“Water, water, everywhere,
And all the boards did shrink;
Water, water, everywhere,
Nor any drop to drink.”
Today is World Water Day and while we have been busy developing technology for renewable energy, I have heard relatively little about how we plan to tackle the looming problem of water shortages.
Peter Brabeck-Letmanthe, chairman of food company Nestle, has written that “we will probably run out of water long before we run out of fuel.” He says:
“The 2030 Water Resources Group estimates that global water requirements will grow by over 50% over the next 20 years. Such levels of usage will be 40% greater than what can currently be sustainably supplied.
By 2030 one third of the global population, mainly concentrated in developing countries, will have only half the amount of naturally renewed water available they need.”
In a reminder of both the necessity, and beauty, of Earth’s waterways, Wired has a slideshow of satellite images of some of some of the longest, twistiest and and most interesting rivers in the world.
