We don't have enough food to survive a natural calamity. A volcanic eruption in Indonesia in 1815 left behind a cloud of ash that blocked much sunlight for months and led to food shortages all over the globe. A similar eruption could happen at any time today. The population of the world was around one billion then; now, it's approaching 7 billion. We've dramatically improved food production, but we haven't improved food storage at a similar pace. World food reserves amount to only a few weeks' worth of normal consumption. If another volcanic eruption of similar magnitude were to occur today -- and it could -- then we could see a global hunger emergency on a scale never before seen nor comprehended.
