Global Water Crisis: Too Little, Too Much, Or Lack Of A Plan?
From space, the idea of a global water crisis may seem perplexing: 75 percent of the planet’s surface is blue. But usable fresh water is a tiny fraction of what we see – only 2.5 percent of the water on Earth. And two-thirds of that fresh water is locked away in glaciers, icecaps, and permanent snow. Of the stock of accessible fresh water, 99 percent is in underground aquifers – some are nonrenewable; and in some that are replenishable, ground water is slurped up faster by a growing population than it can be replaced.
But even so, say experts, the problem is perhaps more an issue of recognizing water’s true value, using it efficiently and planning for the lean times, than it is a lack of overall supply.
