I would like to see a return to more local produce. It tends to have more flavour, but shorter shelf life. We had raspberries at home which were delicious, but you had to eat them within 2 days of being picked. The ones I purchase come from California or Mexico, and last quite long in the fridge, but don't have that delicious burst of taste!
There is a movement for the 100 mile diet, but it does indeed pose challenges (it would be impossible here since we are so far north), but many try to stay true to in in Vancouver and southern BC. It does take dedication , extra work to put food into storage, and knowledge of food storage. Most younger people have never tinned fruit, stored potatoes and apples in root cellars or smoked and dried fish or meats.
Knowledge and farming technology have improved, as have the vast variety of foods we eat. Climate change can bring some benefits to northern areas ability to grow foods not previously available.
I saw the long lineups of trucks on highways on the news, and fear you may have some fresh food shortages in January while gov't works out the supply chain for safety.
