The church has just been preparing for generations for whatever disaster may come along. It has nothing to with any particular crisis.”
Koppel emphasized the LDS Church’s organizational discipline and self-sufficiency in his book.
“What really impressed me was the layering, which begins at the family level and moves on up to the very stages of the church hierarchy to the point where the church itself has branched industries,” Koppel said of his visit to Utah. “Quite literally, you have an organization that is capable of producing food, processing food and transporting food to the degree that it really amounts to an almost governmental-like organization — except more efficient.”
While Koppel said it would be nearly impossible for Americans in general to duplicate what the church has been establishing for generations, he did say that people could “learn from some of the more basic things that Mormon families do.”
"What distinguishes the Mormons is their extraordinary focus on the integration of self-sufficiency and charity." He adds, "The LDS church has set world-class standards for disaster preparedness and imbued its membership with a sense of individual and group responsibility."

Members of The Church of Jesus Christ of Latter-day Saints are taught principles of self-reliance as a way of life so they are prepared to withstand difficulties and challenges such as natural disasters, illness, job loss and other unplanned events. Self-reliance incorporates education, health, employment, family home production and food storage, family finances and spiritual strength.
The Church provides an Emergency Preparedness and Response Guide to help families and local congregations prepare for emergency situations. This guide helps families and congregations learn how to plan and prepare for emergencies and how to act and respond in each phase of an emergency—before, during and after.
Church members are also encouraged to have a supply of food and water for times of emergency. Latter-day Saints and others can purchase food storage at one of the Church’s 100-plus home storage centers (different than a bishops’ storehouse) in the U.S. and Canada. The Church advises its members to build a supply of food such as wheat, rice and beans that will last a long time. Properly packaged and stored, these items can last 30 years or more.
