Can greenhouses entirely replace agriculture?
In the event that we really screw ourselves with environmental failure, can we mass produce our fruits and veggies in an artificial environment?
So instead of prairies and farms, we'll have endless landscapes of gleaming glass and steel in which we use advanced robotics and hydroponics to produce our foods.
Is this doable? It'll be our ticket to rapid colonization and development of other worlds if it is!
My title is incorrect. I meant replace "traditional" agriculture.
Another note, this kinda thing would financed by a sort of new government initiative, one of emergency in direct relation to the global situation, when crops stop growing and so forth.
So I guess a better question would be, can the economy take this kind change? That of course is a whole other question...
In theory - yes. I can think of few less likely scenarios. The breakdown of society that would accompany such a devastation of the natural productivity of the earth would preclude the possibility of safely and securely producing food solely from large, vulnerable, greenhouses.
