Four hours east of Los Angeles, in a drought-stricken area of a drought-afflicted state, is a small town called Blythe where alfalfa is king. More than half of the town’s 94,000 acres are bushy blue-green fields growing the crop.

Massive industrial storehouses line the southern end of town, packed with thousands upon thousands of stacks of alfalfa bales ready to be fed to dairy cows – but not cows in California’s Central Valley or Montana’s rangelands.

Instead, the alfalfa will be fed to cows in Saudi Arabia.
