i just found this
video. i like that this lady combines different "projects", stacking functions (sharing food, education, composting, recycling, community-building, seed-swap ....).
it will not generate income, but if people will want to do this as a social-project or hobby or just to get rid of their surplusses, that s fine.
now imagine a group of people doing that with a food forest in a location that has some traffic of visitors...
