Lack of:
Knowledge
Proper seeds
Fertile soil
Clueless on weather conditions
The grid will be down so they won't be able to watch a YouTube video.
The list is long
Yes.
It takes many years of doing it to learn it well enough to live from your garden.
The number I would tend to agree with is 1 acre per person to eat correctly twice a day until the next harvest.
All of these folks who think it'll just work out will starve or get shot trying to steal food. Period.
It's not that easy growing something like you would have to in this scenario. Americans as a whole don't have the skills the average uneducated 3rd world farmer takes for granted.
But they gots the kewl toYZz
Do the napkin math for a minute.
2 qt jars a day.
7 days a week
52 weeks a year.
That's just veggies.
Meat will disappear sooner than most believe. Even those with beef cattle will have a very difficult time keeping their herd alive and protected unfortunately.
And they'll be 100% grass fed eventually, so that's something to consider as far as hanging weight and butcher times.
And who is set up to butcher a fucking cow?
Yeah, I know it can be done but who really knows how to do it today?
The 1 mil question is this.
Whatcha gonna do with all of that meat without refrigeration/freezers? Worst case here of course.
Canning a couple hundred pounds is very doable. If you know how and have the stuff. We do it now, but those jars will not be preserving veggies now. See the quandry?
BAsically nobody is prepared well for a truly worst case scenario.
Sure hope it doesn't happen.
The true answer would be to NOT let shit get that bad here. Because it's going to stink really,really,really bad for awhile if it does.
