Growing crops is only a small part of food cost 3x production costs are meaningless. Why do you think small time farmers have all gone out of business, you need enormous economies of scale to make a profit. Or get in to one of those direct field to consumer schemes.
Most of the money is tacked on later down in the production line. 1 tonne of wheat is $250 a loaf of bread is $2.5 you can make ~750000 loafs of bread out of that tonne of wheat So even if that tonne of wheat suddenly costs $1000 to produce...
The fertilizer thing shouldn't be that much of a problem either if it's used wisely. Ban the use of chemical fertilizers for domestic use and that demand is more than halved.
Economies are tanking, middle class is seeing their savings wiped out trough hyper inflation and investments wiped out on the markets as a cabal of fuckers is buying their houses from under them as they weren't allowed to collect rent for 2 years.
I'm pretty certain Russia was forced in to doing this and this war will be expanding.
I take it you have seen the explosions in Luhansk.
Same thing happened in 1989 weeks of BS about talking to Sadam and trying to do the diplomatic thing in the media while an official date for the invasion was already set months in advance.
I hope for your sake you are in the south and no where near Syria
