James Tejani discusses his new book "A Machine to Move Ocean and Earth," which reveals the untold story of how the Port of Los Angeles was carved from 3,400 acres of marshland to become the Western Hemisphere's busiest container port. Unlike San Francisco's natural harbor, this massive engineering project defied both nature and expert opinion. Tejani explores how Civil War generals, Mexican landowners, railroad barons, and government scientists shaped the port's development. Now handling roughly $300 billion in cargo annually, the port represents both tremendous economic success and significant environmental transformation.

After a devastating oil tanker collision in San Francisco Bay in 1971, John Francis made an extraordinary decision that would reshape environmental activism. He chose to stop using motorized transportation and took a vow of silence that would last 17 years. His remarkable journey, captured in the new short documentary "Planetwalker," evolved into a profound meditation on human connection and environmental consciousness. In this conversation, we talk with Francis and the film's directors, Nadia and Dominic Gill, about a story that offers insights into how environmental activism has changed over 50 years, revealing the powerful connection between how we treat each other and how we treat our planet.

Architectural critic Aaron Betsky challenges conventional thinking about our built environment in his new book "Don't Build, Rebuild," in which he makes the case for transforming existing structures rather than constructing new ones. From San Francisco's empty offices to Los Angeles's historic core, Betsky explores how this approach can not only address housing shortages and climate change but also preserve the soul and stories embedded in our buildings. He discusses the economic challenges, policy hurdles, and gentrification paradox while arguing that reimagined architecture can be more beautiful and meaningful than new construction, carrying within it the patina of human experience.

Veteran journalist Joe Mathews offers a post-election analysis of California's future, arguing that the state's path lies not in isolation but in building global alliances — particularly at the local level. While many focus on tensions between the state and federal governments, Mathews suggests California's cities should forge connections with counterparts worldwide who face challenges from authoritarian forces. As national governments falter globally, he argues, local governance becomes increasingly crucial. Drawing from his international expertise, Mathews outlines how California's communities could learn from places all over the world.

San Francisco Chronicle columnist Emily Hoeven examines Gov. Gavin Newsom's heightened relevance following the Democrats' stunning presidential defeat. As the party searches for new leadership, California's ambitious governor seems poised to step onto the national stage. But can the telegenic leader of the world's fifth-largest economy translate his West Coast progressive agenda into a winning formula for Democrats nationwide? Hoeven offers her sharp insights on whether Newsom has what it takes to become the kind of Democrat America would embrace.

Elsa Devienne takes us behind the iconic beaches of Los Angeles to reveal a hidden history of transformation, conflict, and reinvention. The author of "Sand Rush," Devienne discusses how L.A.'s shores went from eroding, polluted strips in the 1920s and '30s to expansive public spaces that defined the city's image and culture. She details the social and political forces that played out, from the exclusion of minority communities to today's ongoing battles over coastal access. With echoes of "Chinatown" and insights into today's wealth-driven coastal fights, Devienne's work helps illuminate Los Angeles' evolving identity.
