A pair of cave divers prepare to enter the Devil's Ear, a limestone rift in the bottom of Florida's Santa Fe River gushing with crystal clear groundwater from an underlying aquifer. The Devil's Ear is one of Florida's 33 first magnitude springs, the largest category of springs that discharge at least 64 million gallons of water per day. A controversial water bottling facility captures about 1 million gallons of water from the Devil's Ear and nearby springs before it reaches the Santa Fe River every day.

As the magnitude of water shortage issues arise globally, National Geographic Explorers along with the World Freshwater Initiative highlight stories of the communities facing critical challenges. Conservation and education are vital to creating a sustainable future for freshwater use.

As part of the initiative, the World Water Map was launched. Created by the National Geographic Society, in partnership with Utrecht University and Esri, the goal of the map is to provide a geovisualization of global freshwater availability and usage, while identifying critical shortages.
