On today's Your Call, we’ll speak with Ken and Melanie Light. They spent five years documenting the Central Valley through photographs and essays for their book, "Valley of Shadows and Dreams." They met people struggling with foreclosures, environmental pollution, water scarcity, immigration, extreme weather, and an ever-widening wage gap. How do we move towards social, economic, and environmental justice for our nation’s bread basket? It’s Your Call, with Holly Kernan and you.
