A decrease in the production of grain worldwide could lead to a shortage of other food sources because grain is a key ingredient in animal feed, which is used to raise livestock for meat production. If there is not enough grain to feed livestock, there will be a decrease in the availability of meat, dairy, and other animal products. This could in turn lead to higher prices for these items, making them less accessible to consumers and causing a ripple effect throughout the food supply chain. Additionally, grains like corn and wheat are also used in many processed foods, so a shortage of grain could impact the availability and affordability of these products as well.
