Many scientists are concerned that the Ogallala aquifer in the United States is being depleted at an alarming rate. What would most likely be a major effect of this aquifer running dry?

The Ogallala aquifer supplies groundwater used to irrigate crops across a large farming region. If it ran dry, farmers would have much less water for irrigation, so many crops could die or yields would fall. It would not eliminate drinking water for most people in the United States or stop the water cycle, and farmers would not automatically have to use salt water.
