Take shorter showers. Yes, everyone wants to look (and smell) his/her best for that special someone or secret crush, but how many rinses and repeats do you really need? A dripping faucet can waste 3,000 gallons a year, about the same amount you can save by halving your daily shower time.[1] That's no drop in the bucket!
It can seem like water is cheap and abundant, but access to clean water is an issue for billions of people around the world. Increasing demand for water also affects rivers and lakes (and what lives there) by reducing levels, changing water flow with dams and reservoirs, and introducing chemicals and waste products.
