THE GUARDIAN - 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."
