If oxygen is over from the ground – then
1 :- All the building made from concrete will fall, because oxygen is helpful in keeping it in concrete state.
2 :- Water from all the oceans will flourish because after oxygen it will only be hydrogen.
3 : All of us will loss the function of Eustachian tube. because we will lose 21% wind pressure
4 :- The Earth will be altered, because 45% of the earth is made of oxygen.
Surely GOD has power of all things.
Then which of the bounties of your lord will you deny ?
