Worldwide Demand for Water Outstrips Supply: Study Groundwater use is unsustainable in many of the world's major agricultural zones
The world's oldest and largest acquifers, according to the study, have supplied civilization with water for agricultural and industrial use for thousands of years, but are now under threat from over-extraction and the underground reservoirs can no longer replenish themselves at a sustainable rate.
“This overuse can lead to decreased groundwater availability for both drinking water and growing food,” says Tom Gleeson, a hydrogeologist at McGill University in Montreal, Quebec, and lead author of the study. Eventually, he adds, it “can lead to dried up streams and ecological impacts”.
According to Reuters, "Gleeson said limits on water extraction, more efficient irrigation and the promotion of different diets, with less or no meat, could make these water resources more sustainable."
