What is the likelihood of a major food crisis? How can we stop it?
gpt
Due to the oil intensive nature of modern agriculture, major food crisis will likely be precipitated by significant disruptions to oil markets and supplies, i.e. trouble with Iran and the Straight of Hormuz. Modern agriculture is increasingly consolidated into the hands of fewer and larger companies. Really the only way to avoid large scale food crisis is to promote decentralization of food production such that a significant portion of food production is shifted into ones own backyard or neighboring small farms. This will mitigate the oil reliance and the risk of putting too many eggs in the mega farm basket. 

TL:DR-Grow a garden.
