Earlier quoted context omitted.
The US or Canada or Australia will be more than able to cover the Russian share by switching out crops if Wheat is more profitable given any shortages.
Especially since the US wastes so much agricultural land on maize that they force onto drivers as mandatory ethanol. (While keeping cheaper ethanol from Brazil out of the country with tariffs and regulation.) If push came to shove, they could drop this silly policy, and alleviate supply shortages.
Is that because of some clean energy policy?
