What would happen if we lost oxygen for 5 seconds?
The ozone layer is made of oxygen. If the world lost its oxygen for five seconds, the earth would be an extremely dangerous place to live in. Due to the severe sunburn, our inner ear would explode. In between all this, the earth’s crust, which is made up of 45 per cent oxygen, would completely crumble.
