As co-created by environmentalists Stephan Poulle and Nicolas Koutsikas, the documentary Gulf Stream and the Next Ice Age argues and provides evidence for the idea that mankind is wreaking permanent and potentially irreversible damage on the ecosystem by interfering with the natural course of the Gulf Stream. Koutsikas and Poulle suggest that this interference, in turn, will prompt a new Ice Age that virtually destroys the modern world.

Pacific Mother journeys from Japan, to Hawaii, Tahiti, Rarotonga and Aotearoa to share interwoven stories of formidable women who live at one with the Pacific Ocean – freediving, spearfishing and paddling waka through its depths and playing with their children in its shallows – a stark contrast to fast-paced lifestyles of larger towns or cities. These women are all mothers who experienced diverse births in hospital, at home and by the sea, with and without medical assistance. Fukumoto also meets Māori and Japanese midwives who share indigenous traditions and rituals around birth that have been lost over recent generations, and are now gradually being reclaimed. Their stories demonstrate just how disconnected the global default maternity system is from the instinctive and cultural needs of mothers and families. They inspire a call to action on birthing rights, as well as a call for parents’ reconnection with their role as nurturers and protectors of their natural environment.
