Is a world food shortage coming? Are you prepared to survive world food shortages by having enough staples on hand to last for several weeks?. Hoarding food in the face of shortages is almost always discouraged by governments since this practice drives up prices and accelerates shortages. When times are relatively good however, it’s not a bad idea to stock up on long lasting staples and canned goods. Some of the world’s major religions, such as Mormonism, encourage members to keep several months worth of emergency food supplies on hand. In these uncertain times such a practice of preparing for food shortages might not be a bad idea at all.
