Most people don't know where to begin. Many don't live in areas where they can grow much food due to short growing seasons. IMO it needs to start with educating the average person about these things. Perhaps bring back home economics back to the high school curriculum. Perhaps classes offered locally by cities and towns, kind of a grassroots movement. Perhaps farms being able to sell directly to consumers. Perhaps local markets for food instead of big conglomerate grocery chains. Perhaps going back to the cities and towns having the town butcher, bakery, produce market etc. Perhaps towns and cities providing space for community gardens and holding classes in gardening, canning etc. 😇
