WATER: How much do you use?

How much water do you use? Image: “Blue question mark,” wikimedia commons.

Only 1% of water on Earth is drinkable (actually, it’s 2.5% but only 1% is readily accessible). The rest of the water on the planet rests in the sea, but it is salty and therefore requires desalination to use for drinking or agriculture.

Ever since the most ancient times, humans have invented ways to find, distribute, use, and power with water. From the Roman Aqueducts and the New River of England that brought fresh water to the growing cities of Rome and London, respectively, to the water use agreements of the Colorado River of the USA and Snowy Mountains Hydroelectric of Australia, the story of civilization is the story of water.

With populations growing and climate changing, water will become more scarce and more important for uses for drinking, agriculture, industry, and energy. While macro systems that deliver water to our taps are large in scale, each of us can do something to protect and conserve water.
