Nogales, Arizona, is the largest inland food port in the world. Much of the fresh produce trucked up the "food superhighway" of Mexico's west coast comes through there—and a shocking amount of it doesn't travel much farther, dropping into local landfills instead of being sent to consumers.

It's a loss to the farmers who harvested the food and to the consumers who would have eaten it, argue filmmakers Jesse Ash and Phil Bucatello, who made an eight-minute documentary featuring Gary Paul Nabhan, a former MacArthur fellow and advocate for sustainable food reform. The film opens with footage of just-ripe tomatoes being bulldozed.

"If the Florida tomato prices drop on a certain day," Nabhan narrates, "120,000 pounds [of tomatoes] might be thrown into a landfill" in Nogales, while much smaller quantities might end up in food banks or in livestock feed.

Cut to Yolanda Soto, the CEO of Borderlands Food Bank: Borderlands "rescues" between 30 and 40 million pounds of produce each season and distributes it to rural residents, providing fresh fruits and vegetables at less cost than the nearest grocery stores. "Vegetables are expensive," says Soto, and the area has "a very, very high rate of diabetes."
