[单项选择]People kill each other over diamonds; countries go to war over oil. But the world’s most expensive commodities are worth nothing in the absence of water. Fresh water is essential for life, with no substitute. Although mostly unpriced, it is the most valuable stuff in the world.
Nature has decided that the supply of water is fixed. Meanwhile demand rises as the world’s population increases and enriches itself Homes, factories and offices are sucking up ever more. But it is the planet’s growing need for food that matters most. Farming accounts for 70% of withdrawals.
Few of the world’s great rivers that run through grain-growing areas now reach the sea all the year round or, if they do, they do so as a trickle. Less obvious, though even more serious, are the withdrawals from underground, which are hidden from sight but big enough to produce changes in the Earth’s gravitational field that can be monitored by NASA’s satellites in space. Water tables are now falling in many parts
