America, Britain, Canada, Australia, New Zealand, and South Africa began with economies based primarily on agriculture. Once the agricultural foundation was stable, other industries and commerce could flourish and grow. But even when a nation is considered an industrial, commercial, or technological giant, if it cannot feed its citizens, it will quickly lose its power and status. Thus, a blow to a nation's breadbasket is often crippling and sometimes fatal.
