Simultaneously too much and also too little CO2.

Insufficient CO2 for things like food packaging, fizzy drinks, abbatoir use which will lead to shortages and price rises.

Too much CO2 in the atmosphere causing climate change.

I know that there are companies looking at ways of drawing CO2 from the atmosphere/air but there are currently only a couple of very small scale prototypes. Sounds very much like the first production size operation will make a killing.
