Ask any farmer what they would give to be able to control the weather on their farm, timing the storms to the minute and setting the temperature to within a tenth of a degree Celsius, things that would be trivial (so long as they don't use more power and water than available) in an orbital greenhouse.<br></p></blockquote><div>I think there are vast inefficiencies now in agriculture, especially because of policies regarding farming and land use. In the US, this amounts to farming areas that probably wouldn't be farmed, keeping prices high (under the rubric of stabilization), and exporting surplus (often in a way that disrupts markets elsewhere, especially in Africa). I'm not saying eliminating all this would turn farming into a paragon of efficiency, shaking out all problems. But it would help much and give a clearer idea of the costs farming on Earth versus in space.<br><br></div><div>By the way, kind of tangential, but have you read about sea vegetables? That might actually a better way to get food than land farming -- for those who can stand kelp and seaweed.
