Oxygen our main source of life

Imagine if all the Earth's oxygen disappeared, not forever, just for, say seven seconds, would we just hold our breath, What would happen to the atmosphere? What would happen to the environment this is what if and here's what would happen if the world lost oxygen for just seven seconds.

Take a nice deep breath feel how satisfying that is what you're breathing in is oxygen and it takes up roughly 21% of our atmosphere with 78% being nitrogen although it's not the most abundant gas in our atmosphere it is the most important without oxygen plants animals water and us humans wouldn't be where we are today, seven seconds may not sound like a whole lot of time to be without oxygen, most of us can go at least thirty seconds without taking a breath, so it would happen too fast for your body to even notice, your breathing would actually remain normal, but as for everything else not so much in just seven seconds the earth would look completely different, without oxygen you can say goodbye to the Hoover Dam the Pantheon dome and anything else made of concrete these structures would instantly collapse oxygen acts as a special binding agent to concrete without it concrete is just dust speaking of buildings any untreated metal would instantly be fused together, this is because there's a layer of oxidation on metals that prevents them from welding together, without that layer metals would instantly bind to each other, if you happen to be relaxing at the beach at that time, expect a severe sunburn the ozone layer our protection against the sun's UV rays is made of oxygen, take away the oxygen, and the earth would become extremely dangerous, there would be nothing protecting us from the sun's UV rays in addition to a sunburn, our inner ear would explode losing oxygen means losing 21% of our air pressure, a change in air pressure that drastic is equivalent to being at sea level and dropping down 2,000 meters instantly, our ears wouldn't have enough time to adapt.

Having a good time yet well don't expect it to last long, without oxygen there's no fire. The combustion process and vehicles wouldn't be able to occur any mode of transport, that isn't electric will automatically fail, planes will fall from the sky and millions of cars will be stopped in their tracks, the sky would be completely dark before it hits the earth, light from the Sun bounces off multiple particles in the air.

Without oxygen in the atmosphere there are less things to bounce off and the sky will appear dark, Oh yeah, and while all this is happening the Earth's crust would completely crumble, that's because Earth's crust is made up of 45% oxygen the crust would crumble and continue to crumble until there's nothing left, sending you and everyone on the planet into a freefall sound like fun, probably not, but luckily you can take a deep breath of 21% oxygen knowing this will never happen. So now you can relax…that is definitely something that cannot happen, so take a deep breath and be grateful for all the oxygen u can breathe.

But just imagine, how much destruction just seven seconds of not having oxygen can cause. Woah, the destruction is definitely drastic, and make us all want to be grateful for the fact that we can all fill our lungs with as much as with the oxygen.
