So the 2 acre thing - well - itsit's a stake in the ground. If you are using traditional methods...I don't think itsit's actually very far off. I also agree with a previous comment/assumption - where's the food coming for the animals...I think they are assuming this is this a "closed system" - the holy grail of all gardeners - true food independence and begs the question - is there a self-sustaining model available to most people. Ideas like this will absolutely make a difference - where our food is becoming more and more a blind item at markets.
All things can be improved. Vertical gardening techniques certainly cut down on space requirements in theory. Aquaponics...Green houses...Climate...Design plans (Annualized solar), soldier fly larvae for chicken feed (again location dependent) - There's alota lot of information out there.
It's like asking a stranger how much they spend on heat a year...and then gasping at the answer...without asking how big of a house they are heating...where they live...the age of the house...if it's insulated properly...what type of heat to they use or what type of heating system.
This really isn't a simple problem. - especially if you are looking for sustainability and a closed loop system/factor.
It requires alota lot of process and planning.
I think everyone wants to be independent with all things...electric...heat...rent/mortgage...and food...
The feasabilityfeasibility/effort scale - I'm not sure if most people have that much ambition and forsightforesight available to them. They may not realize that such a project - is a commitment to a certain lifestyle - in order to be remotely sustainable. Permaculture...fascinating!
So processes and systems needs to be developed for many climates with goals in mind for both sustainability and abundance. There is a cost to set up such lofty goals, but I think it's a worthwhile problem to solve and once designed - truly designed - hopefully it will be simple enough, attractive enough and modular enough for others to easily follow.
Great post!
