A global crisis is unfolding as countries, including the U.S., excessively pump groundwater, threatening future water security. Research by ETH Zurich and UCSB reveals a sharp decline in groundwater levels exacerbated by agriculture, climate change, and population growth. Despite some successful recovery efforts, urgent global action is needed to address this unsustainable usage and prevent long-term environmental impacts.
