Water Wonder

We pack water around everywhere we go. We are veritable bota bags of water. We humans are roughly sixty to seventy percent water. Since learning these factoids, people have been fond of comparing our water mass to that of our planet, which is about 70 percent water. It’s a nice correlation, sure, but vanishes when we contemplate drinkable water. Only about two-and-a-half percent of the water adhering to our oblate spheroid is fresh and drinkable. The rest of it is saltier than the glass rim of a Bloody Maria. And there is probably another ocean’s worth of water in the mantle of the planet. It all adds up to something like 326 million trillion gallons that we live above, below, and around. That’s a number with eighteen zeros. When I attempt to parse a number like that I feel like a hamster trying to comprehend a fork.

Let’s go back to the water we can drink for a minute. We Americans take it for granted, yes? Much of the two-and-a-half percent that is fresh water is locked up in the polar ice caps. The arithmetic, then, says we have less than one percent of all the water on earth to hydrate us land creatures, including the plants with whom we share the land. That’s still a lot of water but it’s a useful perspective to have when thinking about human population and the survival of life as we know it. In the United States, the aquifer levels have been depleted by a volume equal to two Lake Eries. And that trend continues unabated. Perhaps all the people with their heads stuck in the sand should look for potable water while they’re down there.

When water shows up where it’s not wanted, it is mind-bogglingly powerful. Just ask Midwest folks or the people living in New Orleans. Last year alone, USA flood damage ran into billions of dollars. We can redirect water or block it behind a levee or a dam, but when containment fails it will go wherever it wants to with no respect for any of us, fitting exactly whatever container it fills, be it a glass, a riverbed, a house, or a city.

Perhaps the most fascinating characteristic of water is its surface tension, defined by Webster as : the attractive force exerted upon the surface molecules of a liquid by the molecules beneath that tends to draw the surface molecules into the bulk of the liquid and makes the liquid assume the shape having the least surface area. It’s why drops are round, why water striders can dance across the surface of a stream, why needles can float, why after a spill beads form on your kitchen counter, and why kids can delight in the magic of soap bubbles floating on the breeze. It also serves to help your eyeballs (cornea) stay moist. How cool is that?

Yep. Aside from being essential to life, water is the universal solvent, the patient carver of rock into spectacular landscapes, the carrier of rich nutrients onto farm land, and the enabler for me to sit here thinking about it. If I sit and think about it for twenty-four hours, I will have exhaled about a cup of water.

I think we have to be better giving back than that.

    I like this one – and of course it must lead to the ponde of how much water that we the human beings of this planet waste.

    Thought provoking post, every molecule of water is recycled. Don’t flow with the flow, be the water and you can change anything!

    Oh really?! Only 2% of water drinkable? I didn’t remember it’s so little, gosh. Well, then I’m really lucky to live in Finland! We take drinkable running water as self-evident!
