Half-Earth Day

Half-Earth Day® convenes people from around the world and across disciplines to share their perspectives and provide thought leadership on how we can work together to safeguard biodiversity and ensure the health of our planet for future generations. Half-Earth Day showcases scientific advances while addressing the cultural moment, empowering conversation around diverse topics, including crucial habitat restoration projects, the intersection of climate change and biodiversity loss, and community wisdom that informs conservation success. Previous speakers have included influential voices like E.O. Wilson, Johan Rockström, Sir David Attenborough, Razan Al Mubarak, Sally Jewell, Cristián Samper, Tom Friedman, Dawn Wright, Paul Simon, Hansjörg Wyss, Hindou Oumarou Ibrahim, Queen Quet, Wade Davis, and many more.

On Half-Earth Day – generally on or around October 22nd – conservationists reflect on the state of biodiversity and convene in partnership with the E.O.
