Turn off the tap while you brush your teeth.
How to do it
After you wet your toothbrush, turn off the water. Leave it off until you are finished brushing and ready to rinse.
Why it matters
Saving water helps to maintain water supplies at safe levels. Lower water levels can contribute to higher concentrations of human and natural pollutants, which can put our health and the health of the environment at risk. Turning off the tap also saves an enormous amount of energy that's expended in treating the water and delivering it to your home. Leaving the tap running for five minutes uses roughly the same amount of energy as running a 60-watt light bulb for 14 hours. Plus, saving water means saving money - and every little bit helps!
The first toothbrush dates back to 3000 BC. It was a thin twig with a frayed edge that would be rubbed against the teeth.
