We're in the midst of an environmental crisis, and our urban lifestyles often clash with the natural systems that support us — especially when it comes to how we manage our waste.

Stopping the flow of cross-border pollution can feel like a Sisyphean task. With every effort to tackle it, more trash seems to appear. That's why addressing the pollution crisis at the border takes a multifaceted approach. It involves many different types of interventions — from trash barriers to hillside reforestation to trash collection and repurposing efforts.

In this fourth and final installment of The Planetary Scale, we talk with four fronterizos who have been at the forefront of efforts to mitigate this issue and check back in with old friends from six years ago.

If you have checked our past installments of this series, here are links to Part 1, Part 2 and Part 3.

This episode is dedicated to the loving memory of Steven Wright

Guests:

Waylon Matson of 4walls International

Oscar Romo of AlterTerra

Jorge Ibañez of Las Hormiguitas Nursery

Adela Bonilla of La Casa de las Botellas

We're in the midst of an environmental crisis, and our urban lifestyles often clash with the natural systems that support us — especially when it comes to the materials we use to build. That was the focus of the first two episodes of this “Planetary Scale” series, Part 1 and Part 2.

In this third installment, we follow Itamar “Ita” Lilienthal, an emerging biodesigner and architect who is developing sustainable material alternatives. He believes he may have found a promising biomaterial that could help reduce our environmental impact.

We’ll follow along as Ita leads a workshop where he demonstrates this material and trades insights with another like-minded inventor making waves in the world of biodegradable plastics: Dr. Stephen Mayfield of Algenesis Labs

And if Ita’s last name sounds familiar, it’s because he’s Alan’s younger brother.

In this special Día de Muertos bonus episode, Natalie invites KPBS web producer Leslie Gonzalez to explore Tijuana’s famous Mercado Hidalgo and discover the stunning altar that’s built each year to honor the market’s founding partners who have passed away.

But there’s a twist: Leslie has never actually visited Tijuana. Her parents always warned her that it was too dangerous. Now, this trip becomes a personal journey of discovery, connection, and celebration that goes far beyond the border itself. It immerses her in the colors, flavors, and traditions of Día de Muertos.

Like many cities, Tijuana is rich with folklore and eerie legends. One such tale is the story of Juan Castillo Morales, also known as Juan Soldado, the unofficial patron saint of migrants.

In 1938, Castillo Morales, a military private stationed in Tijuana, was convicted of the rape and murder of 8-year-old Olga Camacho, a girl who lived near the military barracks. However, many believe he was wrongfully accused.

According to local folklore, his spirit still wanders the old cemetery in downtown Tijuana, where some claim to have heard him proclaiming his innocence, among other supernatural occurrences.

We delve deep into this folktale to uncover the truth behind the legend — the historical context, the people involved and the story of how he became known as the patron saint of migrants.

To help distinguish fact from fiction, we spoke with Fernando Escobedo, a historian from Tijuana who has extensively researched the city's past. His work sheds new light on this enigmatic case through the testimony of Fausto Matus, a possible witness to the crime.

Don’t miss this episode, where we unravel the mystery surrounding this iconic legend from Tijuana.

Que onda friends!

Tenemos una serie de reportajes especiales que se centran en los desafíos actuales que enfrenta la región fronteriza: la migración.

La migración es un tema contencioso y polarizante que a menudo los comentaristas políticos utilizan para atacar a sus oponentes, pasando por alto las historias personales de quienes están atrapados en medio de este debate.

Estas historias de esperanza y resiliencia nos recuerdan la importancia de ver más allá de los titulares: reconocer a estas personas como seres humanos. Seres humanos con sueños y aspiraciones, igual que cualquiera.

En la segunda parte de esta edición de nuestros reportajes especiales, nos sentamos a conversar con una exiliada venezolana a quien llamaremos Chama. Chama ingresó legalmente a Estados Unidos en 2022, siguiendo las políticas establecidas por la administración del entonces presidente Joe Biden.

El apodo Chama es un seudónimo. Ella accedió a ser entrevistada con la condición de que Port of Entry no revelara su identidad, ya que carece de estatus legal y teme ser deportada de EE. UU.

En la primera parte, narramos la odisea de Chama para salir de Venezuela y su determinación de reunir a su familia via Tijuana.

Esta segunda parte explora su camino hacia Estados Unidos, el esfuerzo titánico por hacerlo legalmente y cómo, a pesar de todos sus esfuerzos, el sistema terminó fallandole.

Chama se convirtió en una de los cientos de miles de migrantes venezolanos que perdieron su estatus legal debido a una orden ejecutiva del presidente Donald Trump. Como resultado, ahora vive en las sombras, indocumentada—ilegal por decreto.

No se pierdan esta increíble historia de perseverancia.

Hello, friends!

We have a couple of special reports focusing on current issues facing the borderlands: migration.

Migration is a contentious and polarizing topic that pundits often use to score political points against their opponents, overlooking the real stories of people caught in the middle. These stories of hope and resilience remind us of the importance of seeing others as human beings — human beings with dreams and aspirations, just like anyone else.

In the second part of this final installment of our special reports, we sit down with a Venezuelan exile whom we are referring to as Chama. Chama entered the United States legally in 2022, following policies set by President Joe Biden's administration.

Chama is not her real name. She agreed to be interviewed on the condition that Port of Entry not reveal her identity because she lacks legal status and fears deportation from the U.S.

The first chapter of Chama's migrant journey covers her odyssey out of Venezuela and her determination to reunite with her family via Tijuana.

In this second part, we explore her path into the United States, her herculean effort to do it legally, and how, despite all her efforts, the system ultimately failed her.

Chama became one of hundreds of thousands of migrants who lost their legal status due to an executive order by President Donald Trump. As a result, she now lives in the shadows, undocumented — illegal by decree.

You won't want to miss this incredible story of persistence and resoluteness.

En esta segunda y última edición de nuestros reportajes especiales, conversamos con una exiliada venezolana a la que llamaremos Chama.

Chama fue una de los cientos de miles de migrantes que perdieron su estatus legal debido a una orden ejecutiva del ahora presidente Donald Trump. Como resultado, vive actualmente en las sombras, indocumentada.

Este primer episodio explora el primer capítulo de la travesía migratoria de Chama: la odisea para salir de Venezuela y establecerse en Tijuana, y su determinación por reunir a su familia en California.

La segunda parte adentra en su camino hacia Estados Unidos, el esfuerzo sobrehumano por hacerlo de manera legal y cómo, a pesar de todos sus intentos, el sistema finalmente le falló.

No se pierdan esta increíble historia de perseverancia.
