Outside of Phoenix, in the scorching Arizona desert, sits a farm that Saudi Arabia's largest dairy uses to make hay for cows back home.

That dairy company, named Almarai, bought the farm last year and has planted thousands of acres of groundwater-guzzling alfalfa to make that hay. Saudi Arabia can't grow its own hay anymore because those crops drained its own ancient aquifer.

Reporter Nathan Halverson tells NPR's Renee Montagne that Almarai bought about 15 square miles in the Arizona desert.

"They got about 15 water wells when they purchased the property. Now, each one of those wells can pump about 1.5 billion gallons of water. It's an incredible amount of water they're going to be drawing up from that aquifer underground," Halverson says.
