As of late, water scarcity has not only become a more widespread problem, but it's worse than scientists previously thought. While it was previously thought that between 1.7-3.1 billion people live with insufficient access to water at least one month out of the year, recent studies have proven that the number has climbed to 4 billion people, that's 70 percent of the global population. Water scarcity is most common in the two most populated parts of the world, India and China, and demand is high. Water scarcity is when consumption is twice as high as supply, this is why it is found in densely populated areas or areas where water is naturally hard to come by, like the Arabian Desert. The consequence of crop failure is economic loss such as crop failure and is a threat to enviromental biodiversity. Studies recommend more rain-fed reliant crops, less irrigation, and what will be most difficult for people, sharing was is accessible.
This can be synthesized back to the World War I era where America was suddenly low on natural resources and started having to rationalize what they had. This included things like "Meatless Tuesdays" and "Wheatless Wednesdays."

This is scary. I wonder what scientists plan on doing
