Around the world, most major cities are past Day Zero—the day when the water supply is estimated to run out. Currently, one in four people worldwide do not have access to safe drinking water, and 4 billion people live in water-scarce areas, a number that is predicted to rise to 5 billion by 2050.
This issue does not discriminate. Many people on the planet already encounter water stress, which will only be exacerbated as water scarcity increases. It impacts communities from the Middle East and North Africa to places in the United States such as Texas, California, Florida, Arizona, Colorado, and Oklahoma.
