Imagine earth ran out of oxygen for 5 seconds. What might happen?

We all know the importance of oxygen, don’t we? Ok, what might happen if the earth ran out of oxygen for 5 seconds. Thinking nothing much would happen? Yes, most of us can hold our breath up to 30 seconds, so 5 seconds without oxygen on earth would not do any harm, you might think. NO. Read on to find out.

Our atmosphere is roughly 21 per cent oxygen. Coming to the point, what would happen without oxygen for 5 seconds?  

• All the concrete buildings around the world would collapse as oxygen acts as a special binding agent for concrete. Without oxygen, concrete is just dust.

• If at this moment, people out exposed to the sun will experience severe sun burns as the ozone layer(which protects us from the harmful UV rays of the sun) would vanish, as the ozone layer is made up of oxygen.

• Our inner ear would explode, as without oxygen, 21 per cent of air pressure would be lost and our ears won’t be able to handle such a drastic drop in air pressure.

• Vehicles on the road(those that run on petrol and diesel) would instantly stop as the combustion process won’t occur. Also, planes flying up there would come back, falling to the earth.

• The blue sky would turn completely dark.

• The earth’s crust would crumble as the earth crust is made up of 45 per cent oxygen.

See how important oxygen is! Best thing to do, plant more and more trees.
