I’d guess that most industrial users of helium don’t consume it and could theoretically recover it from whatever process it’s involved in rather than just releasing it.
EDIT: Hard drives being an exception, as apparently some ship helium-filled; there, it’s actually being consumed during the manufacture.
EDIT2: I’d also point out that in the long run, we probably do have to be more conservative with our helium supply. We get it from pockets in the earth. It’s actually not all that common; it just happens, though, that we go to a lot of effort to extract natural gas, and that happens to sometimes also come up with helium, so we get that supply. But because it’s not reactive, it doesn’t bond to anything — it stays in gas form. When we let it go, it heads to near the top of our atmosphere and eventually gets lost to solar wind. Many users who today just release it — because why not, as the natural gas people will be providing more, and it’s cheaper that way — probably will need to capture what they’re using if we want helium to continue to be available.
The problem is that helium is notoriously hard to contain. It’s transported and stored super-cooled, but it still gases off, and to release pressure they just have to release it into the atmosphere. It effectively has a shelf life and so it has to be constantly replenished.

What is it that keeps the underground pockets of helium in place, anyway? Just craptons of stone?
