Name a more wasteful use of land

Golf course.

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.

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.
