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.

Name a more wasteful use of land

Golf course.

These grass lawns always looks awful. 1 color, 0 personality and no variety.

More plants are always better. Also even better plant a fucking tree.

Decorative open space is important for making cities livable but uh… lawns ain’t it.

I was about to say golf courses, but then I realized that people actually use golf courses to play golf, which is more then the average lawn is used for.
