Half-Earth Day®

Half-Earth Day® brings together people from around the world and across disciplines to share their unique perspectives and thought leadership on how we can work together to achieve the goal of Half-Earth and ensure the health of our planet for future generations.

Caring for the environment and human health calls for the best of our science and ingenuity, along with a strong sense of compassion and moral compass. With science at its core, the Half-Earth Project is providing the foundation for a revolutionary movement culture of action, and leading significant scientific innovation regarding the most effective path forward for protection of endangered species and endangered ecosystems. 

Half-Earth Day features distinguished scientists, conservationists, thinkers, educators, and activists working to preserve global biodiversity inspired by a Half-Earth Future. In its 6th year, previous events have been held at the Smithsonian National Museum of Natural History, National Geographic Society, American Museum of Natural History, Royal Geographical Society, Eden Project, and University of California, Berkley. E.O. Wilson, Sir David Attenborough, Dawn Wright, Hindou Oumarou Ibrahim, Rezan Al Mubarak, Glenn Close, and Jeff Corwin have appeared in keynotes, panel discussions and plenaries.
