There’s something about water that attracts and fascinates us. No wonder: it’s the most abundant substance on Earth and, along with air, the primary ingredient for supporting life as we know it. To begin with, ocean plankton – tiny life forms that drift or float in the salty waters of the ocean – provide more than half of our planet’s oxygen. Of all the water on Earth, 96 percent of it is salty. Although water covers more than 70 percent of Earth’s surface; 95 percent of those waters have yet to be explored. From one million miles away our planet looks like a small blue ball; from one hundred million miles it’s a tiny, pale blue dot. The science fiction writer, Arthur C. Clarke, once commented how inappropriate it is to call this planet Earth when it is quite clearly Ocean.
That tiny blue ball is a powerful reminder that we live on a watery planet. Without water, life would be impossible on earth, and that seems to be the case all over the universe. So, it’s reasonable for NASA to use a ”follow the water” strategy to describe our search for other life in the universe. While it may not be the only ingredient for life, it certainly makes a great one since there is a lot of it, it’s liquid over a broad temperature range, it floats when solid, allowing for ice-covered lakes and moons, and it’s what is used here on Earth for life to flourish.
Whether searching the universe or traveling around here on earth, humans have always tried to be near water. It’s estimated that 80 percent of the world’s population lives within sixty miles of the coastline of an ocean, lake, or river. Over half a billion people owe their livelihoods directly to water, and two-thirds of the global economy is derived from activities that involve water in some form. Approximately a billion people worldwide rely primarily on water-based sources for protein. It’s very possible that increased consumption of fish and shellfish played an important role in the development of the human brain. We use water for drinking, cleansing, working, and traveling. Each person in the United States uses eighty to one hundred gallons of water every day for our “basic needs.” In 2010 the United Nations declared that safe and clean drinking water is a human right essential to the full enjoyment of life.
When we’re born, our bodies are approximately 78 percent water. As we age, that number drops to below 60 percent – but the brain continues to be made of 80 percent water. In its mineral concentration, the water in our cells is similar to that found in the sea. Science writer Loren Enseley once described human beings as “a way that water has of going about, beyond the reach of rivers.”
We arc inspired by water – hearing it, playing in it, walking next to it, painting it, surfing, swimming in it, writing about it, photographing it, and creating lasting memories along its edge. Indeed, throughout history, you see our deep connection to water described in art, literature, and poetry. “In the water I am beautiful,” the writer Kurt Vonnegut declared. Water can give us energy, whether its electricity created by waterpower, the energizing effect of cold water splashed on the face, or the mental refreshment that comes from the gentle, rhythmic sensation of hearing waves on the shore. Bathing quietly in warn water has been used for thousands of years to restore the body as well as the mind. Water drives many of our decisions – from the seafood we eat, to where we live and the sports we enjoy. Water is something that humanity has treasured since the beginning of history, and it means something different to everyone. We know instinctively that being by water makes us healthier, happier, reduces stress, and brings us peace. When will you next have an encounter with a body of water? It will probably be sooner than you think.
