We, the people, are running short of potable water.
On a planet that’s covered with more than 70 percent water, only 2.5 percent is the “fresh” variety.
The greatest part of that is tied up in the planet’s ice-caps, glaciers and snowpack. And what’s happening there? Yes, it’s melting into the sea, left to turn salty and unpalatable.
The reduction in snowpack meltwater alone means major hardship on nearly two billion people by 2021, declares NASA’s Tom Painter, a leading expert on the subject. “It’s one of the biggest stories of climate change.”
By 2025—close now—some 40 percent of the world’s population will be living in countries with chronic water scarcity.
