This week’s Do One Thing is about water – the water you let run while you are brushing your teeth. Way too many people leave the water running out of the tap as they brush their teeth! In fact, if everyone in the United States shut off the water while they brushed, we could save around 150 billion gallons of water per year. That’s no small amount of water that could be conserved by such a simple flick of the wrist. So turn off that water!
