Yeah, I don't get the "all lawns are pesticided, herbicided, fertilized, water-wasting monocultures kept in check by gas-guzzling mowers" argument. I've never watered my lawn, don't use any chemicals, have an electric mower (and pay for the fully renewable electricity plan), and my lawn is full of clover, dandelions, violets, plantain, and other "weeds." The bees love it.
Do we plan to decrease the amount of space dedicated to lawn? Yes, absolutely - I plan to put in a lot of fruit-bearing bushes, raised gardening space, and a dedicated wildflower/pollinator garden. The decrease in mowing time alone would be worth it, but I would want the food garden either way. Even so, we'll probably always keep a portion of the back yard in lawn for kids to play - the local park is great, but children can't be unsupervised there. If we have outdoor play space at home too, then kids can play outside while I'm weeding the garden, or DH is working in the shed/workshop. And we'll most likely have to keep at least part of the front yard grass to keep the township and neighbors happy. But that doesn't mean it has to be a monoculture hellscape.
