I think I read someone invented a carbon scrubber thing that pulls carbon out of the air and creates oxygen, so I guess it might be possible to convert all that CO2 one day
you'd think nature would already have a way to do this for us

Was this in response to my comment? I figure that if ~99.8% of the oxygen atoms in dry atmospheric air are in the form of O2, the amount taken up as carbon dioxide is pretty much completely insignificant to us having a high enough proportion of O2 to breathe at this time and in the near future. If O2 levels were to go down to say 15% and those oxygen atoms all became carbon dioxide, that would mean ~150x higher levels of CO2 than today (~6%.)

I guess when you burn fossil fuels you also get some oxygen going to water which is not registered in those dry atmosphere stats, and I was reading somewhere just now that below about 19.5% O2 is less than ideal for humans. Still though, you'd need much bigger changes than we have seen so far from the industrial era to make even that kind of dent.

A response to all and your comment... Oxygen is an element. It exists as oxygen no matter what it is bonded too. Oxygen that goes from being bound up as O2 to being bound up as CO2 is still oxygen. I read the thread title and immediately thought that very little oxygen is being transmuted into other elements, so the amount is effectively conserved and static. But the responses seem to be answering a different question which is related to the health problems alluded to in the first post. That should have been my clue.
I guess the question is how much breathable O2 do we have left?

According to the current model of the universe, aren't all the oxygen molecules that exist constant? Did I miss something?
EDIT: OK DieCommie and I are thinking the same. I thought I was having an ardtard moment or something.

Nuclear reactions can change them. There used to be no oxygen in the universe. But those reactions are hard to come by outside of a star, so effectively the amount of oxygen is constant (as long as you are not in a star).
See these two pages for nuclear reactions that can make or destroy oxygen in a star.

I don't know how much oxygen there is left.
All I know is that I stocked up in case of a zombie apocalypse.

I don't know about that, even though it sounds edgy
WWF claims Amazon produces 20% of the worlds Oxygen, if plankton creates 50% then that doesn't leave a massive amount for the Russian forests, taking into account the large forests in North America, Africa, etc.
They're mostly relatively sparse as far as biodensity goes afaik.

perhaps a more important question is at what % is their not enough O2 to create the ozone layer and all that good stuff anymore

It gets consumed in reactions with other elements. Oxygen is too reactive to normally exist in its elemental state without some process to resupply it. That process is photosynthesis.

The ocean is acidifying due to CO2. This affects pyhtoplankton levels.

But the oxygen doesn't go away does it? I mean the O atoms still exist, they just get locked up in forms that we aren't able to use.

Yes. It does not get "consumed".

Don't believe that garbage. Point 1. there are more trees now than there were 100 years ago. 2. marine plants, including algae produce between 70-80% of the worlds oxygen. Nuff said I think.

Bio-diversity is over rated. Northern Canada has the most bio-productive forests in the world. Diversity is to be respected but productivity is hard to argue with at best.Quote:

Yeah OP seemed to stay on the computer for longer than feasible with that much in edibles.
