I would create a worldwide movement to celebrate one day called "A Day Without Water." People would be instructed to not use any water for the day, other than the daily amount needed to survive per body weight. This would include, no washing the lawn, no showering, no brushing teeth, no flushing toilets, no washing hands under the faucet, no doing dishes, etc. This day would just remind people just how much water is being used. The day would a challenge to those who take water for granted and will be forced to think about how other's don't have the same opportunities as they do when they reach to wash the dirt of their hands.
