I’ve been told there is a shortage of helium and it’s a non-renewable resource. If this is accurate, why are we still using it like it is never running out and does the helium from the balloons go back into the air to be used again?
Helium, in balloons or not, is lighter than air. Sufficiently so that it will float to the top of the atmosphere, where it gets bombarded with solar radiation and blasted off into space never to be seen again.
