Humanity's unquenchable thirst for fresh water is driving up sea levels even faster than melting glaciers, according to new research. The massive impact of the global population's growing need for water on rising sea levels is revealed in a comprehensive assessment of all the ways in which people use water.
Trillions of tonnes of water have been pumped up from deep underground reservoirs in every part of the world and then channelled into fields and pipes to keep communities fed and watered. The water then flows into the oceans, but far more quickly than the ancient aquifers are replenished by rains. The global tide would be rising even more quickly but for the fact that man-made reservoirs have, until now, held back the flow by storing huge amounts of water on land.http://www.guardian.co.uk/environment/2012/may/20/world-aquifers-rising-sea-levels?intcmp=122
