As World’s Springs Vanish, Ripple Effects Alter Ecosystems

Springs, which bring groundwater to the surface and support a host of unique species, are disappearing globally, victims of development and drought. Researchers are working to document and map these life-giving habitats in an effort to save them before they are gone.
