Water Zoom In 1

Not as Wet as It Looks
Photograph by Peter Essick

As the South Nahanni River sweeps through northwestern Canada, it reminds us that fresh water abounds—for those who have access to it. Canada has less than one percent of the world’s population but a tenth of Earth’s surface fresh water. Most people live without such bounty. Though the planet has 333 million cubic miles (1.39 million cubic kilometers) of water, 97.5 percent of it is too salty to use. Of the water that remains, nearly 70 percent is tied up in glaciers and ice sheets, and 30 percent is groundwater, much of it beyond reach in deep aquifers. What’s left for the planet’s 6.2 billion people? Less than .01 percent of Earth’s water.
