Our Drinkable Water Supply Is Vanishing

Albert Szent-Gyorgyi, the Hungarian biochemist and Nobel Prize winner for medicine once said, "Water is life's matter and matrix, mother and medium. There is no life without water."

We depend on water for survival. It circulates through our bodies and the land, replenishing nutrients and carrying away waste. It is passed down like stories over generations -- from ice-capped mountains to rivers to oceans.

Historically water has been a facet of ritual, a place of gathering and the backbone of community.

But times have changed. "In an age when man has forgotten his origins and is blind even to his most essential needs for survival, water has become the victim of his indifference," Rachel Carson wrote.

As a result, today, 35 years since the passage of the Clean Water Act, we find ourselves are teetering on the edge of a global crisis that is being exacerbated by climate change, which is shrinking glaciers and raising sea levels.

We are faced with thoughtless development that paves flood plains and destroys wetlands; dams that displace native people and scar watersheds; unchecked industrial growth that pollutes water sources; and rising rates of consumption that nature can't match. Increasingly, we are also threatened by the wave of privatization that is sweeping across the world, turning water from a precious public resource into a commodity for economic gain.

The problems extend from the global north to the south and are as pervasive as water itself. Equally encompassing are the politics of water. Discussions about our water crisis include issues like poverty, trade, community and privatization. In talking about water, we must also talk about indigenous rights, environmental justice, education, corporate accountability, and democracy. In this mix of terms are not only the causes of our crisis but also the solutions.

What's gone wrong?

As our world heats up, as pollution increases, as population grows and as our globe's resources of fresh water are tapped, we are faced with an environmental and humanitarian problem of mammoth proportions.

Demand for water is doubling every 20 years, outpacing population growth twice as fast. Currently 1.3 billion people don't have access to clean water and 2.5 billion lack proper sewage and sanitation. In less than 20 years, it is estimated that demand for fresh water will exceed the world's supply by over 50 percent.

The biggest drain on our water sources is agriculture, which accounts for 70 percent of the water used worldwide -- much of which is subsidized in the industrial world, providing little incentive for agribusiness to use conservation measures or less water-intensive crops.

This number is also likely to increase as we struggle to feed a growing world. Population is expected to rise from 6 billion to 8 billion by 2050.

Water scarcity is not just an issue of the developing world. "Twenty-one percent of irrigation in the United States is achieved by pumping groundwater at rates that exceed the water's ability to recharge," wrote water experts Tony Clarke of the Polaris Institute and Maude Barlow of the Council of Canadians in their landmark water book Blue Gold: The Fight to Stop the Corporate Theft of the World's Water.

The Ogallala aquifer -- the largest in the North America and a major source for agriculture stretching from Texas to South Dakota -- is currently being pumped at a rate 14 times greater than it can be replenished, they wrote. And, across the country, "California's Department of Water Resources predicts that, by 2020, if more supplies are not found, the state will face a shortfall of fresh water nearly as great as the amount that all of its cities and towns together are consuming today," add Clarke and Barlow.

Demand is outstripping supply from the rainy Seattle area to desert cities like Tucson and Albuquerque. And from Midwest farming regions to East Coast cities.
