2 weeks of food
Jars of peanut butter. Stuff is so calorie dense, ready to eat, protein, sturdy plastic containers for shoving into backpacks. A couple jars will do for only a few weeks.
Downside is that it doesn't last quite as long as dried beans and rice. But beans and rice take up alot of space and I don't eat enough to rotate out years supply worth in time.
Plenty of humans to eat as well. Don't discount what the wild animals around you can provide.
What can I say, the implausible seems more possible the longer the status quo persists.
The justifications of keeping things as is gets so ridiculous that in comparison even the most ultragigagigantic dreams seem reasonable.
