Join Half-Earth! Take the pledge.

Half-Earth offers a solution to the global species extinction crisis that is commensurate with the magnitude of the problem: conserve half the Earth’s lands and seas in order to reverse the species extinction crisis, and ensure the long-term health of the planet.

As a global citizen, I pledge to do what I can to support the Half-Earth Project:

  • Share information about Half-Earth with my network.
  • Participate in local conservation efforts.
  • Support policies that protect the Earth’s lands and oceans

Together, we can protect the bulk of biodiversity for the health of the planet, including ourselves, today and for future generations.

  • This field is for validation purposes and should be left unchanged.

Support the Half-Earth Project

Species diversity is the foundation of a healthy planet. Today, species are going extinct 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.
