an oxygen-rich period, which is also known as the Carboniferous Period. At that time, the concentration of oxygen was twice as high as it is today, or even more than twice as much.

The long-term oxygen-rich environment makes many organisms huge, and the corresponding plants also grow very large in the oxygen-rich environment.

Most of the giant centipedes, toads, and giant dragonflies we see in science fiction films today are inspired by the Carboniferous period.

3. Fires, frequent occurrences, and we all know that oxygen has the effect of fueling combustion, and in high concentrations of oxygen, combustion will become more intense and thorough.

Therefore, when the concentration of oxygen increases, the earth is also very prone to forest fires. Moreover, the high concentration of oxygen will also make the fire out of control.

It is our blessing that we are able to live on Earth today, and it is also a gift from Mother Earth. We humans should be grateful for nature and be in awe of it.

Organisms that survive in a hypoxic state die, and the organisms that survive become enormous. Oxygen is the most important thing that affects the world, and its content determines the evolutionary direction of the ecosphere.

What would happen if the oxygen on Earth suddenly doubled?

If the oxygen on the planet suddenly doubles, it will cause many organisms on the planet to grow wildly. Even some plants grow very tall.

If, one day in the future, the concentration of oxygen on the planet suddenly doubles, I think this situation will be a great disaster for us humans.

What would happen if oxygen doubled on Earth?

Many people know that people will die from lack of oxygen, but in fact, people with too much oxygen can also die of poisoning.

The Earth's atmosphere is made up of a variety of gases, the highest of which is nitrogen – about 77% of the total air; followed by oxygen, which accounted for 21%; The remaining 2% is mainly composed of small amounts of gases, including argon, carbon dioxide, helium, neon, krypton, xenon, carbon monoxide, and nitrous oxide. In addition, the air contains an indefinite amount of water vapor.

It is true that the survival of human beings is inseparable from oxygen, because oxygen is a necessary exchange for the metabolism of the human body. If there is a lack of oxygen, the body's functions cannot function properly. Babies born prematurely are usually placed in a nursery with a higher oxygen level because their lungs are not fully developed and their respiratory function is not perfect.

The oxygen content in the incubator is usually 30% to 40%, which is much higher than the 21% in the air. Babies with severe breathing disorders are sometimes given an oxygen mask to prevent insufficient oxygen supply to the brain, allowing them to breathe 100% of the oxygen.

But too much oxygen is also very dangerous. Too much oxygen in the incubator can increase the amount of oxygen in the baby's blood, and too much oxygen can damage the blood vessels in the baby's eyeball, resulting in vision loss or loss.

In addition, when oxygen in the air is mixed with other elements (e.g., hydrogen, carbon), chemical reactions usually occur, and these reactions are called oxidation reactions. In oxidation reactions, usually some of the most basic organic molecules that make up life are broken down.

Excessive oxidation leads to premature aging, and if you do antioxidant maintenance, aging can come later. In fact, there are very few substances that can be absorbed through **, and many of those substances that can resist oxidation are macromolecules, even if you wipe them on your face, they can't be absorbed through **. But the body is different, as long as the antioxidant homework can be persistent, the external ** can show the effect, including melasma** pigmentation can be reduced.

If there is a sudden increase in oxygen, the earth will be affected by the high oxygen environment, the metabolism of organisms and the oxidation rate of cells will be accelerated, which will lead to accelerated aging and death of organisms; and the increased amount of oxygen in the atmosphere will inevitably increase the risk of fires, which will be more difficult to extinguish; And drastic changes in oxygen concentrations could lead to the extinction of many species.

The oxidation of the earth will be very serious, some things and some buildings will oxidize very quickly, some anaerobic organisms will be affected, and if the oxygen concentration is particularly high, it will cause poisoning.

The impact is that some species may die out in a short period of time, and some animals and plants may die because of this rapid change in a short period of time.

If there is a sudden surge in oxygen, many animals and plants on the earth will not be able to stand such high concentrations and will die.

The earth should not be able to bear it, because the current state is the best state, and too much oxygen is actually not conducive to the development of the earth.

If the amount of oxygen in the Earth's atmosphere were to increase dramatically, say, by a doubling of the amount, the following would happen.

Our atmosphere contains about 20% oxygen and about 78% nitrogen。Although oxygen is not the most important part of our atmosphere, it is.

90% of our body's energy comes from oxygen, with the rest coming from food and water. Without oxygen, we can't do anything. That's because you won't live. Moreover, oxygen is not only essential for humans, but it is essential for all life on Earth.

Now, what would happen if the amount of this critical element of the planet doubled?

The first thing we notice is probably those giant insects. Insects breathe through thin tubes called trachea. Scientists speculate that insects such as spiders and cockroaches would grow larger if more oxygen entered these tubes.

About 300 million years ago, in prehistoric times, the Earth's atmosphere contained 30% oxygen. During that time, insects were much larger.

Humans will see fewer diseases, and you will call in sick less. An infection-fighting immune cell called neutrophils occurs more often, making you healthier. You'll have a lot fewer colds!

However, the increased amount of oxygen your body gets can also lead to some serious long-term health problems.

As the oxygen level increases, so does the chance of oxygen toxicity in humans. It occurs when humans are exposed to higher levels of oxygen than their bodies are normally accustomed to. Over time, this can lead to lung damage, vision loss, and an inability for cells to multiply.

Too much oxygen in the body can produce free radicals. These atoms look for other electrons to pair with. When this happens, it can cause damage to your body and DNA.

The more oxygen in the atmosphere, the easier it will be for everything to catch fire. In general, a fire cannot be lit because of a lack of oxygen.

With more oxygen, you'll see how easy it is for everything to catch fire. Think California's forest fires are bad? These are expected to happen all over the world. Even moist vegetation has a chance to burn.

The earth is likely to be destroyed, because if there is more oxygen, people will not be able to breathe normally, and it will also cause plants to have no way to photosynthesize, and it will also cause people to die, animals to die.

The earth will be full of life, people will be very healthy, life will be very long, people will be everywhere, and people will be very efficient in doing their work.

It is likely to cause biological oxygen poisoning on the earth, and it will also cause some plants or humans to be killed, and there will also be a lot of natural fires, which will probably lead to some forest fires.

Many organisms will be poisoned, and there will be a lot of natural disasters, mainly because many things have changed in the process, but the only good thing is that the tumor disease will slowly decrease.

Fires are too numerous to control. This is the simplest ending, due to the rise in the amount of oxygen, many of the original sparks can really ignite the prairie fire, and any environment with a high temperature to a certain level may be brewing a shocking fire that cries ghosts and gods. The large-scale action of fires could lead to a decline in the cover of much of the earth's vegetation.

Of course, the burned forest will be restored faster, and the burned forest itself will be a distribution center for nutrients, and the ability of surface recovery will be improved. ‍‍

In the history of the earth, there have been many times when the oxygen content in the atmosphere has increased dramatically, and each increase in oxygen has brought about a sudden increase in the size and number of organisms, and the increase in oxygen content has promoted the vigorous development of life on the earth. Some theories suggest that the formation of a large amount of oxygen in the Earth's atmosphere was about 2 billion years ago, at the end of the Ice Age, when the Earth began to warm up, and various organisms such as cyanobacteria that can produce photosynthesis began to multiply, and oxygen continued to rise from a very low level, eventually forming an oxygenated atmosphere. And with that came the first sprint of life on Earth.

Compared to their ancestors, which did not have a nucleus, new organisms with a complete nucleus can be tens of thousands of times larger. ‍‍

The metal and bridges around me are aging and rusting at an accelerated rate. Another process in which oxygen accelerates oxidation is slow oxidation. Like a metal bridge or something.

The increase in oxygen levels will lead to some large buildings, such as the Eiffel Tower and the Sutong Bridge, which require higher maintenance costs and more frequent maintenance every year.

Oxygen is so active that it can cause significant damage to living tissues, the greatest impact of high oxygen levels is that human lifespan is reduced, and free radicals (i.e. O2-) are thought to exacerbate the aging process through oxidative stress, which interferes with many cellular physiological and biochemical processes: protein synthesis, DNA replication, cell-to-cell signaling, and is also thought to be responsible for multiple sclerosis, geriatric diseases, Parkinson's disease and many other diseases. Oxygen, the energy gas of life, is also the cause of life degradation, disease, and eventual death.

The most obvious change is the mega-sizing of organisms, where oxygen made up 35% of the air about 300 million years ago. Dragonflies, the oldest insects in the class, evolved about 350 million years ago, and fossils know that dragonflies are much larger because they benefit from increased oxygen levels, and their wingspan at that time was about a foot. That's why there are large animals like mammoths and dinosaurs.

As oxygen levels drop, large-sized animals cease to exist. So if the oxygen is doubled, the animals will also become larger, which will cause the animals of the earth to return to the prehistoric stage.

In addition to some anaerobic bacteria, water and oxygen will basically become the breeding ground for the birth of species. With more oxygen, new species can be brewed and produced faster. When the time comes, any flying fish, a dog that can change color, or something, can appear, but don't be afraid.

In the era when dinosaurs began to appear, the oxygen content in the air reached 35%, and some insects at that time were several times larger than the current size, such as some dragonflies up to one meter long, and other insects are several times the size of the same species of insects today, and the huge size of dinosaurs is also said to be related to the sufficient oxygen content.

If the oxygen burst is too large, such as doubling, it will lead to the extinction of a large number of mammals, and natural fires will not be extinguished, and in the long run, some species that can adapt will evolve into new species to adapt to the new oxygen-containing environment. Insects may benefit the most, and the Earth may become a world ruled by giant insects.

Another result of the increase in oxygen is the increase in humidity in the earth's atmosphere, because when the hydrogen ions blown out by the solar wind hit the oxygen atoms on the earth, water molecules will be formed, and when a large number of hydrogen atoms and oxygen atoms form water molecules, then the humidity of the earth's atmosphere will increase.
