Overpopulation or a sort of brain drain of the population so it cannot figure out how to co-exist. This seems to be a problem. I see the 'Look at me I have a big gun' problem as very touchy... too many egos in the room where new rules are hypothetically being written for whatever is supposed to happen next. I am not even sure what we are preparing for... but there is a sense of the need for preparedness isn't there? Clean water sources... look at the way people behave on black friday.. now imagine them when the food runs out. Self sufficiency... Can you run your own power? Do you have resources and can you defend those resources if you do have them? Fear Porn. Clowns with knives...a clown with a bad toupee who has the spotlight of the free world... oi vey! What are the problems? Tangibly, if you could pick a top 5 or even 3 calamities we are afraid of or see looming on the horizon. A wonderful topic, JJ, I hope you don't mind that I am dredging things up from pages one and two!
