In the early 1800s, an entire forest of oak trees was planted in Sweden for a single purpose: to build the warships of the future. But by the time the trees were ready for harvest in 1975, the world had changed. The Navy no longer built ships from wood. The carefully planned future had never arrived. This wondrous forest holds a profound secret for our time. We live our lives assuming time is a straight line, that the future will be a predictable extension of the present. But in an age of what Margaret Atwood calls not just "climate change" but "everything change," this simple view is failing us. This talk invites you on a journey to learn how to "think time with trees". It's a call to abandon the ticking clock and embrace a deeper understanding of time—one that is interconnected, relational, and stretches across human and non-human generations. Learn how to think time with trees and find a new way to care for our shared future. Christina is Professor of Archaeology at Stockholm and Uppsala Universities.
