The podcast episodes discuss the significance of migratory species, such as whales, sharks, and even insects like the Bogong moth, and the threats they face from climate change, habitat loss, and human activities.

The episodes highlight the importance of these species in connecting ecosystems, the need for global cooperation to conserve them, and the personal connections people can have with the natural world, as exemplified by the marine ecologist Dr. Alex Hearn's work in the Galapagos Islands.

The episodes provide insights into the first-ever United Nations assessment of migratory species and the recommendations for their protection, as well as the broader environmental challenges and the role of individual actions in addressing them.
