I know I've said it (to whoever is in the car at the time) every time I pass a lawn with sprinklers going full blast.......
"Our grandchildren are going to want that drinking water one day!!" (probably our children, the way we're wasting water)
Purified drinking water on turf - one of the biggest wastes ever. When recycling those plastic water bottles, also turn off the sprinklers.
Turf grass is amazing, as it will turn green everytime it rains, no drinking water needed.
