For those who don't know, the helium we use for party balloons is mostly the accumulation of Alpha particles in petroleum reserves. When that helium is released it floats into the upper atmosphere and boils off into space. All other methods of helium acquisition are extremely costly and inefficient. This means that in the next couple hundred years more or less, humanity will run out of helium cheap enough to use for piddly things like MRIs and particle accelerators. It will essentially become the most valuable resource on the planet mostly extracted from volcanic gasses.
