Helium shortage

In the future, you will see fewer and fewer helium filled balloons like this. (There was even a question of whether Macy's Thanksgiving Parade balloons would be OK...they are, it seems).

Reason is-- as I heard on BBC--is that there is only ONE source of helium in the world, and that is down in Texas or Arkansas or somewhere. It just flows out of the ground. Some day the supply will be gone...
