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.

This documentary follows various migratory bird species on their long journeys from their summer homes to the equator and back, covering thousands of miles and navigating by the stars. These arduous treks are crucial for survival, seeking hospitable climates and food sources. Birds face numerous challenges, including crossing oceans and evading predators, illness, and injury. Although migrations are undertaken as a community, birds disperse into family units once they reach their destinations, and every continent is affected by these migrations, hosting migratory bird species at least part of the year.

Marine biologist and film-maker Rick Rosenthal has travelled three oceans in his attempt to capture them all on film, and in doing so has become a passionate champion for these endangered yet little-known ocean giants.

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.
