Oil poured down storm drains often flows directly into water supplies. Turn off the water when you brush your teeth. Pick up pet waste. Bury it or put it in the garbage. It makes life on Earth possible and is used by every living thing, but most water is unavailable to us.
Water is an abundant resource that is also rare.
It sloshes in salty oceans, is frozen in polar ice, is trapped in the soil, is held too far underground or is polluted. Water is as old as the Earth. The water we use today has traveled through the water cycle for billions of years. We use water to grow food, produce electricity and transport goods. We drink it, bathe in it, play in it and depend on it to always be around.
