What If Oxygen Levels Doubled In The Earth's Atmosphere?

The incredibly super cool must see American sci-fi film Starship Troopers we watch with a sinking heart as these huge alien arachnid beetles suck the brains out of their human prisoners and send asteroids hurtling down upon the earth. Of course, this is pure fantasy. 

But what if someday a mosquito the size of an airplane could attack and bite us? Or if beetles the size of tanks wandered our city streets?

Actually, we wouldn't even have time to think about being frightened as a global Inferno will already have begun engulfing most planetary life in its path. So what event could actually turn insects into giant mutants and set fire to the entire planet? The answer to this question is in the air, literally, at present, the atmospheric gas envelope around our planet contains about 20% oxygen with most of the room Major being nitrogen at 78%.








If we open up some kind of cosmic oxygen valve, and doubled the amount of oh two to 40%, everything would change more than you could possibly imagine. For example, cars would be able to drive almost without any fuel at all. paper airplanes launched by young school children would glide far beyond the horizon, and many of the animal and insect inhabitants of our planet would thrive on this extra oxygen quickly evolving up to unprecedented sizes.

According to scientists at first, this would apply to insects and some arthropods, such as spiders, there's spiracles these are kind of like breathing holes due to the excess oxygen will evolve to greatly expand and their bodies will swell like balloons.

About 300 million years ago, the Earth's atmosphere was 30% oxygen at that time, judging fossil remains, insects and arthropods were much much larger. If you double the current percentage of oxygen, then they should evolve to even much larger sizes than in antiquity. In such a case, it cannot be excluded from the realm of possibility that lot cucaracha cockroaches the size of rats would soon be found in people's homes, you spiders, the size of ravens would begin to lower in the noxious network of flies. What If Spiders Had Wings? This is another story.

Now the size of hawks and many of the other inhabitants of our planet will not be lagging too far behind. Flowers could soon be on par with modern trees and size. Well, the trees themselves, such as poplars and spruce will fight each other as they reach up into the clouds for human beings. Each of our 23,000 daily breaths will add enormously to our strength as with this super audience.

Oxygenated atmosphere 90% of the energy we consume will be from this newly abundant oh two, and only 10% of our energy will we need to draw from water and food. Over time, humans will evolve into two meter tall giants who, for example, will be able to achieve incredible records in sports that were previously unthinkably unattainable. Humans will also become smarter and more attentive as the brain receives more oxygen.

In our bodies, there will also be a much larger number of neutrophils, cells that destroy viruses and bacteria. Due to this, everyone will acquire a kind of ironclad immunity, fearless in the face of almost any infection. So might we really become some kind of super people? Well, yes, and no, this vastly increased amount of oxygen will also unforce snidely oxidize more of the environment, creating more of those nasty bugbears called free radicals.

Free radicals. For those who don't know, damage DNA and increased susceptibility to cancer. There will also be an increase in incidences of oxygen poisoning. Yes, you heard that right, too much oxygen is bad for you. And this much, too will be more than a body needs, at least before we evolved to handle it.

Over time. Too much oxygen can lead to lung disease, a loss of vision, and the retardation of a cell's ability to multiply. However, if we could somehow reduce the atmospheres pressure itself, all these troubles could be avoided.

For example, when in a spacesuit with low pressure, astronauts breathe almost pure oxygen and nothing bad happens, they suffer no ill effects and have no complaints regarding their health. But unless everyone could suddenly start wearing spacesuits all day and every day, then our planet would have to be covered under an atmosphere of significantly lower pressure for us not to endure and abundance of hardship.

And it looks like quite the opposite would happen with our doubled Oh to first the atmosphere of the planet will become much denser and second, it will begin to scatter and diffuse more sunlight. As a result, less vapor will be released into the air and the environment will further oxidize, destroying multitudes of living things, plants, animals, insects, you name it. Finally, our men made products will suffer as well.

Any metal products will rust much faster and most organic materials will age lickety split, and a top it off. Anything that doesn't have time to grow old in a flash or become smothered in rust and corrosion will begin to burn with an excess of oxygen substances that can even begin to ignite in a normal environment can flare up like a torch with all this extra to around even the damp, humid vegetation of the tropics will burn like dry kindling, the mega fire that roared for weeks in California in 2018. Devouring more than 100,000 hectares of land will look like some sort of campfire in comparison. So yeah, it turns out that a bunch of excess oxygen isn’t such a good thing like you might have think before.

 On the flip side, what might happen if all oxygen just disappeared? 

Well, okay, almost everything would die. Let's tone it down a little and imagine what would happen if all oxygen disappeared for just a very short period of time. Really short, let's say, five seconds. That can't really hurt Canada. Let's investigate. No one obviously is going to have to ride around in a fit of suffocation.

It's just Five seconds, and our bodies don't really respond to oxygen deficiency anyway, but to high levels of carbon dioxide, it would take much more than five seconds for this concentration to become critical. But for those who happen to be outside, like sunbathing on the beach, for example, the sun is going to roast them instantaneously like toast.

The reason is that our planets ozone, which consists of three oxygen atoms, and makes up the eponymous ozone layer will stop blocking ultraviolet light. And for those Earth inhabitants, not on beaches, are they going to be okay?

No, they're still in for a doozy of a day. First, everyone's inner ear will explode as the atmosphere will lose about 21% of its pressure in an instant. However, there'll be nothing to listen to anyway, due to the lack of oxygen, all cars which use internal combustion engines that are dependent on oxygen will stall, their engines will simply stop turning, and those that are already moving will immediately coast to a stop.

Planes just taking off will crash to the ground. And airplanes already in the sky will be able to glide through the air for a while. As they tried to restart their failed engines. All communications including the internet will likely crash and disappear. Worst of all, you won't be able to watch the latest riddle video or pretty much anything at all. The cells in our bodies contain a lot of water, h2o, and guess what water is made from?

That's right, hydrogen and oxygen. When the oxygen disappears, all that will be left is the hydrogen gas which will float up in the way. In fact 75% of the elements of which we are composed will collapse.

So that all that will be left above will be just a trace of nitrogen, carbon and phosphorus, the sky will turn black due to a sharp decrease in particles reflecting light. The crust of the earth, which is almost half oxygen will pretty much cease to exist, the ocean turned into pure hydrogen will almost certainly evaporate up into space, and concrete buildings will instantly turn to dust as its oxygen that binds them together.

In addition, all pieces of raw and manufactured metals will stick to themselves and each other as they are normally kept separate only by an oxidation layer. Yes, all fires will obviously go out without any oxygen to allow them to burn.

But what will happen when the Earth's atmosphere is refilled with oxygen after the five seconds are up something really spectacular, a worldwide continent and oceans spanning exploits Fortunately, at least for the moment, we can home calmly inhale and exhale and rejoice in the fact that our 20% of atmosphere oxygen hasn't gone anywhere just yet. But what about tomorrow?

Geochemist from Princeton University have investigated and figured out what the level of gas has been in our atmosphere over the last many hundreds of thousands of years. To do this, they examined something called ice cores, ancient ice samples obtained from ice sheets in Greenland and Antarctica. These frosty popsicles contain bubbles of air from the ancient past air literally frozen in time, revealing information about the composition of the atmosphere from those prehistoric times.

It turns out that over the past 800,000 years, the level of oxygen on our world has decreased by point 7%. Scientists believe that before the birth of the on our planet many billions of years ago, oh two in the Earth's atmosphere was almost completely absent. Only after the appearance of cyanobacteria did oxygen levels begin to rise.

Then, roughly two and a half million years ago, the amount of oxygen increased dramatically. The researchers suggest that there might have been some major geological event that caused this. It surmise that this event somehow heeded a solid carbon dioxide deposit which had accumulated between the earth's core and its mantle. The end result was a mega explosion that released a stupendous amount of oxygen into the atmosphere. Since then, the ratios of gases in our atmosphere shell have remained basically unchanged.

Only in the last Millennium has there been a kind of oxygen leak? Scientists say that the oh two is evaporating too slowly but this will not significantly affect the climate. However, due to its lack in some places, the ecosystems of our oceans are already being devastated.

Over the past 50 years for example, the number of areas in our oceans with low oxygen content has quadrupled. And in some coastal regions, for example, the Chesapeake Bay or the Gulf of Mexico, these dead zones have become 10 times larger. In the dead zones, the warming of the water has led to an unprecedented growth of algae. They actively consume almost all of the available oxygen and release heat, as well as a variety of toxic substances during decomposition. fish and other marine life simply cannot survive under such conditions. 

Many fish either perish or tried to migrate into the open ocean. In their new and unusual environment. They often become easy prey for predators and fishing. trawlers In addition, emissions of hydrogen sulfide and nitric oxide in such dead zones, almost completely annihilates corals, a US researcher named Daniel Stolper believes that the total oxygen content will continue to fall further and the dead zones under conditions of global warming will only continue to expand to stop this seemingly inexorable process from continuing. 

Stolper proposes reducing emissions of greenhouse gases into the atmosphere and a halt to all ocean dumping. Only then he says, might we be able to save this vital element from disappearing forever?

But Another situation is what would happned if Earth Lost Its Atmosphere? Earth will look like Mars silent and uninhabitable, its human population would not be able to survive without the protective layer. As terrifying as this may sound, it is unlikely to happen soon.
