> Every source I've looked at puts the minimal land area for food production for one human at about two hectares with traditional agriculture, and maybe half that with modern industrial double cropping methods. You yourself said that technology doubled the output with the same input. The whole articles point is that tech enables us to get more from what we have, to support growth. Maybe enough smart Americans will find a way to double it again, so the US can support 660M people with our 166 Hectares. Maybe then we’ll support 1.2B after a new invention! Maybe they’ll discover a way to grow plants with salt water allowing use of the ocean while saving the freshwater. Maybe then they’ll find a way to make hydroponics less material intense, and they’ll build floating farms on the ocean, giving us more “land”. Given enough smart people, there’s so much more room for growth. That’s the point. We’re not at the breaking point yet.
