Toan asked in Environment · 1 decade ago

What if we all breath the sametime, how long can we do that?

-We just inhale O2, and given that O2 is non-renewable

-This is to see how we can have a figures of this.

-I came up with about 140,000 years

Update:

Sorry for the confusion question. I mean "if": if we all breath, if there no source for O2 to be reproduced

    what a stupid question. what difference does it make if we breath at the same time? and don't plants perform photosynthesis? where did u get these figures to calculate 140,000 years? on what basis. by the way we only take a percentage of the oxygen we breath.

    First you don't just inhale oxygen as you surmised. Most of what we inhale and exhale is nitrogen about 78%less the 22% of what we inhale is oxygen. So if everyone inhaled at the same time the world would continue.....
