Modern Kids Stories affected by the virus of civilization

Today I was at the local school to read stories to kids and to my surprise, they came with a book about a funny paleo child that used to paint animals in caves and everytime he did that, bisons, deers, all kind of birds, mammuth etc... would gather around him.
Unfortunately though, people from his tribe blinded with greed, took advantage of the situation and killed most of the animals so that they ended up without food and instead of hunting/gathering, humans became agriculturists..

I did not like the ending - that came totally unexpected as I did not know the book - but I quickly turned its message to a more proactive one - that is respect and care for the natural resources around.

And it came just about right because we went to pick some cherimoyas right after.

This event stimulated some thoughts into my head, like

• Yet again  we can see that "total faith in civilization"is  lurking at every corner and it is scary the way and the means it uses to propagate itself like a deadly virus..

• It was sad and alarming at the same time to notice that the writers of this story pointed to this passage in history of man as if it was a "blessing". And it is ever present  in civilization..

• Faith in agriculture is same to faith in technology.

We are moving towards an era where the food will be made of plastic and 3d printed foods  and the premises are just the same as for the gmo`s - saving world from hunger.
This time we will get supersick and die instead of bugs and billion people will be exterminated within maybe 1st generation?

Question no1: A sustainable food strategy?

Somebody asked me about to show a sustainable food strategy for these modern times:

Hello Aura
If not hunting/ gathering, and it sounds like you don't support agriculture. Do you have a third option?

My answer:

Switching to a new dietary paradigm that is adopting "unusual" wild, resistant plants instead of domesticated varieties.

An example?

1. Fresh fruits (any kind of wild or heritage variety) and Starchy tubers (or any other semi_wild root) as a primary source of energy, fiber and vitamins
2. Insects/ophidians/amphibians,/gastropodas/fish/eggs/nuts & seeds as a quickly accessible source of protein, 
3. Wild shoots/mushrooms/algae/leaves (the so called "wild edibles" ; no need more than an handful and they grow just about everywhere in abandoned fields or by the side of the roads), as a source of fresh minerals.

This would be a mixture between the hunter/gatherer and the agricultural lifestyle.

Not to mention the tremendous health/economical/global benefit of this simple but nutritious diet.
