Where do you get helium from?

Could you elaborate on the sources of helium acquisition? Given its unique properties and applications across various industries, helium supply is often a matter of interest. Could you highlight the primary sources of helium, whether it's through natural gas extraction, air separation plants, or any other specialized methods? Additionally, are there any geographical regions that are more abundant in helium sources, and how does this affect global helium supply and pricing? Clarifying these aspects would greatly enhance our understanding of helium procurement.
