The earth has a finite amount of helium and one day it will be all gone.
Which is bad because liquid helium is the only thing cold enough to cool the
magnets in MRI machines.

PJ: Where would the helium be going? Is it all trapped in mylar balloons or
something?

Good the the ENTIRE UNIVERSE is 23% helium.
Hopefully by the time we run out we can figure out how to harvest some.
