What really interests me is how long-lived plants allow humans to think about—and emotionally relate to—long units of time. They provide a bridge between human time and geological time. - Jared Farmer

In his Long Now Talk, Geohumanist and historian Jared Farmer shared his multi-faceted approach to understanding our human relationship with trees over millennia. From ancient stories, as objects of reverence, named individuals and clonal organisms, sources of wealth in ancient and modern times, the lungs of the planet and the wood wide web - trees are deeply interwoven with our histories, cultures and growing scientific understanding of our complex global ecosystem. Through his work, Farmer reflects on our long-term relationships with long-lived trees, and considers the future of oldness on a rapidly changing planet.
