Talk about whatever, respecting the rules established by Lemmygrad. Failing to comply with the rules will grant you a few warnings, insisting on breaking them will grant you a beautiful shiny banwall.

You have three options:
You create them from pure energy via fusion of atoms.
Offworld.
Recycling.
For food there's a fourth option:
High tech approach - orbital farms, horizonal farming, farming levels in the city. If you have a city wide planet, energy is no longer a problem. Otherwise you'd not have made it that far.
My problem is the city wide planet. How the hell did you get all that metal. I guess you’d need star wars level tech and space knowledge/capabilities.
You are right to guess that. I think that while fun to speculate, read and write about, this scifi stuf that the person you are replying to is writing about is not particularly relevant to the problems we are facing here and now. We should look to more realistic solutions rather than fantasizing about mining asteroids and building orbital platforms to solve our problems on earth. I mean that stuff is cool, don't get me wrong, and we should also work toward eventually getting there in the long term, but when it comes to issues that are affecting us in the short to medium term we must also have solutions that are realistic in the short to medium term, i.e. that rely on already existing science and technology. It will already be enough of a challenge to organize politically and to mobilize the economy to implement the solutions.
