Spot on.
Yes.
I live on a lake, no problem for me but good advice. many companies sell water purification devices but simply filtering and boiling works well too.
White rice and most other commercially sold rice is almost devoid of nutrients. Proteins in beans yes.
Maybe, but few people know how to do it right, me being one of them. Here in the suburbs, I'm pretty sure hungry neighbors will steal from my garden whenever they get a chance.
Yes.
Good advice. i bought a good source for that a while ago. Can't remember the name of it but it's a survival guide. Did you know that parts of the Cat Tails that grow in lakes are edible and nutricious?
Yup.
The main thing about rice & beans is the combination of the two. Eaten alone, they provide minimal nutrition but eaten together is much more beneficial. Anything commercially grown is lacking. You can grow your own rice and there are some that don't need a wet paddy.
Living in the burbs.......the best defense is a good offense. SHTF and HOA rules are null & void......get to know your neighbors and get everyone to contribute to their own survival. If they have any stake in it, they'll also help protect it.
IIRC, it's the tuber or rhizome of the cattails that are edible??? And so are carrot tops and other parts of veggies that most people throw away. Kale isn't a big favorite of most people, but those types of greens you're not fond of eating straight up can be dehydrated and ground to a powder to be added to meals and helps boost the nutritional value. A teaspoon or so of the powder mixed in, won't effect the taste, but will give added benefit.
Learn to have and/or make your own condiments and spice mixes. It will help alot of you are stuck with rice & beans to be able to change up the flavor and avoid food fatigue or whatever it's called.
If you have pets or other animals, have plenty for them too (food & water) AND know how to make a healthy homemade version in case you run out of store bought. Keeping the critters happy and they can be your eyes & ears and even security force.
It's a good idea to look back on history to learn how civilization ever survived before Walmart and modern conveniences. Other history is how people survived the Depression and WW2 rationing. Not just here, but in the UK who were worse off than we were
