A recent study has revealed alarming news about the sinking of major U.S. cities, with 28 significant urban areas, including Houston, New York, and San Francisco, identified as facing land subsidence risks. Groundwater extraction is a leading contributor to this phenomenon, exacerbating concerns about infrastructure stability and public safety. Houston stands out as the fastest sinking city, dropping half an inch annually, followed by others like Seattle and various coastal cities. Experts are urging immediate action to address these issues as millions reside in affected areas, raising questions about the long-term prospects for these urban environments.
