I can't imagine that building facilities and capturing resources to funnel them into underground farms is more efficient than using the sun, rain, and soil that's already there. With modern farming techniques, you can capture more carbon dioxide in the ground than you produce, and you can create habitats for biodiversity that help dealing with the more unstable climate. But that means more effort in food production, and thus more expensive food. Also you can't sell that idea to VCs or billionaires building doomsday bunkers.

No light? What are they expecting to grow, rhubarb and mushrooms?

How about we stop creating so many people? We don't have to eat vat grown slop if we just realize that there is a limited capacity for this planet to provide us with real, nutritious food.
