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.
