“Unless we move quickly to protect global biodiversity, we will soon lose most of the species composing life on Earth.” —E.O. Wilson.

Threats to the natural world are multiplying.
Species are going extinct at an alarming rate.

There’s a solution. It’s called the Half-Earth Project®, the signature program of the E.O. Wilson Biodiversity Foundation. If we conserve half the land and sea, we can still safeguard the bulk of our planet’s biodiversity.

But what would Half-Earth look like? How would we get there?


Edward O. Wilson is one of the leading scientists and among the foremost naturalists in the world.
Dr. Wilson is recognized in both science and literature, as a synthesizer in works stretching from pure biology across to the social sciences and humanities. Wilson is acknowledged as the creator of two scientific disciplines (island biogeography and sociobiology), three unifying concepts for science and the humanities jointly (biophilia, biodiversity studies, and consilience), and two major advances in global biodiversity conservation (the Encyclopedia of Life and Half-Earth.

He has received the U.S. National Medal of Science, the Crafoord Prize (equivalent of the Nobel, for ecology) of the Royal Swedish Academy of Sciences, and the International Prize of Biology of Japan; and in letters, two Pulitzer Prizes in non-fiction, the Nonino and Serono Prizes of Italy and COSMOS Prize of Japan. For his work in conservation, he has received the Gold Medal of the Worldwide Fund for Nature and the Audubon Medal of the Audubon Society.




Help us safeguard biodiversity

Biodiversity is the intricate web of life that sustains nature and sustains us as a part of nature.

With science at its core and our transcendent moral obligation to the rest of life at its heart, Half-Earth Project® is providing the foundation for a new way of understanding the most effective path forward to protect endangered species and ecosystems.


"Earthrise" by Amanda Gorman

"What can we do?
Open your eyes.
Know that the future of
this wise planet
Lies right in sight:
Right in all of us. Trust
this earth uprising.
All of us bring light to exciting solutions never tried before
For it is our hope that implores us, at our uncompromising core,
To keep rising up for an earth more than worth fighting for."

—Amanda Gorman, inaugural National Youth Poet Laureate
Recorded for the Climate Reality Project



Our Indigenous Land Acknowledgement
“The E.O. Wilson Biodiversity Foundation and it's program, The Half-Earth Project, honors the wisdom of the traditional owners of the lands and waters we aim to protect and their ancient ways of seeing and experiencing nature. In the spirit of the oral tradition of the Blackfoot, we aim to honor ‘the flash of the firefly in the night, the breath of the buffalo in the wintertime, and the little shadow that runs across the grass and loses itself in the sunset.’ We aim to restore and protect life. We thank our Indigenous communities for their historic stewardship of life, their critical role in reaffirming and repairing our relationship with it and their present and future partnership.”

– Paula Ehrlich, President & CEO of the E.O. Wilson Biodiversity Foundation and Lead of the Half-Earth Project


The Half-Earth Project is calling on people everywhere to participate in a “moonshot” to care for our planet. Such efforts require broad collaboration across sectors and geographies and the contributions of diverse voices, perspectives, expertise and experience.

At the E.O. Wilson Biodiversity Foundation, we acknowledge that centuries of racism, violence, discrimination and marginalization have obstructed participation of Black, Latinx, Indigenous and Asian people and communities of color in conservation globally. We acknowledge that barriers persist, despite the importance of these individuals and communities as both stakeholders and stewards, ones from whom the world has much to learn. Further, we recognize that the same people who have been systemically excluded from the process are disproportionately hurt by degraded air, lands and waters, perpetuating a cycle of harm and exclusion.

We commit to be part of breaking this cycle. We commit to prioritizing listening and taking clear steps externally and internally to combat racism and oppression of all types. We commit to working toward justice, equity, diversity and inclusion in our leadership, our programs, our strategic planning, our operations, our communications and our fundraising. We commit to creating a culture at the foundation that educates staff and stakeholders on the issues of justice, equity, diversity and inclusion and holds opportunity for traditionally excluded groups to join in processes, activities and decision-making. We welcome and encourage feedback along the way.

We commit to understanding that this body of work IS our work if we are to achieve the goal of Half-Earth and benefit all people and species.
