From Earth Month Challenge: 30 Easy Actions:  

Today’s action is easy: turn off the tap when brushing your teeth. Fellow green-conscious types probably already do this. Folks who brush their teeth twice a day can save up to eight gallons of water this way.

Handle the challenge the way you might if you were camping. Grab your cup full of bottled or boiled water, and use that to rinse after brushing. Task accomplished – without wasting treated water down the drain unnecessarily.

Try it, folks. We can make a difference.

Stay tuned for more eco-friendly actions throughout April – or go to Treehugger yourself!
