The podcast episodes provided cover several aspects of global environmental issues, from the pervasive problem of lead contamination in urban soils to the efforts to protect and conserve the Galapagos Islands' marine ecosystem.

For example, the episode 'The hidden danger of lead in soil | Yvette Cabrera' discusses the health risks posed by lead-contaminated soil, particularly for children, and calls for a coordinated global effort to map and remediate this issue. The episode 'A World Beneath Galapagos: Dr Alex Hearn on Hammerhead Sharks, Where Meaning Lies in the Sea, and a Hidden Underwater Swimway Through the Pacific' highlights the importance of marine conservation and the establishment of the Galapagos Marine Reserve, which aims to protect the migratory pathways of endangered marine species.

The episode 'EP 13: Defining Your Own Environmental Activism' also touches on broader environmental challenges, such as the need for effective community outreach and intersectional collaboration to address the climate crisis and other pressing environmental issues.
