Whoa whoa whoa folks. Try to stay on-topic. Read the scenario and try to imagine the death rates from dehydration and starvation.
There's clear parameters, so let's do a discussion on that, and not turn it into a prepping topic, for we have lots of those threads.
I'm hoping we can do a critical analysis and make reasonable challenges to assertions and consider facts, not opinion based upon human metabolic needs.
Otherwise, it'll become a free-for-all.
I'm waiting on others ideas before providing my own estimates.
Why is this important? Most people think in terms of hordes of refugees and bugging out folks. It's my belief that most would die from lack of skills, physical and mental health limitations, seasonal challenges, low blood sugar, lack of staminia.
While we think we're strong, we also know we've been very domesticated and most people are docile. Sure there's a large number of former criminals, drug addicts, and sociopaths, but I believe that many would die in migrations, just as many died in history in migrations.
The ones who stayed probably couldn't source things like enough fuel to boil water, stay warm, cook, etc. Same thing with food from Nov-June based upon local species populations, adequate protein, carbs, fats, vitamins, and minerals.
Think in these terms.
