Freshwater is our planet's most precious resource, and also the
least conserved. Freshwater makes up only 3 percent of the total
water on the planet, and yet the majority (1.9 percent) is held in
a frozen state in glaciers, icebergs, and polar ice fields. This
leaves approximately one-half of 1 percent of the total volume of
water on the planet as freshwater available in liquid form. This
book traces the complex history of the steady growth of humankind's
water consumption, which today reaches some 9.7 quadrillion gallons
per year. Along with a larger population has come the need for more
drinking water, larger farms requiring extensive irrigation, and
more freshwater to support business and industry. At the same time,
such developments have led to increased water pollution. Three
detailed case studies are included. The first looks at massive
water systems in locations such as New York City and the efforts
required to protect and transport such resources. The second shows
how growth has affected freshwater quality in the ecologically
unique and geographically isolated Lake Baikal region of eastern
Russia. The third examines the success story of the privatized
freshwater system in Chile and consider how that country's water
sources are threatened by climate change.
