Imagine that by some miracle the Earth was left without oxygen for 5 seconds. What happened? Well, people can hold their breath for longer periods, but what about the planet?
Take a deep breath. You inhale oxygen, which occupies about 21% of the earth's atmosphere, and 78% is nitrogen. Although it is not the most common gas in the atmospheric layer, it is considered essential for life.
5 seconds seem trivial, because many without breathing can last 30 seconds or more. Therefore, such a short lack of oxygen can go unnoticed for your body. And if we consider the situation on the scale of a planet that has completely lost its oxygen element (imagine that it does not exist at all)?
It would take just 5 seconds to completely change the planet. Without oxygen, you can say goodbye to the Hoover Dam and other structures built of concrete. These structures will collapse instantly. The fact is that oxygen acts as a binding agent for concrete. Without oxygen, concrete turns to dust.
By the way, any raw metal will immediately fuse. The bottom line is that there is an oxidation layer on metals that does not allow them to fuse. If at this time you sunbathe on the beach, you risk getting burned. The ozone layer (the main protection from sunlight) is made of oxygen (three bound oxygen atoms). If oxygen disappears, the Earth will become very hot. By the way, you will not only burn. Most likely, your inner ear will burst. Loss of oxygen will result in a loss of 21% air pressure. Such a sharp jump can be compared with a descent to a depth of 2000 m below sea level. Ears do not have time to adapt.
And that's not all. Without oxygen, there will be no fire, so only electric vehicles will remain on the move. No luck, if at this time flew on an airplane, because it will fall. The sky will be incredibly dark. Before being on the ground, sunlight is reflected from a multitude of particles in the air. Without oxygen, the sky will lose these particles and darken.
Oh, by the way, until all this happens, the crust is completely destroyed, because it is 45% oxygen. It turns out that you, having received multiple burns, an exploded inner ear and a dark sky, will go into a free fall, watching the Earth fall apart in some 5 seconds without oxygen (although you yourself will decay, because oxygen will disappear in the body). Fortunately, this scenario will never come true. But now you know what you have to go through.
