Take the Half-Earth Pledge!

“We ourselves are part of the living world and the only species with the intelligence and thereby the moral responsibility to serve as its caring steward.” —E.O. Wilson

Species are the foundation of a healthy planet. Today, species are going extinct at an alarming rate. Introduced by acclaimed biologist and naturalist E.O. Wilson, Half-Earth offers a solution to the global species extinction crisis: conserve half the Earth’s lands and seas for nature, and ensure the long-term health of our shared planet.

Each action, each conservation project, each species saved is an achievement on the path to this grand goal.

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

  • Take action to support species conservation; start by exploring the Half-Earth Map conservation priorities areas.
  • Share information about Half-Earth with my network; ask friends and family to join you by signing the Half-Earth Pledge; share your pledge with your social media followers.
  • Participate in local conservation efforts; attend a Bioblitz in your area; use the iNaturalist app and upload species observations on your next walk in the woods.
  • Support policies that protect the Earth’s lands and oceans; whether local, regional, or global, each policy action plays a role in reaching the grand, achievable Half-Earth Earth goal.

Together, we can protect half the Earth for biodiversity to ensure that species and people can thrive together, today and for future generations.
