I heard we are running out of helium on Earth. How true is this, and is anyone working on a way to find/create more of it?

Helium is produced as a byproduct of natural gas.  During the Cold War, the US subsidized helium production and created a massive stockpile.  Over the past decade, they have been selling it off, which has made helium very cheap...so cheap, it hasn't been profitable to capture it from natural gas wells, so it gets released into the atmosphere instead.

This is the helium we are running out of, the cheap stuff.  As helium becomes more expensive, it will once again become profitable to capture it from gas wells, and the price will stabilize at a higher level.
