Fun fact - basically the only source of helium is radionuclear decay in i want to say granite, and it's a completely non-renewable resource on human time scales.
And we pump it into balloons lol
We have heaps of recoverable helium, enough for hundreds of years.
The real issue will be economically recovering helium when huge gas fields are no longer a thing.
