Bad news, fellow Earthlings, a new NASA study reports that
satellites show that the world is running out of water. I've read various
articles on the subject and hope that this study will serve as a call to
action.
One key takeaway from the report is the reaction from
conservationist Alexandra Richey who says "Water must be at the center of
all policy." (RT)
From Genesis Nanotechnology:
The world’s largest underground
aquifers – a source of fresh water for hundreds of millions of people — are
being depleted at alarming rates, according to new NASA satellite data that
provides the most detailed picture yet of vital water reserves hidden under the
Earth’s surface.
Twenty-one of
the world’s 37 largest aquifers — in locations from India and China to the
United States and France — have passed their sustainability tipping points,
meaning more water was removed than replaced during the decade-long study
period, researchers announced Tuesday.
Thirteen aquifers declined at rates that put them into the most troubled category. The researchers said this indicated a long-term problem that’s likely to worsen as reliance on aquifers grows. -via: Genesis Nanotechnology: http://genesisnanotech.com/2015/06/nasa-data-suggests-world-running-water/#.VYWNKFVViko

RT also has coverage
of the NASA study:
A joint study conducted by
scientists from NASA and the University of California has revealed that the
world’s water reserve levels have become dangerously low.
The main
reason is humanity’s constantly growing demand for water.
The
researchers have concluded that “significant segments of Earth’s population
are consuming groundwater quickly without knowing when it might run out.”
The scientists
used NASA’s twin Gravity Recovery and Climate Experiment (GRACE) satellites
between 2003 and 2013 to take precise measurements of the world’s groundwater
reservoirs, yielding the most detailed view of the planet’s underground water
reserves to date. The GRACE satellites detected changes in the Earth’s gravitational
pull, as large volumes of water under the ground create stronger gravitation.
The study has
showed that about one third of Earth’s largest groundwater basins – 13 of the
planet’s 37 – are being rapidly depleted while receiving little to no recharge.
