When we use water, we often use too much. We waste it. When washing cars, showering, brushing our teeth etc. Because of wastefulness, there are places that don't have the luxury of being able to wash their car well, and can't water their lawns for more than a few minutes a day.

I hope I was able to help. Best of luck.
