    Yes, lawns are wasteful.

    But there’s also water quality and flooding issues associated with using all available land for building.

    Grass and dirt absorb water. Rooftops and concrete don’t. 1-inch of rain on an acre of grass will be absorbed. Replace that grass with impervious cover and you’ve got an extra 27,000 gallons of water, or about 2 swimming pool’s worth of runoff.
