From the ’60s to the ’90s, the city of Tijuana quadrupled its size, but those were, apparently, the slow years. Says Vicky Funari, co-director of “Maquilapolis” (opening this Thursday at the MadCat Women’s International Film Festival), when the North American Free Trade Agreement took effect, in 1994, the border city’s growth moved at a whole new pace. “By 2000,” she wrote to SF360, “there were 4,000 maquiladoras in Mexico employing 1.3 million people.” The result? The city’s infrastructure had no ability to provide the basic services required by so many who’d moved to the area to work for low wages, in horrific conditions within an environment being quickly degraded by the factories’ unmitigated toxic wastes.
