Species diversity is the foundation of a healthy planet.

Today, they are disappearing at an alarming rate.

There is a solution.
It’s called Half-Earth.

With science at its core and our transcendent moral obligation to the rest of life at its heart, the Half-Earth Project® is working to conserve half the land and sea to safeguard the bulk of biodiversity, including ourselves.

A Virtual Happy Hour in
Gorongosa National Park

IN CASE YOU MISSED IT! On May 6, 2020, the Half-Earth Project hosted a live virtual happy hour in Gorongosa National Park, Mozambique, where Half-Earth Chair Piotr Naskrecki, Half-Earth Scholar Ricardo Guta, and scientific team member Norina Vicente shared their extraordinary Gorongosa success story, a story that is inspiring and informing other conservation efforts in Africa and around the world, blazing the path to a Half-Earth future.

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.

“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

What does the conservation picture look like in your home region, or in your favorite place on the other side of the world? The ENHANCED Half-Earth Project Map can show you. With the redesigned, intuitive navigation menu and the easy-to-use search function, we invite you to explore species populations, human pressures on those species, and current conservation protections around the globe, wherever your interests lead you.

How to Save the Natural World

Half-Earth Day 2019, held October 7 at UC Berkeley, was a great success, bringing together leaders across multiple disciplines for a conversation about how we can all work together to reach E.O. Wilson’s moonshot of protecting half the lands and seas for biodiversity. During the evening event, E.O. Wilson and Sally Jewell answered questions from the audience, and shared their considerable insights and expertise with the audience. We invite you to view highlights and full video from a great Half-Earth Day.


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.
