I suspect that you have never experienced hunger and what effects that might have upon a population, Australia experiences floods and droughts consider the impact upon your country if supply chains to your country were broken. Quoting: SilverPatriot
Next, consider urban areas whatever country whose population has food for one or two weeks tops if food no longer reached these places what would happen.
Look at the predominately-socialist government dependent in the northeast region of the US during Hurricane Sandy and how these unprepared people wailed for food, water and even underwear while the year prior hurricane Irene hit misstate NY hardest there were no screams for someone to care for them.
When conditions permitted, we ventured out and helped our neighbors and understanding snowstorms we were better prepared it makes a difference.
With urban areas the initial problem is greed, gangs that are not equipped to properly access their situation much rioting, and looting would occur as in any urban area.
I think Hurricane Sandy proved that we're not preparing well for disasters. While we've invested more and more money for FEMA, it doesn't seem that they're very good at deployment whatsoever.
Think about it, all they had to do was move water, fuel, food, generators. That's not rocket science. These areas had established supply chains that could have been politely asked to raise amounts immediately and applied political pressure and incentives, for usually private industry is better than any government entity, with the possible exception of the military.
What did they do? Asks for bids. They don't have loads of these things within a radius of the affected region. They needed a supply to move to that area.
Now multiple that times all of the metro regions. It's counter-intuitive that more would result in any ease of supply chains to maintain flow.
Yes, I agree. Much of coping is regionally-based due to positve (can-do-it) attitude and experience with hardship.
Even if gangs were organied enough to loot well, I think the resulting violence would kill them long before they could transition into rural areas with wells. I think we're in agreement that it would burn out, much a fire break is created to burn out a forest fire.
