Today the last war started.
Today began the slow, downward spiral that at once brings oblivion and birth. Like the phoenix immolating itself, a fire has been lit that will consume all only to bring life anew. Perhaps, though, a life without us - that is always the risk.
Like all things most dangerous, it has started barely noticed, and the flame that is given time to build, a gentle gust of wind to build its strength. A flame can be too easily snuffed out - too strong a wind will whip the flame away before it can become independent, so can it be smothered in fuel. So, a few notice it, and either ignore it, or cannot report it... or are the arsonists who lit it.
Anger is a strange thing; it can give us the strength to keep going, yet will easily rip us apart. When applied by nations, only desolation results. Nationalistic pride leads neighbours to aggression - preemtively "assuring their own safety", yet pulling the house down around their own heads. When one attacks, there is little need to whip the people into a beserk frenzy.
I do not know how long it will take for the few flames to build to a firestorm, all that I know is that, for all their leaders bluster, millions of civilians will die - for little cause.
So, I continue my progress at building a farm, learn all the things required to become self-sufficient. A few more trees arrive, some with nitrogen fixing bacteria - useful if you live somewhere where the soils need developing. More food trees, some spice trees; never denigrate a spice tree - the taste of something beyond the bland can have a good effect on morale.
A good variety of food, spices, and essentials (such as tobacco, coffee, even pepper) could be traded if one is of that mind. Albeit most people would have plenty, even for the medium term, or would be able to steal while shops were still full... but consumables get consumed.
