Indeed it wont happen. World can wait for "wheat supplies to recover" and parallel limit himself of some goods or food. What is food crisis - time when there is nothing to eat. So far I dont see that we dont have real problem with food supplies all around the world. Like the world faced travelling problem due to covid and was patiently waiting for it to over, the same will be with wheat supplies. Wait 1-2 years and everything will be back to normal. The world wont starve to death without having few years same wheat amount as usually.
