Grab a seed, make a clay and soil mixture, insert the seed into a small compressed ball of said concoction; theeeen, throw it over fences, garages, leave it anywhere and everywhere in your city.
The clay will absorb water from sprinklers and rain (if that happens where you live) and vwolah, the seed will be grow into a big beautiful tree or at least sprout. Pretty much it’s what the kids are into these days, and I for one am impressed and will try it with avocado seeds. As an avocado aficionado I do believe there could always be more avocados in the world!!! I’m going to do my bit to help!
