I read something about this a month or 2 ago, but don't remember where. Those rechargable CO2 cartridges you used to be able to exchange at Target, Best Buy, etc. -- SodaStream refills. Why is it they're so scarce now?
Is it that CO2 is a by-product of making beer and with bars closed, less beer is selling/being made? Am I remembering this all wrong?

Found it (or something credible on the same subject). And I had it backward -- the cause is less ethanol fuel refining, and the effect is also hitting beer production.
"Most of the ethanol produced in the US is blended into gasoline and used as a fuel. As a result, CO2 supplies is linked to fuel demand and production."
Wait, wut? Mushroom shortages too?
