If we are talking about growing plants some folks use greenhouses, grow plants on the roof, use hydroponics and other methods that are being used today to grow food in cities where little if any space is used for gardens. Then of course there is the raising of animals for food, which could be done. Someone mentioned Soylent Green of course. This reminds me of Mega City One from Judge Dredd where the population is packed into these blocks and there is little space to grow food and the land outside the city is not usable. Of course we are talking about a world where magic is used and could be used to create food or take food from other worlds. I suspect that the world of Ravnica could be a trading hub and there could be portals to other worlds like in Stargate. However it is, assume that there is a solution that has been developed for this problem and it will be interesting to see what that workable solution is rather than assume the whole idea is stupid because you can't imagine a solution that satisfies you. This is like throwing the baby out with the bathwater thinking.</blockquote>
