Three U.S. trouble spots

Calif. drought
California rancher Nathan Carver (NOT SEEN) drives his truck delivering hay which he now has to buy to feed his herd of beef cattle, seen giving chase across the brown-dirt fields of Carver's ranch on the outskirts of Delano, in California's Central Valley, on February 3, 2014. At this time of the year normally, the fields would be covered in lush green grass, but the western US states' worst drought in decades has reduced the land to a parched moonscape.
