Learn how trees are able to communicate with each other through a vast root system and symbiotic fungi, called mycorrhizae. -- Most of the forest lives in the shadow of the giants that make up the highest canopy. These are the oldest trees, with hundreds of children and grandchildren. They check in with their neighbors, share food, supplies and wisdom gained over their lives, all while rooted in place. How do they do this? Camille Defrenne and Suzanne Simard explore the vast root system and intricate communication of trees. Lesson by Camille Defrenne and Suzanne Simard, directed by Avi Ofer.

Follow the legend of Parvati, the Hindu mother of the natural world, as she disappears from Earth and reemerges as Annapurna, the goddess of food. -- Historically, the union between Shiva and Parvati was a glorious one: a sacred combination which brought fertility and connection to all living things. Yet a rift had grown between these two forces. Setting out to prove the importance of her work, Parvati withdrew from the world and sent the Earth into darkness. Antara Raychaudhuri and Iseult Gillespie tell the story of the goddess Annapurna. Lesson by Antara Raychaudhuri and Iseult Gillespie, directed by Roxane Campoy, music by Stéphane Gassot.
