ANSWER ☘️❤️☃️
- 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. The air pressure on the earth would drop 21 per cent and our ears would not get enough time to settle.
