National Geographic Magazine April 2010 - "Water our thirsty world" Special Edition (US)

Consider these stark realities:

* A mere 3 percent of Earth's water is fresh — 2 percent is locked up in
snow and ice, while just 1 percent is liquid surface water and ground water,
available for consumption.
* Nearly a billion people have no access to clean water, and 3.3 million
people die from water-related health problems each year.
* Freshwater animal species are disappearing in general four to six times
faster than land or sea animals — in the United States, nearly half the 573
animals on the threatened and endangered list are freshwater species.

National Geographic's April issue not only celebrates the role of water in our
lives and landscapes but also identifies the key challenges affecting global
supplies and examines novel solutions to address water scarcity.

Providing insight into the key freshwater issues facing us today is a team of
renowned National Geographic contributors who offer unique perspectives to such
topics as the spiritual meaning of water; the effect of melting glaciers on
Asia's greatest rivers; how access to a faucet could transform the lives of
millions of African women; the California water crisis; the tense face-off over
water in the Middle East; and a rescue plan for freshwater fish. The roster
includes authors Barbara Kingsolver, Tina Rosenberg, Brook Larmer, Elizabeth
Royte, Don Belt, Joel K. Bourne Jr., Douglas H. Chadwick and Cathy Newman, and
photographers Edward Burtynsky, Joel Sartore, John Stanmeyer, Lynn Johnson,
Jonas Bendiksen and Paolo Pellegrin.

Complementing six feature stories and two essays are shorter pieces that cover
such topics as water and ice in outer space; using the sun's rays to disinfect
water; collecting water from fog in Peru and rainfall off rooftops in Colorado;
new desalination techniques; the rapidly evaporating Aral Sea; pharmaceuticals
in drinking water; a turfgrass that thrives on brackish water; and the world's
largest swimming pool. National Geographic's trademark maps and award-winning
graphics are featured throughout the issue. Also included in the issue is a two
-sided supplement, with a map showing all the river systems in the world plus a
look at how much water it takes to produce common items that we eat and wear.
