I used to think lawns were dumb but then I moved to a place where if you don't take care of your yard, it's just overrun with bugs and weeds. Planting too many trees makes things damp and miserable, open areas are key, but that's where stuff grows. Most plants can't survive being mowed, but grass loves it, and the birds can pick out insects when it's low. So now I like lawns, it's the human version of a meadow. And I don't see an alternative, other than growing an extra long beard, converting myself in mud, and becoming a druid
