Food scarcity and the threat of famine are severe crises. In most historical examples, after a disaster like a massive volcanic eruption, the chain supply is shot down for an undetermined period. The real scary thing is that a volcanic winter can occur in any country, regardless of economic status. At any time.

Watching an old TV documentary, (the effects of the 536 AD Krakatoa eruption) I realized the odds of such an event in the future will be a real threat in the long term. It will happen someday again and that´s inevitable. My worst fear? the associated drought and the effect on the pollination agents.

Mind you, I hate the idea of my great-grand-grandsons (or the ones that come behind) having a hard time. I could at least leave behind some blueprints, land, protocol manuals, and stuff to help them endure the hardships. (Sorry, lads, but I don´t think there will be too much money left. You´ll have to make it with what you got, and the stories/books and digital library I'll leave for you.)
