Global Water Shortage Risk Is Worse Than Scientists Thought | HuffPost

The growing risk of worldwide water shortages is worse than scientists previously thought, according to a new study.

About 66 percent, which is 4 billion people, of the world’s population lives without sufficient access to fresh water for at least one month of the year, according to a new paper published Friday in the journal Science Advances.

Previous studies calculated a lower number, estimating that between 1.7 and 3.1 billion people lived with moderate to severe water scarcity for at least a month out of the year.
