Fair enough, but there are a LOT of options we just don't even look into because they're not profitable at current low food prices. It's like mineral resources vs reserves, basically where there's a will there's a way. Agriculture is currently less than 5% of GDP, there's a lot of headroom for putting more effort into it. Nuclear-powered vertical farming anyone?
