In this episode, Karissa and Arielle explore two uplifting stories of transformation. First, they look at how Southern California communities are rebuilding sustainably after the Eaton Fire—repurposing concrete, steel, and trees into roads, buildings, and soil. Then, they dive into groundbreaking canine cancer research showing how dogs are helping scientists detect and treat cancer faster—for both pets and people. Learn how our furry companions are becoming environmental sentinels and how shared biology could unlock longer, healthier lives for us all.
