We Have Already Lived Through Our Future—We Just Don’t Remember It is a poetic and thought-provoking film that re-visits ancient forest ecosystems from the earth’s past, imagines future forests in the face of changing climate and shows the forest as a multi-species school, where children practice more-than-human co-existence. We Have Already Lived Through Our Future—We Just Don’t Remember It explores the forest as a site of deep time, ecological transformation, and interspecies learning. Set in the mountainous region of South Tyrol, and shot over a year and across different seasons, the film traces a journey from ancient fossilized forests that evolved during climate change over 280 million years ago through to speculative visions of future forests in a rapidly warming world. Combining scientific inquiry with imaginative storytelling, the film draws paleobotany, climate modelling, and early childhood education to reimagine the forest as both a teacher and a protagonist. However, the main protagonists of the film We Have Already Lived Through Our Future—We Just Don’t Remember It are children who move through the seasons in an intimate kinship with the forest, living and learning in tune with the silvestral environment and helping us imagine a different future based on more-than-human planetary co-existence.
