As a counter argument, lawns are a resilient, walkable surface that’s pleasant to sit or walk on. It’s great for children and pets. I haven’t come across a lawn alternative that is suitable for the load of dogs and children. But I don’t spray, and I do not use a gasoline mower.
I have my lawn bordered with a mix of native and nonnative ornamental plants and trees, forming about 30% of the available land.
