One point on top of the poster that I think also matters, especially if you want more people to get involved: aesthetics.

Any regions of the world people actually live have really beautiful natural plants that are often excluded from peoples yards just because it’s not what the builder has massive stockpile of. You can use local plants to make your property look distinctly and beautifully “of a place” and not some e.g generic American burb or “trying to imitate” some other place (palm trees in Seattle, im looking at you)
