New Data Just Revealed Something Horrifying About Our Water Shortage

Rising global populations and a growing reliance on already depleted groundwater are brewing a perfect storm for a major global water supply shortage, the United Nations warned last week.

According to the annual World Water Development Report released Friday, about 20 percent of the world’s groundwater supplies––water that we collect from beneath the Earth’s surface––are “overexploited.” But that problem, the report says, will only get worse by 2050, when the global population is expected to reach more than 9 billion, driving demand for water up by more than half. On a shorter timeline, if meaningful changes to how we manage water resources are not enacted soon, the world could be facing a “40 percent global water deficit” within 15 years––left with only 60 percent of what it actually needs.
