I sold solar systems for a couple years, and one prospect, who bought everything, panels and battery to sustain his electric usage was convinced something catastrophic was coming, and soon. He had a small 3 bedroom ranch, and one bedroom was floor to ceiling, the entire room except the area to swing the door open, with plastic bins of 25 year food. He took me to a 2nd bedroom, and there was one row floor to ceiling 25 year food, and he went on to tell me he had 20,000 rounds of ammo, and he did not think he had nearly enough. He had 8 - 300 gallon plastic bins in his back yard to store water.
He says to me, what have you done to prepare for the coming collapse? I responded, "Nothing! If everything collapses, I am coming to live with you." Now, he snickered at my response, and I said "you think you and your wife alone are going to defend this hoard of food, ammo, weapons, water, whatever if the sh*t hits the fan? How many people besides me have you told of your cache of food and supplies?"
He would be lucky to hold on to it beyond three months. I am sure some band of thugs would overrun him and his wife, leaving them dead in their wake. All that thought, money, energy put into something that gets taken away.
I heard a report months ago that if everything collapsed in the USA, within one year, 90% of Americans would be dead from starvation, murder, exposure, and half a dozen other reasons. 90%, that is a ton of dead folk.
When I saw the movie
The Road one year after it came out, I thought it far fetched. Now, I can actually see it happening. Same can be said for the movie
Soylent Green. Far fetched is becoming reality right now. They want us eating bugs, so why not reprocess humans into food versus burying them in the ground? I can see it happening.
I can also see multiple viruses being intentionally released, each being more virulent than the predecessor, all designed to eliminate the majority of the global population. Right now the globe stands at 8 billion, probably 10 billion by 2050. I can see them taking that number down to 50 million +/- by 2050 by an and all means possible, all in the name of saving the planet. That is not a far fetched idea in this world today.
