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.

Join renowned biologist and naturalist E.O. WILSON, award-winning actress and environmental advocate GLENN CLOSE, legendary recording artist PAUL SIMON, and many other special guests including, Jon Jarvis, Hansjörg Wyss, Reggie Love, Kris Tompkins, and members of the Half-Earth Project team and community for an exciting day of virtual programming.

E.O. Wilson Highlights the Joy of Discovery and Adventure in Opening Session of Half-Earth Day

“One word: poetry. That’s what the world has to offer us. A whole series of mysteries, of possible discoveries, of phenomena, of unexpected events, and objects, and things, and living organisms and so on. An infinitude, almost, on this planet, waiting out there to be enjoyed. There’s so many of this in the world waiting to be explored, and savored, and described.”

The Half-Earth Project

Half-Earth is a call to protect half the land and sea in order to manage sufficient habitat to reverse the species extinction crisis and ensure the long-term health of our planet. The Half-Earth Project is bringing this goal to life.

National Report Cards

“With the biodiversity of our planet mapped carefully and soon, the bulk of the Earth’s species, including ourselves, can be saved.” – E.O. Wilson

The most recent update to the Half-Earth Map introduces the National Report Cards and Species Protection Index, which help to measure how many species groups are protected by each country’s conservation efforts, focusing at the national level on how conserved places are protecting the species within them. The National Report Cards can be used to explore how well each country is doing in successfully protecting the species within their country.


Species Discovery

Earth is a little-known planet. Scientists estimate that only 2 million of the planet’s 10 million species have been discovered. Using new technologies and assessment techniques, species discovery is accelerating.


Boots on the Ground

The critical work to fill in the gaps in our knowledge must be done by more “boots on the ground,” a Linnean renaissance of species discovery and taxonomy work led by field biologists around the world.


Conservation Priorities

By mapping the Earth’s species at fine-scale, and in relation to human activities, the Half-Earth Project is identifying and prioritizing the places we need to manage for conservation in order to safeguard the highest number of species. With the biodiversity of our planet mapped carefully and soon, the bulk of Earth’s species, including humans, can be saved.


Green Radio Hour with Jon Bowermaster

Paula Ehrlich, President & CEO of the E.O. Wilson Biodiversity Foundation and lead of the Half-Earth Project, celebrates the upcoming Half-Earth Day in a conversation with Jon Bowermaster, and talks about E.O. Wilson, the science of Half-Earth, and how people are coming together on Half-Earth Day to discuss how they are working to achieve the goal of Half-Earth.

E.O. Wilson – The Linnean Renaissance

Take a look back with us at this 2017 interview with E.O. Wilson discussing the need to re-energize our efforts to discover and describe Earth’s species. ‘We need to explore our world as if we had just landed on a new planet and were discovering its life. There would be no limits to finding every living thing.’

‘Love Nature’ Podcast with E.O. Wilson – Part 2

In Part II of the “Love Nature: The Biophilia Podcast,” E.O. Wilson explores his concept of Half-Earth, a call to protect half the Earth’s land and sea in order to manage sufficient habitat to reverse the species extinction crisis and ensure species have the space they need to thrive. Hear how the Half-Earth Project is bringing this vision to life. (Image of E.O. Wilson by Dave Zoboski.)
