Half-Earth Day 2026
A landmark celebration of biodiversity, science, and the enduring vision of E.O. Wilson — October 12, Indigenous Peoples Day, at Sanders Theatre, Harvard University.
Join the Museum of Comparative Zoology, the Harvard University Herbaria, the Harvard University Native American Program, the Salata Institute for Climate and Sustainability, and the E.O. Wilson Biodiversity Foundation for Half-Earth Day 2026 — the tenth anniversary of both E.O. Wilson’s landmark book Half-Earth and of Half-Earth Day itself.
The theme is Half-Earth at Ten: Honoring a Legacy of Hope. The day asks the question at the heart of Wilson’s work and life: how do courage, imagination, and wisdom pass from one generation to the next in the service of life on Earth?
The program moves between science, art, and testimony — wild places brought to life through film and photography; Indigenous voices renewing our relationship to land; a tribute to E.O. Wilson through the people who knew him best; poetry and music that carry what data alone cannot; and the presentation of the E.O. Wilson Legacy Award for Transformative Conservation Leadership to the Gorongosa Restoration Project.
Scholar, writer, and artist Adrienne Keene (Cherokee Nation) guides guests through the full program as emcee.
