The edible yard
Really, all what's left of the lawn does is cost me time, and, if I'm not careful, money. Grass is tough, so although I've tried to kill the lawn with neglect, that's not working (and looks ugly). So the only solution is to kill the lawn by replanting with life forms that serve a useful purpose: That are edible, like vegetables or berries or fruit trees, or which attract pollinators and improve the soil, like clover. And, interestingly, formerly petroleum-driven lawn care businesses are changing their business models to answer this demand.
Again, again, again: Many small drops make a tide. Less petroleum (rent) used by the lawn care business. No corporate seed + spray (rent) regimen from the lawn care people (at least so far; it only took the corporations about a decade to subvert "organic"). Less hideous chemicals in the watershed. More niches for worms, insects, birds. And best of all, if neighbors compete, as they will do, it's going to be on the basis of living plants and not the flatness and color of an inedible, indeed poisonous mini-monoculture like the lawn.
So if you want to increase the "curb appeal" of your house, get started today! Because in ten, five, or two years, a beautiful garden is going to be a status symbol.
