Huge helium discovery 'a life-saving find'

Can you actually extract a significant amount of Helium from atmospheric air? I was under the impression that it was far more likely to escape into space because it's so much lighter than the other gasses in our atmosphere.

Losses to space is the reason we have relatively so little but in absolute terms that's still a huge amount. Helium makes up 5 millionths of the atmosphere.

EDIT: Thanks for the correction.

One half-millionth is 2 ppm. Half of one-millionth is 0.5 ppm. Wikipedia says the concentration is 5.2 ppm.
