PROTECTING WATER May 27, 2013

It just seems to me the most obvious and imperative thing to do. We should protect our water supplies and we should not compromise them. Coal stem gas mining is an obvious danger.

Our strategic vision should be global and humanitarian. The broad issues that human beings must contend make issues such as terrrorism trivial.

Fiona Harvey in The Guardian reports:

The majority of the 9 billion people on Earth will live with severe pressure on fresh water within the space of two generations as climate change, pollution and over-use of resources take their toll, 500 scientists have warned.

The world’s water systems would soon reach a tipping point that “could trigger irreversible change with potentially catastrophic consequences”, more than 500 water experts warned on Friday as they called on governments to start conserving the vital resource. They said it was wrong to see fresh water as an endlessly renewable resource because, in many cases, people are pumping out water from underground sources at such a rate that it will not be restored within several lifetimes.

“These are self-inflicted wounds,” said Charles Vörösmarty, a professor at the Cooperative Remote Sensing Science and Technology Centre. “We have discovered tipping points in the system. Already, there are 1 billion people relying on ground water supplies that are simply not there as renewable water supplies.”

A majority of the population – about 4.5 billion people globally – already live within 50km of an “impaired” water resource – one that is running dry, or polluted. If these trends continue, millions more will see the water on which they depend running out or so filthy that it no longer supports life.

The threats are numerous. Climate change is likely to cause an increase in the frequency and severity of droughts, floods, heatwaves and storms. The run-off from agricultural fertilisers containing nitrogen has already created more than 200 large “dead zones” in seas, near to rivermouths, where fish can no longer live. Cheap technology to pump water from underground and rivers, and few restrictions on its use, has led to the over-use of scarce resources for irrigation or industrial purposes, with much of the water wasted because of poor techniques. And a rapidly rising population has increased demand beyond the capability of some water resources.

So, “Water Changes Everything”:

Corporations have strategies. The planet, the ecosystem and the human population don’t.
