We all know that water is essential to life. But according to the National Geographic Society, while three-quarters of the earth’s surface is covered by water, only 2.5 percent of that water is fresh. The rest is mostly salt water in our oceans. And more than half of our fresh water exists in the form of snow and ice, making barely 1% of it easily accessible.
While the amount of fresh water on the planet has remained fairly stable over time—being constantly recycled by evaporation and rain back into our lakes and rivers—the population has exploded. This means that every year, competition for an adequate supply of clean, fresh water grows more and more intense.
So in addition to all our other environmental concerns, we have a full-blown water crisis on our hands. What can we do about it? Here are three tips from Sandra Postel of National Geographic’s Freshwater Initiative:
