I feel like with the advance of renewable energy sources and the lowering prices on things like solar panels, it might become quite plausible for places like Barrow to start growing their food with these methods, utilising zero fossil fuels (or close to zero.) I've seen videos of people with pretty sprawling underground "bunkers" set up for growing fruits and vegetables. They require tons of energy, of course, but if done on a governmental scale, I'm sure it can be pulled off. Both to provide more varied food options and to achieve self-sustenance as well as give an option for a worst case scenario where deliveries are impossible.
