Hello - I really enjoy your podcast.
I don't know when you might be discussing something related to this but ... I was listening to a Johnny Cash tune the other day and he wanted to get away from this woman and "go where the air ain't been breathed before". Is that possible (that the air hasn't been breathed before)? Especially in light of the thousands of species that have preceded us. Thanks.

I should think just about every atom of our atmosphere has done the rounds many times over.

Not quite all of them. There are some that certainly have not.

I saw a piece of air today and it looked brand newe !

You must have been visiting Eyjafjallajökull, Iceland!!!
Other than the volcanic origin of components in the air, most of the Tritium and Carbon-14 components in the air come from the sun, and are relatively new.

Nope, never been there.
But, it is the coolest name of a mountain that I know...
Did you learn how to pronounce it? I'm sure it is pronounced just like it is spelled [:-\]

Some bits, yes. Most (all?) of the oxygen in the atmosphere was produced because living things exhaled it.

The question was about breathing... not photosynthesis.

What's the difference? Plants have to breathe too ewe know.

Some of the gases in the air we breathe have come from decay of heavy radioactive elements in rocks ...
Other important examples of radiogenic elements are radon and helium, both of which form during the decay of heavier elements in bedrock.

So have never been breathed before.
