This is going to fail spectacularly if anyone tries to adapt this to a larger scale than what would be required to sustain a small township. Not saying it isn't a great idea, just saying it ain't feasible at this point. Not sure if they've noticed but creating thriving self-replenishing eco-systems is really, really hard and keeping a precise balance that maximizes our food output against competition from the symbiotic flora and fauna, as well as pest species, would be a whole new kind of complicated and labor intensive on a large scale. Upside is it would probably create a lot of unskilled jobs in the agricultural sector as it would make the high volume use of pesticides and herbicides nigh impossible due to the risk of harming the species that you want to keep around, meaning you will need people out there targeting specific problem areas until we can replace them with drones. Unfortunately that means your already inflated grocery bill is gonna grow a lot bigger.\n\nThis is going to look great on paper and in small scale experiments, it's definitely going to have its partisans.
